12-Year Old McDonald's Hamburger, Still Looks Edible

Even after 12 long years, this Hamburger from McDonald's still appears edible and hasn't really changed.

The McDonald's hamburger on the right is from the present; the one on the left is from 1996.

The truth is many processed foods don't decompose and won't be eaten by molds, insects or even rodents. Try leaving a tub of margarine outside in your yard and see if anything bothers to eat it. You'll find that the margarine stays seems immortal, too!

Potato chips can last for decades. Frozen pizzas are remarkably resistant to decomposition. And you know those processed Christmas sausages and meats sold around the holiday season? You can keep them for years and they'll never rot.

With meats, the primary reason why they don't decompose is their high sodium content. Salt is a great preservative, as early humans have known for thousands of years. McDonald's meat patties are absolutely loaded with sodium -- so much so that they qualify as "preserved" meat, not even counting the chemicals you might find in the meat.
