Salmonella can lurk anywhere and conceal in a rather boiled chicken, mixed throughout the raw eggs within the biscuit dough and even into the feces of animal turtles.

A team of researchers from the Institute for Food and Agricultural Sciences on the University of Florida has created a vaccine that protects salmone stems from non-matters. The vaccine has shown promising in preclinical studies against mice.

Salmonella might be fatal for endangered groups like children under 5 years and older people. According to the US centers for the control and prevention of diseases, 420 people die and 26,5000 are taken to the hospital yearly within the United States for salmonella.

“((Salmonella IS) Bacteria and the infections occur through contaminated food and water. It can also be distributed by faecal pollution or poor hygiene or improper food handling, ”said Mariola Ferraro, an UF -Associate professor who specializes in infectious diseases and is organizing pathogen interactions.

Most infections include diarrhea, fever and stomach cramps. Raw meat, eggs, fruits, Vegetables And animals contaminated with bacteria, especially reptiles, were able to pass on Salmonella. Two active Outbursts of salmonella are currently connected to one another Cucumber And bearded dragons.

“I might not exit and stroke or kiss their backyard chickens because they might be infected with bird flu nowadays or with salmonella,” said Anthony Maurelli, a UF professor for environmental and global health.

The vaccine from UF was tested using Salmonella, which was found from raw water in Gainesville, Florida, in contrast to previous salmonella research that focused on old laboratory trunks. Research continues the legacy of Lisa Emerson, the first author of the study, who died unexpectedly in September 2024 at the age of 29 for natural reasons.

“The query that Lisa asked was how good this vaccine is against tribes that flow into in the true world in Gainesville within the twenty first century?” Said Maurselli. “How well is that this laboratory version of the tribe related to real tribes that flow into on the market and get sick?”

The salmonella used in the vaccine was shed from the feces of infected people, and despite the many microbes existing in the wastewater, Emerson was able to cultivate the trunk. Microbiologists use special paths to grow certain bacteria, a concept that is referred to as selective media. The wastewater was placed in the enrichment broth to grow the salmonella and was transferred to petrios with media, in which foreign bacteria were killed.

The concept of the Salmonella vaccine began in 2015 with research steps in the past five years. Traditional vaccines contain a lively or weakened bacterial base that injects the body with foreign material. However, the salmonella vaccine is cell -free.

“I actually have the sensation that quite a lot of persons are afraid or afraid because, like 'I injee, they’ve a pathogen in my body, which might then mutate and survive.' In our case, there are not any living salmonella bacteria in your body, ”said Saloni Bhimani, a UF -Doctoral student who studies microbiology and cell science. Bhimani is a second creator of the study.

Emerson worked with Andrew Rainey, and the 2 doctoral students were a part of the pre-doctoral student training program for clinical translational science, which brings multidisciplinary laboratory discoveries into real applications. Ferraro was Emerson's mentor.

Emerson, creator of 12 studies, had recently develop into a post-doctoraland scholarship holder of the CDC in Atlanta before she died.

“She has this heritage as a researcher because she really took care of public health. She not only did this to build a career, become famous or something. She actually wanted to make a difference, ”said Ferraro.

Emerson enjoyed volunteering in Animal Shelters and brought her puppy to the Depot Park in Gainesville to support her colleagues once they took part in a weekly 5 km run. A memorial scholarship was created on the UF in her honor.

“She was also very funny and continues to inspire students here. We are still talking a lot about her, ”said Ferraro.

Water that comes directly from natural sources, which is named “raw water”, is Get popularity. Raw water representatives reject public water supply, including tap water, because they don’t benefit from the taste or imagine that it’s uncertain and exhausted by vital minerals.

Raw water appears to be tempting on the surface – the natural environment may look beautiful and the water can look clean and taste refreshing. In contrast to water or in bottles, raw water shouldn’t be evaluated from safety. As a result, individuals who drink it drink liable to infectious microbes or possibly other toxic contaminants.

