Pink Slime - Good Enough For School Meals, Not McDonald's

School meals containing ammonium hydroxide, also known as treated ground beef or "pink slime", are OK, says the Department of Agriculture, despite growing opposition from parents and various groups. Even, McDonald's, a company not exactly known for healthy, wholesome foods, stopped adding ammonium-treated meat into its hamburgers since August 2011. Celebrity chef, Jamie Oliver, as well as other retractors are said to have influenced McDonald's into excluding the additive. Other fast-food outlets have also stopped using it, including Burger King and Taco Bell.
