And, if you see all kinds of red flags with this reasoning, join the club. The first concern is in the manufacturer’s plant. How often, and what amount of cornmeal do they test? What is their sample size or AQL? (Acceptance Quality Level). And, do they really test all of their food? Next, how often does the FDA monitor the filth in food? I do not remember any recall of food with maggots, insect parts, or rat excrement unless something has caused illness or death. Perhaps we have to accept some level of “aesthetic” contamination as inevitable, but it is not a comforting thought. You can check the acceptable filth levels of your favorite food in the FDA booklet here. Scroll down in the booklet for the glossary and food listed alphabetically. I wonder if there is an acceptable level of glass. (The image is from our friends at WPClipart).
