Yesterday on a news show, I only caught part of it but it was about the high price of food especially breakfast foods. The news said that some people are buying cereal, eggs and milk at what they called "big box" or "chain discount" stores who sell for less because the food is "past its due date" - they said "past its due date" which I take to mean it is expired. When is it safe to eat "expired" foods and how do you know before you buy it? Common sense would tell you that if you crack open an egg and it stinks, don't eat it and same with milk. But how would you know before you pay for it and get it home? What foods are safe to eat "expired" but what foods are not? Thanks if anyone knows.
