Final answer:
The FSIS, an agency of the USDA, is primarily responsible for overseeing the safety and quality of meat and poultry imported to the US.
Step-by-step explanation:
The safety and quality of meat and poultry imported to the US are primarily overseen by the Food Safety and Inspection Service (FSIS), which is an agency of the U.S. Department of Agriculture (USDA). While the FDA is responsible for protecting public health by regulating various products including food, the FSIS is specifically tasked with ensuring that the nation's commercial supply of meat, poultry, and egg products is safe, wholesome, and correctly labeled and packaged. It is important to note that the FSIS handles the inspection and quality assurance of domestic and imported meats, whereas the FDA might regulate other imported foods and food products.
