Approximately 20% of retail samples of commercial milk have tested positive for traces of bird flu, according to the Food and Drug Administration (FDA). This follows the initial detection of avian flu in Texas herds in March, which has since been found in more than three dozen herds in eight states, including Idaho, Kansas, Michigan, New Mexico, North Carolina, Ohio, South Dakota, and Texas. The FDA continues to analyze the data, with initial results indicating a higher proportion of positive results in areas with infected herds. Despite these findings, the FDA maintains that milk is still safe to consume, with retail milk studies not indicating any reason to change this assessment. Dairy cattle moving between states are now required to be tested for the virus to control the growing outbreak. Every lactating cow must now test negative before crossing state lines. Egg producers are also on high alert after chickens tested positive for the virus in Texas and Michigan. Officials have responded by culling millions of birds, while the FDA continues to maintain that the risk of human infection is low.
