The federal regulator of meat, poultry, and egg products, the Food Safety and Inspection Service (FSIS), faces resource limitations that make it more difficult for the agency to ensure the safety of the food supply. Although the agency's budget has risen since it was created, staffing levels have dropped steadily. Widespread vacancies in the agency have spread FSIS's inspection force too thin. Meanwhile, the number of meat, poultry, and egg product recalls has risen, and a recent recall of 143 million pounds of beef is the largest in the nation's history.
