The USDA is preparing to enact new food safety rules for school lunches. First up: beef. While not all details are available, one change requires all beef used for schools to be sampled off production lines every fifteen minutes. That’s four times more often than currently required. Any company with a poor safety record will not be permitted to supply food for schools. The USDA purchases 15%-20% of food for school lunches including beef, poultry, eggs, fruit, and vegetables to feed 31 million kids each day. More information at USA Today.
