They used to say that Chicago stockyard workers used "everything but the squeal." If you use everything but the gobble, you need to remember several important rules to make sure that table full of lukewarm, breathed-on food is safe to eat later.

William Stallings, MS, RD, clinical dietitian at Temple University Hospital in Philadelphia, says to remember the "2-2-4" formula. This means:

  • 2 hours. Store all leftovers in the refrigerator or freeze no more than two hours after cooking. If food has been out more than two hours, toss it.

  • 2 inches. Use shallow containers, about two inches deep, to store food. This will allow it to cool quickly and evenly, foiling pesky bacteria.

  • 4 days. Eat leftovers within four days. Holiday food kept longer than that should be thrown out. Freeze anything that is not going to be used within four days.

It also is important to keep the fridge at 34 to 40 degrees at all times. Don't forget, while preparing the feast, you probably opened it a lot. The setting may need to be lowered a little at least temporarily.

It is also important during prep time, Stallings tells WebMD, to wash your hands frequently and avoid preparing raw meat on a porous surface, such as a wooden cutting board, that might soak up contaminated juices and transfer them to other foods.
