The picture of the pink slime is real. It was pink slime from a meat production plant in China. McDonald's has even acknowledged it. It just wasn't from a specific production plant that McDonald's has used. No photo fakery was involved.
McDonalds switched from mechanically separated poultry to all white meat in 2003. People can thank all those annoying, noisy, filthy, hippy activists who kept pushing fast food corporations to be healthier for this.
These corporations do not make these changes out of the goodness of their personhood hearts. One can also thank activists for pushing the fast food industry and grocery corporations to finally start removing the "boneless lean beef trimmings" pink slime from their products.
In February 2012, fast food chains McDonald's, Taco Bell, and Burger King announced they would stop using BLBT in their food products. In March 2012, the grocery chains Kroger, Safeway, Supervalu, Bi-Lo, and Winn-Dixie announced they would stop buying BLBT products.
Thank the activists for staying on their asses all this time.
These same activists have been the victims of corporate spying in collusion with governmental sources. These same activists were infiltrated and attacked by industry all this time and maligned against with massive public relations campaigns. If you or people you know have a bad opinion, annoyance or distrust of these activists, it's more than likely it's because of the exposure to these vicious public relations campaigns.
