An East Tennessee school district served years-old pork to students for lunch and is now implementing new food-handling procedures.

Local media outlets report that the frozen meat had dates of 2009 to 2011 and was served to students in the Hawkins County district on April 22. No sicknesses have been reported.

Director of Schools Steve Starnes says a new inventory system went into effect last Friday. All current frozen items were inventoried, and outdated items were discarded.

Hawkins County Commissioner Michael Herrell says he received a call from a concerned cafeteria worker about the old pork, and he raised questions about the food's safety.

According to the Kingsport Times-News, the Department of Agriculture quality chart recommends eating frozen roasts within 12 months, but it says frozen food remains safe indefinitely.
