Undercooked or untreated pork may harbour pathogens, or can be recontaminated after cooking if left exposed for a long period of time. In one instance, the Food Safety and Inspection Service (FSIS) detected Listeria monocytogenes in 210 kg (460 lb) of Polidori brand fully cooked pork sausage crumbles, although no one was made ill from consumption of the product. The FSIS has previously stated that listeria and other microorganisms must be "...destroyed by proper handling and thorough cooking to an internal temperature of 71 °C (160 °F)," and that other microorganisms, such as E. coli, Salmonella, and Staphylococcus aureus can be found in inadequately cooked pork, poultry, and other meats. The FSIS, a part of the USDA, currently recommends cooking ground pork to 71 °C (160 °F) and whole cuts to 63 °C (145 °F) followed by a 3-minute rest.
