If I suspect a piece of food to be bad, I throw it out. I use my senses to determine if it's OK to eat. Does it smell the way I expect it to? Does it feel the way I expect it to? Is it slimy? Does it look like it should? I tossed a red bell pepper last night because it had gotten soft and wrinkly, and when I cut it the cut edge felt slimy. I bought it about 4 days beforehand.
Either I have a cast iron stomach or food poisoning concerns are overwrought, because I don't think I've ever gotten food poisoning.
I've had skim milk turn before the sell by date. Some of it depends on how it is stored both before and after purchasing. However, with leftovers, I generally throw them out after 3-4 days of sitting in the fridge.
