Raw milk has been linked to a minimum of 10 sicknesses in California, in line with the California Department of Public Health. None of the sicknesses has been recognized as chicken flu, the company stated.
“Since saying a number of recollects of uncooked milk resulting from contamination with chicken flu, state and native public well being consultants have acquired studies of sicknesses from 10 people who reported consuming uncooked milk. Initial county and state public well being laboratory testing has not recognized any optimistic chicken flu infections in these people to this point,” a spokesperson stated Thursday.
The division didn’t instantly present further details about the ten sicknesses.
Health officers in Northern California are additionally investigating a possible case of bird flu in a toddler who turned ailing after consuming uncooked milk in November, Marin County Public Health said Tuesday.
The little one went to a neighborhood emergency division with fever and vomiting after consuming uncooked milk and examined optimistic for influenza A, the county said.
Interest in uncooked milk has surged amid help from some high-profile followers, together with Robert F. Kennedy Jr., President-elect Donald Trump’s option to lead the US Department of Health and Human Services.
Although some followers declare there are dietary advantages to consuming uncooked milk, well being consultants say any purported advantages don’t outweigh the related dangers.
Raw milk and a few kinds of uncooked cheese is usually a supply of many sorts of germs, and lab checks present that chicken flu virus in uncooked milk could be infectious.
Raw milk and cream merchandise from Fresno-based Raw Farm had been recalled and distribution of the merchandise was final month halted after samples examined optimistic for chicken flu. In response to the rising presence of the virus, the US Department of Agriculture has introduced that it’s going to start testing uncooked milk saved in dairy silos across the country.
Here’s what meals scientists and dairy professionals say concerning the myths surrounding uncooked milk and the pasteurization course of.
Raw milk has not undergone pasteurization, the method that removes disease-causing germs, yeasts, molds and different dangerous microbes, in line with the US Centers for Disease Control and Prevention.
Raw milk can carry disease-causing bacteria from contaminated udder tissue, residue from milking tools or particles from the water, soil and cow manure, in line with the US Food and Drug Administration. That’s why the CDC recommends consuming and consuming pasteurized milk and dairy merchandise as a substitute.
Most milk within the US is pasteurized utilizing High Temperature Short Time Pasteurization, which includes heating it to a minimum of 161 levels Fahrenheit for at least 15 seconds, in line with the International Dairy Foods Association.
The course of was named after French chemist and microbiologist Louis Pasteur, who refined the method to make use of in alcoholic drinks resembling beer and wine, later adapting the strategy to take advantage of as a approach to take away bovine tuberculosis within the US and Europe within the early 1900s. Roughly 65,000 people died of the illness after eating and drinking unpasteurized dairy products between 1912 to 1937 in England and Wales alone.
Instead of pasteurization, uncooked milk producers monitor the well being of the cow, in line with Raw Farm CEO Mark McAfee.
“We can isolate that cow instantly and ensure she’s OK, and we are able to deal with her,” McAfee informed CNN.
Raw Farm makes use of smaXtec boluses, capsule sensors swallowed by the cows to measure their physique temperature, water consumption, exercise and common well being. The capsules keep in the identical place within the reticulum for the cow’s life, neither digested nor regurgitated.
The gadgets wirelessly transmit updates each 10 minutes. The information is then sorted by AI to supply data rapidly, ought to a cow change into sick, to make sure that the milk is protected to drink.
Despite the hype, the FDA estimates that lower than 1% of Americans drink uncooked milk.
Many followers declare to decide on uncooked over pasteurized milk as a result of they like the style, in line with Dr. William Hallman, a professor and psychologist within the Department of Human Ecology at Rutgers University.
“One of the explanations is that some uncooked milk is just not homogenized, which signifies that cream floats to the highest, for instance, so a few of the first sips could also be filled with cream,” he stated.
There are additionally a wide range of psychological causes, Hallman stated. Some individuals imagine it’s more healthy than pasteurized milk, whereas others may need to help native agriculture or select it as a result of household, buddies or neighbors take pleasure in it. It’s additionally dearer, with some gallons of uncooked milk costing virtually twice as a lot as common milk on the grocery retailer.
“Psychologically, it reinforces the concept that it’s a premium product as a result of in any other case they couldn’t cost a lot for it,” he stated. “There’s sort of this group impact that turns into normalized.”
According to the FDA, most of the claims about uncooked milk’s well being advantages usually are not true. For instance, it doesn’t treatment or deal with bronchial asthma, allergy or lactose intolerance, and it doesn’t have the nice intestine micro organism that might enhance your microbiome.
“Pasteurization is supposed to make sure the dangerous micro organism that may be dangerous to individuals and make them ailing are killed,” stated Dr. Rabia de Latour, a gastroenterologist at NYU’s Grossman School of Medicine. “There’s been lots of current consideration being paid to the idea of ‘processed’ meals being dangerous in your well being. [Pasteurization] nonetheless offers some protein and aids in bone well being by offering calcium and vitamin D to the drinker, however should you’re very involved about your microbiome, I imagine there are safer methods to boost it.”
Some methods to improve your gut microbiome embody consuming high-fiber and fermented meals, fruits, greens and extra virgin olive oil.
Raw milk has a neutral pH and substantial nutritional and water content, making it a great surroundings for micro organism and different dangerous pathogens to develop., analysis reveals.
“Milk has round 87% moisture, and microbes love extra moisture,” stated Alex O’Brien, the meals security and high quality coordinator on the Center for Dairy Research. “The extra out there water, the simpler it’s for them to develop.”
