McDonald's and Whole Foods have no environmental standards for the meat they sell, and in fact both buy meat from some of the most polluting and environmentally destructive companies on Earth–Cargill and Tyson.
Having access to clean, safe foods is a priority for us all, especially since our friends and our children and grandchildren frequent fast food restaurants; a lot of us shop at Whole Foods, where we hope that the foods are safe to eat.
Cargill has never been a corporation to be trusted. We all grew up with Tyson poultry as a trusted brand, until now. Sometimes I buy have bought Whole Foods' brand of chicken because of price and am now concerned that the sources for their chicken are not safe.
If this is of interest to you, here is a link to sign a petition to McDonalds and Whole Foods:
