Federal and state officers say pasteurized milk obtainable in grocery shops is secure from fowl flu however caution that raw milk just isn’t.
So how are you aware what you are consuming is secure?
The H5N1 fowl flu virus was first identified in America’s milk supply earlier this year ‒ however the virus researchers discovered was lifeless, killed by the speedy heating of pasteurization.
That’s when officers started warning folks to keep away from uncooked milk, which is touted by some as “more healthy.”
On Friday, officials decided to step up testing of milk on farms, each to maintain the general public from swallowing the virus and to extra shortly establish its unfold amongst farms.
There is little doubt that some unpasteurized milk contains H5N1 virus. Last week, California public well being officers introduced a voluntary recall by Raw Farm LLC after detecting the virus in uncooked milk and cream at firm bottling and storage websites.
Although nobody has but caught fowl flu from their morning cereal or latte, there may be sturdy proof that the virus may be transmitted via uncooked milk.
Still, Raw Farm CEO and founder Mark McAfee questioned why California officers had been asking him to tug his merchandise from cabinets, saying they had been over-reacting since nobody has but gotten sick.
“That’s as a result of that is simply the most recent handy platform to assault authorized uncooked milk in California!” he wrote in an electronic mail to USA TODAY. “Protect shoppers from what???”
Here are some issues to contemplate as you resolve what milk to purchase and drink:
What is uncooked milk?
Raw milk doesn’t undergo pasteurization, a course of developed greater than a century in the past to kill viruses, micro organism and different pathogens. Cheese made with uncooked milk may include pathogens which might be dangerous to folks’s well being, in accordance with the U.S. Department of Agriculture.
Raw milk is authorized for retail sale within California, which is the nation’s largest dairy producer and has had over 500 herds contaminated with fowl flu. Several states ban the sale of uncooked milk fully.
Since 1987, there’s been a federal ban of its gross sales throughout state traces.
Is uncooked milk good for you?
Raw milk supporters say it comprises extra enzymes, probiotics (or the “good micro organism”), proteins and nutritional vitamins than pasteurized milk. They additionally say it helps stop persistent well being points corresponding to asthma and allergies, in addition to ear and respiratory infections and fever, citing studies of European kids dwelling on farms.
There’s little scientific evidence to help these claims, stated John Lucey, director of the University of Wisconsin’s Center for Dairy Research and a meals science professor.
“The quick reply isn’t any, there are not any confirmed advantages,” he instructed USA TODAY.
“You are being conned with these claims,” he stated. “This is snake oil.”
What uncooked milk does include, he stated, is a variety of micro organism, viruses and different pathogens that may make folks sick.
A warning signal is positioned at a dairy farm in Martin, Michigan, U.S., June 6, 2024.
Before pasteurization, folks routinely had been sickened and died from consuming uncooked milk, catching illnesses like tuberculosis, and uncooked milk continues to be much more probably than pasteurized milk to include micro organism like salmonella, E. coli and listeria.
“I don’t have any time for farmers who need to put different folks in danger for merchandise they make on their farm, knowingly,” stated Lucey, who grew up on a dairy farm.
Who can get sick from uncooked milk?
Pathogens in uncooked milk may cause diarrhea, abdomen cramps, vomiting and fever. These might not be critical for some folks, however they will result in critical, even life-threatening diseases for folks with weakened immune techniques, corresponding to infants, younger kids, the aged and pregnant, stated Lucey, who has analyzed risks and benefits of raw milk consumption.
In 2023 and 2024, more than 100 people fell ill from salmonella linked to uncooked milk from Raw Farm, the identical firm now on the heart of uncooked milk remembers for fowl flu. At least seven folks had been hospitalized, and 40% of circumstances had been in kids. Findings solely got here to gentle from courtroom information launched in the summertime, USA TODAY reported.
Bottles of uncooked milk are seen in a show in a Sprouts Farmers Market retailer in Los Angeles, California, on April 29, 2024.
