So I Was just fixing myself some food. a 1lb bag of meatballs and a big jar of sauce. (Im the Yute, yes I always eat like this) While I was cooking the FROZEN bag of metaballs I noticed that expiration date was dec. 9 2005. The sauce's expiration date was from June. Neither of these items had been opened before. Just curious to see if this could kill/seriously harm me. Ive always thought of expiration dates as a "ballpark" thing just looking for some insight...
