Still eating Thanksgiving leftovers?It might be time to stop. It's been 6 days since Thanksgiving, and if you still have leftovers in the fridge, you should probably throw them out. And if you're still eating them, you better have some Pepto Bismol standing by. TheU.S. Department of Agriculturerecommends discarding uneaten leftovers three or four days after they're cooked, which means that you needed to finish it all by Monday -- or at least tossed it in the freezer. And the USDA says leftovers can safely remain in the freezer for up to six months, although the quality of the food may suffer.