I’m a Microbiology researcher Study infectious diseases. From the angle of public health, the clarification of misunderstandings about tap water and the health risks of raw water can protect consumers and restrict the spread of infectious diseases.

A brief history of public drinking water

Archaeological evidence indicates that individuals have long connected to one another dirty water with negative health results. Already 1500 BC Chr., Ancient Egyptians Added a binder to his water to scale back contaminants together in an effort to easily remove them.

Two most important developments in the midst of the nineteenth century showed why impure water was dangerous. First, the doctor John Snow pursued a fatal cholera outbreak To contaminated water from the London Broad Street Pump. Second, Louis Pasteur has progressed Germ theory of the diseaseThe postulated that microbes may cause diseases. Pasteur found that consumption fluids corresponding to raw water and milk can have pathogens attributable to the disease.

These discoveries paved the best way for Large infrastructure projects In the twentieth century to be sure that the general public water supply is protected.

Today the Process of cleansing water Starts with the identical steps that the traditional Egyptians used, followed by extensive filtration, to do away with rubble and most germs and chemicals. chlorine Added to kill persistent pathogens, including those that could be within the service ears that carry the water to the faucet. From the Nineteen Fortiesa small amount on fluoride was added as a cheap, protected and effective technique of improving dental health.

The cleanliness and fluoridation of the water supply has decreased dramatically Infectious disease And Cavitiesand was announced as one in every of the twentieth century Success of the best public health.

Is raw water healthier than tap water?

People who’re committed to raw water claim that it has health advantagesHow essential minerals and useful bacteria, that are known as probiotics and are faraway from tap water. Let us unpack each of those claims.

Water dissolves bottom and rock pieces on its source; Hence its mineral content relies on local geology. Areas with a whole lot of limestone corresponding to the center west have water that’s higher in calcium. Water from deeper soil can have a better mineral content, because it flows through more rocks on the method to the surface.

The concept that tap water is exhausted by essential minerals Is not trueBecause these nutrients are too small to be excluded from the filtration process. Test kits can determine the mineral content of your water, and in case you are missing, mineral preparations will be added. However, experts suggest that almost all minerals need them Come out of your weight loss plan, not from water.

Some also claim that raw water Contains probiotics that are faraway from tap water. The amount of probiotics within the water would also vary depending on the placement, and the concept health -promoting bacteria are in raw water was not proven.

There aren’t any studies that associated raw water with health advantages. Anecdotal claims about smoother skin or increased energy are probably placebo effects. Even the concept raw water tastes higher may very well be more psychological than physiological – a study from 2018 showed that almost all people Preferred tap water About filled water in a blind taste test.

Risks of drinking raw water

Raw water carries the chance of a serious stomach intestine infection from a wide range of pathogens.

The water viruses include Rotavirus And Noroviruscause the fast diarrhea and vomiting, and Hepatitis Awhat infects the liver. Bacteria like And Or like parasites And And also cause a serious diarrhea that may result in dangerous dehydration levels. Can also lurk in raw water and cause miscarriages or birth defects in the event that they are consumed while pregnant.

You can transfer the carrier of diarrhea infections to others in case you swim in public pools or don’t wash your hands properly before touching others or preparing food. Norovirus is especially durable and might Survive on surfaces for daysIncreasing probabilities that another person might be infected.

Raw water may also contain Algae that release toxins Cause abdominal problems and damage the brain and the nervous system.

Cholera, ruhr and typhoid are No health burden within the United States Thanks to a strong water treatment system. But areas of the world that lack this privilege suffer High child mortality and widespread diarrhea.

How protected is tap water within the USA?

Tap water within the USA is Drinking under the safest to drink on the planet. The Biden administration has taken steps to further improve it, including financing to exchange lead pipes and recent ones To monitor rules Forever chemicals corresponding to Perfluoralkyl and Polyfluoralkyl substances or PFAs, that are related to cancer and developmental disorders.

