Oh lets just post what it is right here...from your link ..and thank you...
WHAT IS PINK SLIME:
Pink slime is an additive in about 70% of ground beef. Most likely if you have had a fast food burger then you have eaten it.
Pink slime is made from the cheapest, least desirable parts of beef; fat and other trimmings. These are the parts that the butchers cut from the meat,... fall on the floor, swept up ...and usually pay to have them taken away.... These scraps usually used in DOG FOOD!
Now Beef Products Inc. have created a way to make these scraps safe for human consumption..... The process is deceptively simple but the safety is questionable.
First the scraps are put in a centrifuge and spun really fast to separate the little bits of meat from the fat. Keep in mind that these are the scraps off the floor that have pathogens like E. coli 0157 and antibiotic-resistant salmonella. (Sounds like something you would like to eat?)
After the meat is removed, it is combined with AMMONIA to kill these bacteria. Officials at the United States Department of Agriculture endorsed the companys ammonia treatment, and have said it destroys E. coli to an undetectable level. Sure, maybe it is undetectable but it is still there which poses the possibility of food poisoning.
In 2009 school officials temporarily banned their hamburger makers from using meat from a Beef Products facility in Kansas because of salmonella the third suspension in three years. But the facility still remained approved by the U.S.D.A.
