Visitors exit the U.S. Department of Agriculture’s (USDA) Food Safety and Inspection Service (FSIS) Food Safety Discovery Zone at the Fiesta Oyster Bake on St. Mary’s University campus in San Antonio, TX on April 21, 2012. The USDA FSIS Food Safety Discovery Zone vehicle allows visitors to experience hands-on food safety lessons. The vehicle stops in the smallest towns and big cities like Dallas to educate people on preventing foodborne illness. Real food safety experts who work in meat and poultry plants near each town, such as veterinarians, investigators, and other FSIS personnel staff the events. USDA photo.