In a July 11 blog post, Raw Farm known as the investigation the results of a “corrupt, biased agenda” together with from the Food and Drug administration and the media. “This is simply the newest of a protracted historical past of soiled methods,” the publish stated. “If you see regarding and questionable headlines, please be very clear we’re in a battle zone with a corrupt system that hates uncooked milk.”
Before that, the corporate’s merchandise had been linked to a number of outbreaks of E. coli, salmonella and campylobacter, in accordance with the University of Wisconsin Center for Dairy Research.
How can pathogens infect uncooked milk?
Bacteria and viruses that may make folks sick are discovered all through farms.
Bacteria like E. coli are current in poop or within the dust, so cows can lie down and get contaminated materials on their udders, stated Dr. Meghan Davis, an affiliate professor of environmental well being and engineering on the Johns Hopkins Bloomberg School of Public Health.
Typically, the milking course of has requirements to wipe down udders and gear earlier than milking begins. But some micro organism can stay and contaminate the milk. Pasteurization kills these pathogens, however they will persist in uncooked milk.
Cows are milked thrice a day on the L & R Dairy Farm close to Marshallville.
Research has shown the highest traces of bird flu virus detected on the cow are round its mammary glands and within the milk itself, stated Davis, a former dairy veterinarian.
Milk samples check constructive for fowl flu lengthy earlier than cows present signs, in accordance with Dr. Ok. Fred Gingrich II, government director of the American Association of Bovine Practitioners, a corporation representing veterinarians who deal with cows.
When bird flu was first identified in cows in Texas earlier this year, barn cats were dying on contaminated dairy farms from consuming uncooked milk, Davis stated. Research has additionally proven ferrets and mice additionally get severely in poor health or die from contaminated milk.
Human circumstances of fowl flu have been largely amongst dairy and poultry employees. In dairies, officials believe transmission to workers occurs once they’re in shut contact with contaminated animals. This contains when individuals are working close to udders and uncooked milk, since that’s the place virus traces are highest. They can then change into contaminated in the event that they contact contaminated gear or milk splashes on them and so they contact their face.
Cows are proven by exhibitors on the state truthful in West Allis, Wisconsin, U.S., August 9, 2024.
For now, infections have been comparatively delicate in dairy employees, together with with eye redness. No one has unfold it to a different particular person, thus far.
However, viruses are always mutating, so officers fear adjustments to fowl flu could make it extra transmissible or trigger extra extreme sickness.
In a study revealed final week, researchers confirmed that just one mutation within the H5N1 virus may make it simpler for it to transmit amongst people. Flu viruses, like H5N1, mutate always, so it is just a matter of time and luck earlier than that mutation occurs, officers have stated.
What does pasteurization do?
Pasteurization is a century-old follow to kill pathogens utilizing warmth, time and strain. Before pasteurized milk was commonplace, one-in-four foodborne illnesses was associated to dairy, in accordance with the FDA.
With fowl flu, pasteurization destroys the virus. So whereas traces of the virus’ genetic materials can nonetheless be discovered, the equipment of the virus is unable to copy, rendering it innocent, Lucey stated.
How can I get probiotics, ‘much less processed’ merchandise?
Just as a result of uncooked milk has excessive ranges of micro organism, it doesn’t suggest these micro organism are helpful or “probiotic,” Davis stated. Probiotics have to be non-pathogenic, whereas uncooked milk can include micro organism that make folks sick, the FDA said in its warning.
By comparability, pasteurized merchandise like yogurt or kefir, do have probiotics from the fermentation course of and have measurable health benefits, including strengthening the immune systems, Davis stated.
In phrases of style, if folks need a “much less processed” milk expertise, she recommends they buy pasteurized complete milk or cream.

As fowl flu continues to brush throughout U.S. dairies, Lucey, of the Center for Dairy Research, hopes folks don’t take dangers simply because fowl flu has solely triggered delicate an infection for now within the U.S. Previous H5N1 outbreaks elsewhere have killed as many as half the people contaminated.
“I’m hoping to God that it doesn’t hurt anyone,” he stated. “But I’m not burying my head in my sand.”
