Public well being officers in California detected hen flu in a pattern of uncooked milk this month. The virus first unfold to dairy cattle within the US in March.
The invention comes amid an more and more heated public debate in regards to the deserves and disadvantages of uncooked milk.

On the similar time, public well being consultants have continued to advise in opposition to ingesting uncooked milk, which is extra prone to include an array of dangerous micro organism.
Right here’s what you’ll want to know.
What’s uncooked milk and why are folks speaking about it?
Uncooked milk comes straight from the cow (or sheep or goat) and has not been pasteurized. Developed by Louis Pasteur on the finish of the nineteenth century to assist kill dangerous micro organism in wine, pasteurization is the method of heating liquids with a purpose to remove dangerous pathogens and make them secure to drink.
Uncooked milk has been a preferred subject in social media wellness circles for a while. Take one TikTok video posted in 2023 by a complement firm known as Coronary heart and Soil. In it, three younger folks toss a gallon of (presumably uncooked) milk to one another, take a deep swig, and say issues like, “Uncooked milk is usually misunderstood by most individuals,” and “Sadly, many of the milk you discover in grocery shops is pasteurized.”
In one other, Paul Saladino, a preferred health influencer also referred to as Carnivore MD, shirtlessly sings the supposed praises of uncooked milk, saying, “That is nothing like that pasteurized, homogenized milk you get within the retailer, guys.”
In these movies, the phrase “pasteurized” is uttered with a sneer that means it’s a harmful byproduct of humankind’s gluttonous perversions, the best way you would possibly say “microplastics” or “Mountain Dew Code Pink”.
This negativity appears to faucet into the anxiousness many customers really feel about ultra-processed meals. We recurrently hear that the fashionable grocery retailer is a repository of food-like substances, and that one should follow fixed vigilance to keep away from them. However pasteurization doesn’t scale back milk’s dietary worth to that of a soda.
Is uncooked milk secure to drink?
Meals security consultants are “completely horrified” by the rising uncooked milk pattern, says Dr Marion Nestle, the Paulette Goddard professor emerita of vitamin, meals research and public well being at New York College.
“Pasteurizing milk is without doubt one of the nice public well being achievements of the twentieth century,” Nestle says. “Ingesting cow’s milk used to kill infants.”
Nestle provides that she thinks the embrace of uncooked milk goes past an anxiousness about ultra-processed meals – which pasteurized milk, she underscores, is just not. “It’s a part of the entire anti-authoritarian, anti-science, anti-expertise waves that we’re seeing on this nation proper now.”
Uncooked milk’s adherents declare it has extra nutritional vitamins and minerals than pasteurized milk. The CDC disputes this, saying “scientists do not need any proof that exhibits a dietary profit from uncooked milk,” and that “uncooked milk can carry dangerous germs, resembling campylobacter, cryptosporidium, E coli, listeria, brucella, and salmonella”.
These germs can result in meals poisoning and signs resembling diarrhea, abdomen cramping, vomiting, fever, complications and physique aches.
A preferred rejoinder from uncooked milk followers is that people had been ingesting untreated milk for hundreds of years earlier than Pasteur got here alongside. However because the FDA notes, “whereas most wholesome folks will get better from an sickness brought on by dangerous micro organism in uncooked milk – or in meals made with uncooked milk – inside a short while, some can develop signs which can be continual, extreme, and even life threatening.”
Per the CDC, the intense circumstances related to consuming unpasteurized dairy embrace Guillain-Barré syndrome, wherein the physique’s immune system assaults the nerves, and hemolytic uremic syndrome, which impacts the kidneys and the physique’s blood-clotting capabilities.
Nonetheless, greater than two dozen states together with California, Idaho, New Mexico, Pennsylvania and Utah have legalized the sale of uncooked milk. In accordance with research performed by the CDC, between 1998 and 2018, outbreaks linked to uncooked milk led to 2,645 sicknesses and 228 hospitalizations.

However as Dr Yvonne Maldonado, a professor of pediatrics, infectious illnesses and epidemiology at Stanford Drugs, informed the New York Occasions: “Nicely, yeah, you may as well drive round with no seatbelt or trip a bike with no helmet.” The implication: these behaviors are dangerous nonetheless.
“The results of ingesting uncooked milk are so severe,” Nestle says. However whereas these penalties are uncommon, she says, “the chance of getting sick from uncooked milk is increased than the chance of getting sick from pasteurized milk”.
