The U.S. Department of Agriculture (USDA) is urging poultry producers to increase testing and monitoring of turkeys for bird flu to prevent the virus from entering the food supply. The mandatory isolation, monitoring, and testing of flocks of over 500 birds within 72 hours of slaughter are being implemented in Minnesota and South Dakota, with possible expansion to other states. This measure is voluntary but supported by states and the industry. The new measures are a response to a cat food recall and an instance of a cat dying from bird flu after eating contaminated food, as well as human cases of bird flu. The USDA's actions aim to limit the spread of the virus and restore consumer and trading partner trust.
