Key TakeawaysThe FDA has long recommended against consuming raw milk. Because the H5N1 virus has been detected in grocery milk, the agency issued a new advisory reminding consumers to avoid any raw milk products.Pasteurization is a proven method to inactivate viruses and kill harmful bacteria in milk.Despite some claims, there’s no strong evidence that raw milk is more nutritious than pasteurized milk.The Food and Drug Administration (FDA) has always advised against drinking raw milk, but the agency isreminding consumers to avoid unpasteurized dairy productsbecause of the current bird flu outbreak in cattle herds.Clinical samples of raw milk from states including Idaho, Kansas, Michigan, New Mexico, North Carolina, Ohio, South Dakota, and Texas have tested positive for the virus.Multiple domestic cats have died after drinking raw milk and colostrum from infected cows, according to a recent report.The FDA has found that commercially available milk, cottage cheese, and sour cream contain fragments of the bird flu virus.Although additional testing didn’t detect any live, infectious virus in pasteurized products, health experts say to steer clear of raw milk in the meantime.“Raw milk, to me, is a very scary thing. I even recommend those who are feeding milk to their calves to pasteurize it. It’s a very known, tested way to enhance food safety and security,”Michael D. Kleinhenz, DVM, PhD, a dairy cattle veterinarian and a clinical associate professor at Texas A&M University, told Verywell.Is It Safe to Consume Milk and Eggs During Bird Flu Outbreak?Why Is Raw Milk Risky?Testing has shown that pasteurization is effective in inactivating the bird flu virus. Pasteurization, which uses high temperatures to kill germs, has significantly reduced infection rates from various diseases since its widespread adoption in the United States during the 1950s.It remains uncertain if raw milk can transmit the bird flu virus to humans, but unpasteurized milk is known to harbor dangerous pathogens likeSalmonella,E. coli, andListeria.It’s legal to buy raw milk in 27 states, and advocates say it’s healthier and more nutritious than pasteurized milk. However, there’s no strong evidence to support these claims, and pasteurization does not destroy the nutritional value of milk.Raw milk contributes to hundreds of infections in the U.S. each year. Between 1998 and 2008, more than 2,600 illnesses and 228 hospitalizations were associated with raw milk, according to a study published in the journalEpidemiology and Infection.“I think it’s a step backward to continue to promote unpasteurized milk. I think thehealth benefits do not outweigh the disease riskbenefits,” saidScott R.R.

They don’t have that protection mechanism of pasteurization to inactivate that virus and render it dead essentially,” Kleinhenz said.How Does Bird Flu Spread to Humans?What This Means For YouMany public health agencies recommend avoiding raw milk. It is not clear that raw milk can transmit bird flu, but unpasteurized milk can carry plenty of other germs.