It is essential that raw water shouldn’t be necessarily freed from Lead, arsenic, pesticides or industrial impurities. Raw water sources are Not reliably monitored by expertsSo it’s difficult to say which is a less risk. In addition, someday the water will be acceptable, but not on one other. For example, Floor outflow from a storm Could introduce recent germs or pollutants into the world.

The environmental protection authority Routine screens for nearly 100 contaminants To be sure that tap water is protected. In contrast, raw water stays undetected, not regulated and untreated, which implies that his security is questioned. With regard to risks and benefits, there aren’t any proven health advantages from drinking raw water, but clear evidence that they could expose themselves to be malicious and poisonous contaminants.

As the H5N1 bird flu virus continues to spread Poultry flocks and dairy cattleConsumers could also be concerned about whether the U.S. milk supply is protected to drink. According to the U.S. Food and Drug Administration, the reply is yes. so long as the milk is pasteurized.

However, in late November 2024, California regulators recalled two batches of raw, unpasteurized milk from a dairy farm in Fresno after the bird flu virus was detected within the milk. The dairy afterwards has recalled all of its raw milk and cream products from trade because of possible bird flu infection. State regulators quarantined the farm and halted any redistribution of its raw milk, cream, kefir, butter and cheese products made on or after Nov. 27.

Immediately following the recalls, no cases of human avian influenza linked to the milk were identified. However, officials urged shoppers to not drink the raw milk from the affected batches and to return it to the shop where they purchased it.

Despite warnings from health experts that it could contain raw milk high concentrations of the bird flu virustogether with many other pathogens, Raw milk sales within the USA have increased. Robert F. Kennedy Jr., President-elect Donald Trump has said he’ll nominate head of the Department of Health and Human Services, has claimed that raw milk “promotes human health.” contrary to the warnings of FDA officials and food scientists.

As Extension Food Scientist in a state where the sale of raw milk is legalI provide technical support to assist processors produce prime quality and protected dairy products. I also wish to help people understand the confusing world of pasteurization methods on their milk labels and why experts strongly advise against consuming raw milk and products comprised of it.

What could make milk unsafe?

Dairy products, like many foods, pose risks that may lead to numerous illnesses and even death. Milk comes from animals that graze outdoors, live in stables and lie in mud and dung. The milk is picked up from the farm by tanker trucks and delivered to the processing plant. These environments provide quite a few opportunities for contamination by pathogens that cause disease and produce organisms that cause food spoilage.

For example, comes from environmental sources comparable to soil and water. Mild infections with listeriosis cause flu-like symptoms. Unfortunately, more serious cases are too common and might result in miscarriages in pregnant women in extreme cases even death.

Other pathogens commonly related to dairy animals and raw milk contain which may cause serious gastrointestinal infections and result in kidney damage; essentially the most common reason for diarrheal illness within the United States; And which cause abdominal pain, diarrhea and other symptoms.

Store drinks safely with heat

In the 1860s French microbiologist Louis Pasteur discovered that heating wine and beer killed the organisms that caused spoilage, which was a major problem in France on the time.

This heating process that became often called pasteurizationwas introduced to the United States before World War II, at a time when milk was in charge 25% of all foodborne illness outbreaks within the United States. In 1973, the federal government required that each one milk sold across state lines within the United States be pasteurized, and in 1987 this became the case Prohibition of interstate sales of raw milk.

Pasteurization involves heating each particle of a food to a particular temperature over a continuous time period to kill the product's most heat-resistant pathogen. Different organisms react in another way to heat. Therefore, controlled scientific studies are needed to find out how long a given organism will kill at a given temperature.

Since 1924, the policy has guided pasteurization within the United States Class “A” pasteurized milk regulation.a federal guide that’s updated every two years to reflect the present state of science adopted by all 50 states. Pasteurization equipment within the United States must meet strict requirements, including sanitary design, safety controls, and material standards.

