Zero tolerance
From The Encyclopedia of Earth
The U.S. Department of Agriculture's Food Safety and Inspection Service (FSIS) defines Zero Tolerance as:
In food safety policy, a “zero tolerance” standard generally means that if a potentially dangerous substance (whether microbiological, chemical, or other) is present in or on a product, that product will be considered adulterated and unfit for human consumption. In the meat and poultry inspection program, “zero tolerance” usually refers to USDA’s rule that permits no visible signs of fecal contamination (feces) on meat and poultry carcasses.
