It depends on the food. Meat, milk, shellfish, BAD BAD idea. Tastes lousy most of the time anyhow. Bread that's stale is fine, make french toast out of it. Vegetables are hit and miss, but mostly the stuff that decays them won't make you sick. Tomatoes are done for with a little fuzz, plantains are edible for a long, long time. Chips are so slaty they're hard to spoil but they can taste stale. Cheese can be salvaged ect ect. Your poll REALLY needs a "depends on the food" option.