Pasteurization methods

Dairy processors can choose from various kinds of pasteurization. When used accurately, all of those methods result in the identical result: germ-free milk. To provide an extra margin of safety or to cut back bacteria that could cause milk to spoil, processors may treat milk beyond minimum times or temperatures, extending the product's shelf life.

Smaller processors that process limited quantities use so-called Vat pasteurizersalso called batch pasteurizers. The milk is pumped right into a temperature-controlled tank using an agitator, heated to not less than 63 degrees Celsius and kept there repeatedly for half-hour. It is then cooled and pumped out of the vat.

The mostly used method for business milk is High-temperature short-term pasteurizationwith which large quantities of milk could be treated. Milk is pumped at high speed through a series of thin plates to succeed in a minimum temperature of 161 F (71 °C). It then travels through a holding tube for 15 seconds, whereby the temperature is mechanically checked and cooled for safety.

The most complex and expensive systems are Ultra-pasteurizers and ultra-high temperature pasteurizersPasteurize the milk in only a number of seconds at temperatures above 285 F (140 C). This approach destroys many spoilage-causing organisms and provides the milk a significantly longer shelf life than other methods, although products made this fashion sometimes have more of a “cooked” taste.

Ultra-high temperature products are processed in a sterile environment and packaged in sterile packaging comparable to lined boxes and bags. They can last as long as a yr before being opened. Ultra-high temperature packaging makes it protected for kids to take milk to high school for lunch day-after-day.

Bird flu in milk

Detecting avian influenza virus fragments in milk is a brand new challenge for the dairy industry. Scientists don't have an entire picture of the risks to humans, but they’re learning.

Previous research has shown that virus particles enter the milk of infected cows, but that The virus is inactivated by pasteurization. The FDA advises consumers to not drink raw milk because there is proscribed details about it whether it might probably transmit bird flu.

The agency also urges manufacturers not to supply or sell raw milk or raw milk products, including cheese, comprised of milk from cows showing symptoms of illness.

Bird flu occurs time and again in recent speciesand from the start of December 2024 There have been 57 confirmed human cases within the United States. Of these, all but two were individuals who worked with livestock.

Two current cases – a baby in California and an adolescent in Canada – could suggest that young individuals with immature immune systems are more at risk of the virus than adults. While medical researchers are still determining how H5N1 is transmitted, I agree with the FDA that raw milk poses risks that will not be value taking.

Concerned that a drink containing infected raw milk could cause the H5N1 bird flu virus to spread to humans, state health officials have ordered it All raw milk and cream from a Fresno-based dairy farm might be faraway from store shelves.

Consumers should return purchased milk to the shop where it was purchased, they add.

“Californians are strongly advised not to consume any raw milk or cream products in their possession or still on store shelves,” the California Department of Public Health said in a press release released Monday evening. Pasteurized milk, which kills the virus and other pathogens, stays drinkable.

Dairy products from Raw farm, The state's top raw milk producer has tested positive for bird flu in recent days, each in retail and dairy storage and bottling operations, officials said.

This is a broader recall than announced last week after contaminated Raw Farm products from two specific batches were discovered at retail stores in Santa Clara Countyf milk. The Santa Clara County Department of Public Health said it was unable to authorize the discharge of the names of the stores.

As the disease investigation continues, Raw Farm is cooperating fully with CDPH and the California Department of Food and Agriculture.

But Raw Food CEO Mark McAfee — who said he was asked to use for an advisory position on the U.S. Food and Drug Administration in the brand new Trump administration — called the recall and quarantine “a political issue “. There are no food safety issues with our products.” he wrote on the corporate's website.

“We are working to resolve this policy issue while engaging with our state regulators,” he wrote. “Our family business has had to face many political challenges and we are resilient.”

No one has contracted bird flu after drinking raw milk products from this dairy.

However, it is understood that contact with infected raw milk could cause illness. As the virus has swept through the state's dairy industry, infecting 493 of the state's 1,100 operators, an estimated 30 California dairy farmers have fallen unwell.

