How many seconds should raw ground beef and pork be cooked to an internal temperature of 155°F before serving?

All ground and mechanically tenderized meats (except poultry, stuffed meat, and stuffing made with meat) should be cooked to a minimum internal temperature of 155°F for at least 17 seconds. Both whole and ground poultry, as well as stuffed meat and stuffings made with meat, should reach a minimum internal temperature of 165°F. There is no time requirement for this temperature - it could be for less than 1 second.
