The top veterinarians overseeing the bird flu response at the Food and Drug Administration's Center for Veterinary Medicine were laid off on Tuesday, as part of sweeping cuts ordered by Health and Human Services Secretary Robert F. Kennedy Jr. to the nation's health agencies.

The job cuts have impacted researchers, scientists, and senior officials, leading to the loss of key figures who shaped U.S. policies on drug approvals, medical research, and public health.

Federal health officials have warned against the consumption of raw milk, which can carry a host of pathogens, because of the bird flu outbreak. Nearly one thousand U.S. dairy cattle herds have been infected with the virus over the past year. Kennedy has been a proponent of raw milk.
