The U.S. Department of Agriculture (USDA) has mandated the testing of dairy cows for bird flu, also known as avian influenza, when being transported across state lines from one farm to another. This move comes after fragments of the bird flu virus were discovered in pasteurized milk, as per a report by NBC News. The USDA's order signifies an escalation of efforts to prevent the spread of this zoonotic disease that could possibly jump from animals to humans. Although it's less common the avian influenza can, indeed, infect cows. As a precautionary measure, the U.S. Food and Drug Administration (FDA) has now decided to test dairy cows for signs of the bird flu virus.A zoonotic disease, avian influenza is typically passed from wild birds to domesticated birds. Instances of it being found in cows are less frequent but not unheard of. The decision to test was triggered because the pasteurization process, although it kills the virus, doesn't remove it, thereby leaving fragments behind which can be detected during testing.Although the threat to public health from these fragments is thought to be low, there is sufficient cause for concern. Direct contact with an infected animal can lead to the transmission of the bird flu virus to humans. Experts though remind that the primary way humans become infected is via close contact with infected poultry or surfaces contaminated by feces from infected birds.The U.S. dairy industry, home to around 9.3 million dairy cows, now faces additional costs and operational hurdles due to these new safety regulations. But considering the potential health risks and the importance of securing the nation's food supply, authorities consider these measures vital in the fight against the bird flu.The USDA's decision underscores the global need for better disease surveillance and prevention in the agricultural industry. It's a reminder that disease outbreaks do not just affect those who are in direct interaction with the animals, but can also have far-reaching effects on the food system and public health at large.This content was created in partnership and with the help of Artificial Intelligence AI