The CDC says that consuming or consuming merchandise constructed from uncooked milk opens the door to several harmful germs, together with E. coli, listeria, salmonella and brucella. Another, Cryptosporidium, can result in very harmful diarrhea in individuals who have HIV or AIDS, de Latour says.
These foodborne sicknesses could cause signs resembling diarrhea, abdomen cramping and vomiting. In uncommon circumstances, they might lead to serious conditions like Guillain-Barré or hemolytic uremic syndrome. The germs usually tend to trigger well being issues in kids beneath 5, adults over 65, pregnant individuals and the immunocompromised.
Raw milk can be utilized to make uncooked cheese, and followers say it has a greater, extra advanced taste than pasteurized cheese. Dr. Don Schaffner, a meals science professor at Rutgers University, stated the well being danger from uncooked milk cheeses could also be considerably decrease, relying on the kind of cheese.
Hard aged uncooked milk cheeses like cheddar, Asiago, Parmesan or Swiss are a lot much less dangerous than delicate uncooked milk cheese like queso fresco, feta, Camembert or Brie, Schaffner stated.
“Soft uncooked milk cheeses usually are not aged … and doubtless pose about the identical degree of danger as uncooked milk itself,” he stated.
The CDC says that delicate cheeses with a excessive moisture content material usually tend to be contaminated with listeria micro organism.
“There’s salt that’s added to cheeses, and there’s rennet and different components that make the cheese curdle the milk,” Hallman stated. “That growing old course of and the addition of salt can mainly scale back the chance of pathogens. It doesn’t imply it’s risk-free, which is why if you’re pregnant or immunocompromised or an older particular person, consuming uncooked milk cheeses could be considerably dangerous.”
The US Public Health Service created the Standard Milk Ordinance in 1924 to advertise pasteurization practices and take away dangerous micro organism that might trigger typhoid and scarlet fevers in addition to tuberculosis.
The ordinance, now often called the Pasteurized Milk Ordinance, outlines the necessities for lab testing of milk and dairy merchandise for high quality and security.
Experts estimate that, earlier than the broader adoption of this strategy, roughly 25% of all disease outbreaks within the US had been milk-borne.
According to the FDA, for each 2 billion servings of pasteurized dairy merchandise consumed within the US, about one particular person turns into ailing.
Pasteurization “has been extremely efficient at decreasing the incidents of milk-borne illness,” Schaffner stated. “Any organic organism has optimum situations that it prefers, and if these deviate, organisms are inactivated. Heat is a really easy expertise that’s straightforward to use with precision, and its impact on pathogenic microorganisms is well-known.”
Some well being consultants imagine that folks might proceed to eat uncooked milk regardless of the well being dangers as a result of they imagine that the general likelihood of sickness is low.
“Some individuals are extraordinarily optimistic, they usually imagine that if there are dangers, they’re extra prone to be more likely to use to different individuals,” Hallman stated. “In this case, they might be focusing totally on the well being advantages and ignoring the dangers as a result of it’s extra handy to try this. They underplay the dangers by overemphasizing the advantages to justify the selection they’ve made.”
Raw milk has change into a very scorching matter due to Kennedy’s vocal support in addition to endorsements from social media influencers and the “Gwyneth Paltrows of the world,” Hallman stated. Paltrow has stated she drinks uncooked cream in her espresso.
“The proof for these well being advantages is definitely not definitive, whereas the dangers definitely are definitive,” he stated. “Having labored on a farm and been round cattle, I can just about guarantee you that every part is just not sterile round these animals. There’s this romanticized view of this, which isn’t fully lifelike.”
The credibility and place of these endorsing the product, like Kennedy, who stated in a social media post in October that uncooked milk was amongst a protracted listing of things that confronted “aggressive suppression,” additionally appears to play a task in uncooked milk’s current consideration.
Sid Miller, the Texas agriculture commissioner, lately argued in an opinion piece on the department’s website that buyers within the state ought to keep the appropriate to buy uncooked dairy merchandise.
“There’s nothing extra American than the liberty to decide on what sort of meals you eat,” he wrote. “Raw milk isn’t for everybody, however that doesn’t imply it shouldn’t be out there. Just as we shouldn’t power individuals to eat one thing they don’t need, the federal government ought to enable individuals the appropriate to decide on what’s finest for his or her private vitamin.”
Hallman stated that some individuals don’t need to be restricted of their choices and informed what they will or can not buy.
“Kind of perversely, some individuals drink uncooked milk as a result of they don’t need the federal government telling them what they need to do,” he stated. “They help consuming uncooked milk as a result of they need to keep their means, their freedom of alternative.”
The FDA notes that one more and more frequent pathogen faraway from uncooked milk throughout the pasteurization course of is H5N1.
This chicken flu virus has precipitated “widespread” sickness in a multistate outbreak amongst US poultry and cows, in line with the CDC.

When cows are contaminated with this pressure of chicken flu, Schaffner stated, the focus of the virus shed in milk could be fairly excessive. “Eventually, cows change into sick and both cease producing milk or produce poor-quality milk,” he stated.
The CDC has reported 58 human circumstances of chicken flu this 12 months, 32 of them in California, the place uncooked milk is authorized to drink and promote. Most of the circumstances are linked to farm staff who’ve been in touch with sick animals.
California additionally reported final month the primary US case recognized in a toddler; the CDC that the virus from that case resembled these beforehand detected in people, cattle and poultry within the state however that it’s not clear how the kid was uncovered.