“Drinking or accidentally inhaling raw milk that contains avian influenza viruses can lead to illness,” in keeping with CDPH. “In addition, touching your eyes, nose or mouth with unwashed hands after contact with raw milk containing the avian influenza virus can also lead to infection.”

Research published within the New England Journal of Medicine shows that the virus can persist contagious in raw milk for at the least several weeks if kept refrigerated at 39 degrees Fahrenheit.

Cats consuming infected raw milk Infected and dead animals have died in farm “bulk tanks,” in keeping with a report from the Centers for Disease Control and Prevention. Subsequent autopsies revealed a severe systemic viral infection in these animals, affecting organs similar to the brain and eyes Michael Payne of the Western Institute for Food Safety and Security at UC Davis.

The virus spreads through aerosol particles and contaminated milking equipment. While most affected animals get better with supportive treatment, an estimated 10 to fifteen% of cows die. said Anja Raudabaugh, CEO of Western United Dairies. Many never return to their previous productivity.

The virus currently only attacks the cells of animals. But it's only one or two mutations away from attacking people's cells, virologists say. As it spreads, the likelihood that a mutation will arise increases.

The virus appears to attack a cow's udder cells. This could explain why younger cows and cattle weren’t affected.

Following the CDPH investigation, Raw Farm is under quarantine for greater than two months, meaning it will not be permitted to remove cattle from the property or sell any brand of raw milk products.

McAfee is allowed to sell milk from its 1,800-cow dairy to a processor that pasteurizes it and uses it in various products, including milk or cheese.

According to CDFA rules, milk testing begins again when there aren’t any more sick cows inside 60 days. Before the milk might be released, the dairy must test negative in three tests, with seven days between tests.

Raw milk is taken into account so unsafe that the U.S. Food and Drug Administration bans interstate sales.

But individual states still control raw milk sales inside their borders – and California is certainly one of twelve states that allow purchasing in retail stores.

Raw Farm has been linked to a wide range of other outbreaks of pathogens that don’t have anything to do with the bird flu virus, including the bacteria Salmonella, E. coli and Campylobacter. According to a recently filed lawsuit by a Seattle-based attorney Bill MarlerVictims of a salmonella outbreak between September 2023 and March 2024 include at the least six Alameda County residents, five Contra Costa County residents and five Santa Clara County residents.

Instead of banning raw milk, California is counting on promoting restrictions and warning labels to tell consumers about risks.

If the state or federal government finds that a food company is egregious in its safety or sanitation practices, it might be forced to suspend operations until it implements programs that exhibit compliance, in keeping with UC Davis' Payne.

There have been no reports of illnesses related to the avian influenza virus, which was identified this weekend in a retail sample of raw milk from a Fresno-based dairy.

But the dairy behind bird flu detection, Raw Farm LLC, is identical company that has been selling contaminated products which have caused many illnesses for the past twenty years.

In February, 11 people became unwell after eating Raw Farm's cheddar cheesebased on the U.S. Centers for Disease Control. Of these, five needed to be hospitalized.

Last 12 months, state authorities issued three recalls of its products. The bacteria Campylobacter has been present in milk And Salmonella has been present in cheese, milk and cream. Between 2012 And 2023At least 35 people became unwell after eating the raw products, which also led to recalls, data from the CDC and the U.S. Food and Drug Administration show.

“I almost killed my son when I made the decision to give him raw milk,” he said Mary McGonigle Martin of Murrieta, whose son Christopher nearly died in 2006 from hemolytic uremic syndrome brought on by E. coli bacteria after drinking raw milk that she said was purchased from the farm formerly referred to as Organic Pastures.

“He recovered from kidney failure, heart failure, a collapsed lung, acute pancreatitis, high blood pressure and seizures,” said McGonigle-Martin, who’s now the nonprofit’s board chair Stop foodborne illnesses. “When I made the decision to give my son raw milk, I didn’t know that something so terrible could happen to him.”

