A more thorough explanation:

The Food Safety and Inspection Service (FSIS) is a government agency under the U.S. Department of Agriculture. Its main responsibility is to inspect all types of meat, poultry, eggs, and related products to ensure that they are safe for consumption and accurately labeled.

For example, if a company produces chicken nuggets, FSIS inspectors will visit the facility to make sure that the chicken used is not contaminated with harmful bacteria like Salmonella or E. coli. They will also check that the labeling on the packaging accurately reflects the ingredients and nutritional information.

Another example is when a grocery store sells ground beef. FSIS inspectors will check that the meat has been properly handled and stored to prevent contamination. They will also verify that the labeling on the package accurately reflects the type of meat and any added ingredients.

Overall, the FSIS plays an important role in ensuring that the food we eat is safe and accurately labeled. By conducting regular inspections and enforcing strict regulations, they help to protect public health and prevent foodborne illnesses.
