"WASHINGTON - The U.S. Department of Agriculture said on Tuesday it will expand bird-flu testing of beef entering the food supply as part of its response to the ongoing outbreak among dairy cattle, adding that U.S. beef and dairy products remain safe to consume.
USDA officials, in a call with reporters along with staff from other U.S. health agencies, said the tests will begin in mid-September and urged livestock workers to remain vigilant.
Nearly 200 herds in 13 U.S. states have contracted bird flu since March after the virus jumped from wild birds to cows, according to USDA data.
The USDA in May tested 109 beef samples from dairy cows sent to slaughter and found bird flu virus particles in one cow's tissue sample. Older dairy cattle are often slaughtered for ground beef."