A spokesman for Raw Farms didn’t immediately reply to a request for comment.

A brand new potential threat is bird flu in raw milk that has not been pasteurized, a process that uses high heat to kill germs. Experts fear President-elect Donald Trump's entry of Robert F. Kennedy Jr. to guide the U.S. Department of Health and Human Services could increase exposure to the virus.

More than 400 herds of cattle have now tested positive for the virus, accounting for 40% of the state's dairy industry.

In the USA, 53 persons are infected with bird flu. Of these, 21 got here from poultry, 31 from dairy cows and one from unknown sources. In California, nearly the entire 29 human cases within the state are linked to dairy farms.

According to the state and county, on Nov. 21, Santa Clara County health officials identified the bird virus in a sample of raw whole milk they purchased at a retail store they didn’t name. The district contacted stores Friday and beneficial they remove the raw milk from sale.

In the meantime, Raw Farms has issued a voluntary recall of raw milk with lot number 20241109 and a best before date of November 27, 2024.

Food scientists warn that not only bird flu but other dangerous microbes have been shown to lurk in unpasteurized milk, a process that uses high heat to kill germs.

“The risk of possible infection from a pathogen that comes from raw milk is significantly higher than with pasteurized milk,” he said David A. Mills, professor within the Department of Food Science & Technology at UC Davis.

We asked food scientists questions on raw milk, pasteurization and the growing problem of bird flu.

Q: Can I catch bird flu from raw milk?

A: To date, there have been no human cases attributed to the consumption of raw milk. But in April, barn cats in Texas died after drinking raw milk from an infected dairy cow. The cats showed symptoms similar to depression, stiff body movements and blindness. Laboratory studies have shown similar results.

A study conducted on mice, reported within the May issue of the New England Journal of Medicine, concluded that the virus in “untreated milk can infect susceptible animals that consume it.”

Q: How do microbes get into milk?

A: Even healthy dairy cows can contaminate the milk with dangerous bacteria similar to E. coli.

That's not simply because the udders are near the rectum, Mills said.

“If you're on a farm and you have a lot of livestock, there's a little more droppings than most places,” Mills said. “Transfers will take place.”

After the milk is collected, small amounts of bacteria can multiply and grow.

Q: Why does pasteurization make milk secure?

A: Pasteurization kills bacteria through the use of heat to vary the form of the enzymes and the cell structure of the organism.

The exact temperature and time relies on the batch. Milk will be heated to no less than 145 degrees for no less than half-hour or 161 degrees for 15 seconds. in a big pool. Pasteurization can extend the shelf lifetime of food by several days or perhaps weeks.

Q: Is raw milk legal in California?

A: About 20 states ban the sale of raw milk, but it will probably be legally sold in California if a California dairy farm meets certain sanitation and licensing requirements, based on the state Department of Health. Animals have to be tested for certain diseases, including brucellosis and tuberculosis.

However, these requirements cannot guarantee that a dairy farm will produce raw milk products which might be freed from harmful germs, said tThe California Department of Public Health. Therefore, firms that produce and sell raw milk must display a warning label on all raw milk products.

Q: Isn't raw milk purported to be healthy?

A:According to CDPH, there isn’t any difference in dietary value between raw milk and pasteurized milk.

Raw milk shouldn’t be the identical as organic milk or milk that comes from grass-fed animals. Raw milk can still contain harmful bacteria and other germs.

Raw milk also cannot give you “good bacteria,” sometimes called “probiotics.” According to CDPH, probiotics are present in pasteurized dairy products like yogurt or kefir, that are safer to eat than raw milk.

Q: What is dangerous about raw milk?

A: A 2017 study found that unpasteurized milk, consumed by only 3.2% of the population, and cheese, consumed by just one.6% of the population, caused 96% of illnesses brought on by contaminated dairy products be caused.

In the United States, outbreaks linked to unpasteurized dairy products cause a mean of 760 illnesses and 22 hospitalizations per 12 months, primarily as a consequence of germs similar to Campylobacter and Salmonella. based on CDC.

The biggest risks come from these bacteria:

• Campylobacter: This pathogen may cause reactive arthritis and Guillain-Barre syndrome, which results in paralysis.

• Salmonella: This pathogen may cause a blood infection, irritable bowel syndrome, and reactive arthritis. Antibiotic resistance makes it difficult to treat salmonella.

• Ecoli. 0157:H7: This pathogen may cause hemolytic uremic syndrome (HUS), essentially the most common explanation for kidney failure in children. Some children will eventually need a kidney transplant. Children that suffer from HUS may additionally lose part or all of their colon, suffer from pancreatitis, seizures and strokes. Seizures and strokes may cause everlasting neurological damage.

The biggest risk of great illness is in children under 5, adults over 65, pregnant women and other people with weakened immune systems. In general, most victims are children.

Additionally, raw milk can contain high levels of antimicrobial resistance genes when stored at room temperature a study by researchers at UC Davis. Bacteria with antimicrobial resistance genes, when passed on to a pathogen, can turn into “superbugs,” meaning that drugs used to treat infections or illnesses now not work.

State health officials confirmed Sunday that the H5N1 avian influenza virus was detected in a retail sample of raw milk from Fresno-based dairy Raw Farm.

The sample was collected by Santa Clara County Health Department officials.

Raw Farm has issued a voluntary recall for all quart and half-gallon dairy products manufactured on November ninth with an expiration date of November twenty seventh and lot ID #20241109.

To date, there have been no reports of illness related to this recall.

Last week, the CDC reported that samples from a baby in Alameda County who had mild respiratory symptoms were positive for H5N1. It is unclear how the kid was exposed to the virus, although investigators ruled out contact with infected dairy or poultry animals. They also excluded raw milk.

Across California, 29 people have tested positive for the virus, all but one — the kid in Alameda County — are dairy employees. Statewide, the number is 55, with 32 exposed through dairy products, 21 through poultry and two with no known source.

In addition, an adolescent in British Columbia has also been infected and has been in critical condition for greater than two weeks. The source of this child's infection also stays unknown.

Since March, 402 California dairy herds have tested positive within the state; Nationwide, 616 herds tested positive.

Mark McAfee, the owner of Raw Farm, said the tests he and the California Department of Food and Agriculture have conducted on his milk – since he began voluntary testing in late April – have all come back negative.

“Over the past two days, CDFA has collected additional dairy samples from our bulk farm tanks and even retail samples and they are all officially negative for HPAI,” he wrote in an announcement. HPAI is the abbreviation for Highly Pathogenic Avian Influenza; It is commonly used interchangeably with H5N1 and other highly pathogenic avian influenza strains.

Raw Farm is the biggest producer and retailer of raw milk within the state, where the product is sold legally in retail stores. McAfee said he has about 1,800 head of cattle on two dairies – one in Fresno, the opposite near Hanford.

The U.S. Food and Drug Administration doesn’t allow the interstate transfer of raw milk for human consumption and advises the general public to not drink or devour raw milk products. Officials say pasteurization inactivates the virus.

Several states have recently modified their laws to legalize raw milk products, including Iowa, Louisiana and Delaware – all of which modified their laws this spring to permit broader access for consumers.

Additionally, Robert F. Kennedy Jr., President-elect Trump's Health and Human Services nominee, is a vocal supporter of raw milk and has stated that he wants to extend people's access to unpasteurized milk.

Raw Farm's recall notice asks stores to remove the product from shelves and encourages consumers to return the product to the shop where it was purchased for a free substitute or refund.

MCafee said it was unlikely that any of the products would remain on shelves.

“It’s all gone,” he said. “We take back anything that isn’t sold after seven days.”

