This report examines the food safety performance of suppliers of ground beef to the USDA National School Lunch Program (NSLP). Model results show that establishments that bid on contracts to supply NSLP displayed better food safety performance—in terms of fewer numbers of meat samples testing positive for Salmonella spp —than other establishments supplying ground beef to the commercial market. Results also show that the difference in food safety performance between the types of establishments may have narrowed after 2009. The report provides evidence that some establishments use information about their past food safety performance to decide whether to bid on contracts to supply NSLP.
