McDonald's confirmed that it has eliminated the use of ammonium hydroxide - an ingredient in fertilizers, household cleaners and some roll-your-own explosives - in its hamburger meat.

The company denied that its decision was influenced by a months-long campaign by celebrity chef Jamie Oliver to get ammonium-hydroxide-treated meats like chicken and beef out of the U.S. food supply. But it acknowledged this week that it had stopped using the unappetizing pink goo - made from treating otherwise inedible scrap meat with the chemical - several months ago.

Besides being used as a household cleaner and in fertilizers, the compound releases flammable vapors, and with the addition of certain acids, it can be turned into ammonium nitrate, a common component in homemade bombs.

It's regulated by the U.S. Agriculture Department, which classifies it as "generally recognized as safe."