The virus has appeared in wastewater sites throughout Santa Clara County, including Palo Alto, San Jose, Gilroy and Sunnyvale.

It was also detected in 24 of the 28 California wastewater systems tested by WastewaterScan — an infectious disease surveillance network led by researchers at Stanford, Emory University, with lab testing partner Verily, Alphabet Inc.'s life sciences organization becomes.

We live in a “very charged time for raw milk,” MCafee said. “It’s all over the news that RFK is announcing that he wants raw milk for everyone to improve immunity and the gut microbiome in America.”

“Our mission is to feed our consumers the highest quality raw milk, and that’s exactly what we do,” he said, citing his testing record and history with the state Department of Agriculture.

What is pasteurization? Does it destroy nutrients?

Pasteurization is a process during which beverages and foods are heated to high temperatures—over 145 degrees Fahrenheit (62.78 degrees Celsius)—to kill harmful microorganisms resembling bacteria, viruses and parasites. This reduces the general variety of microorganisms within the product and inactivates enzymes that might contribute to spoilage.

The taste, dietary value and quality of pasteurized products will not be significantly affected by the method.

While pasteurization may lead to some nutrient losses, Changes are generally minimal and outweighed by the advantages. Pasteurization typically causes a slight denaturation of proteins and has little effect on fats and carbohydrates. While water-soluble vitamins resembling Vitamin C and a few B vitamins that will not be often abundant in milk, except vitamin B2may be partially broken down during pasteurization, fat-soluble vitamins (A, D, E and K, that are present in significant quantities in milk) are more heat-stable and are only minimally lost.

Therefore, nutrient losses in milk because of pasteurization are generally small in comparison with the numerous advantages resulting from the reduction of foodborne illness and spoilage.

Is raw milk healthier than pasteurized milk?

Studies have compared the benefits of raw milk with pasteurized milk and have found little evidence that raw milk is superior to pasteurized milk. The perceived advantages of raw milk are outweighed by the health risks.

First, raw milk doesn’t improve lactose intolerance.

Raw milk too has no more vitamins than pasteurized milk. Milk shouldn’t be a great source of vitamin C or other heat-sensitive vitamins, and pasteurization contributes little to the reduction of vitamin B2 or riboflavin, which shouldn’t be as heat sensitive. In addition Vitamin D is added to pasteurized milk to enhance the Ability to soak up calcium in milk.

Fortified milk replaces nutrients which may be lost within the pasteurization process. Vitamin D is added to exploit to enhance the absorption of the calcium present in milk. No single food is ideal, so it's OK if milk is lacking some nutrients, as these may be obtained from other foods.

Some people imagine that probiotics – foods or supplements that contain live bacteria which can be helpful to health – are more common in unpasteurized milk and raw milk products. However, raw milk is usually Lack of probiotics and has significantly more harmful bacteria. Probiotics are added to many dairy products resembling yoghurt after pasteurization.

In addition, a 2011 review of obtainable research on the health advantages of raw milk found that a lot of these studies carried out with poor methodswhich implies that their results ought to be interpreted with caution.

What health risks are there in consuming raw milk?

The health risks related to consuming raw, unpasteurized milk arise from the harmful microorganisms it could contain.

Raw milk is related to Hundreds of outbreaks of foodborne illnessesBetween 1998 and 2018 202 outbreaks resulted in 2,645 illnesses and 228 hospitalizations. More recently, from 2022 to 2023, there have been 18 outbreaks and recalls related to raw milk. Number of outbreaks and reminds In reference to pathogens in raw milk, there have already been several cases of illness in 2024. In all cases, pathogens contained in raw milk that cause disease in humans were directly liable for these illnesses.

Some diseases attributable to pathogens in raw milk can serious long-term consequencesincluding paralysis, kidney failure and death.

Researchers found that areas where raw milk was legally sold within the United States from 1998 to 2018, over 3 times more outbreaks than in areas where the sale of raw milk was illegal.
