FDA REGULATION
Any federal food-related insect regulation falls to the FDA. The bulk of the rules pertain to keeping bugs out of food–mostly anyways. The agency oversees Food Defect Action Levels, or the unavoidable amount of insects that end up in food such as chocolate or peanut butter.
The FDA does allow crickets to be used for and in food, under the Food, Drug, and Cosmetic Act (Sec. 201(f)). As long as crickets are produced, packaged, stored and shipped in a clean and wholesome way, the FDA allows production and sale. Insects must be raised for the purpose of food, and not caught in the wild. The final label must also include the scientific name of the insect.
Cricket flour is not GRAS certified by the FDA. However, the agency has made no ruling against it and it is still legal for commercial sale. According to the FDA, “a substance is excepted from regulation as a food additive if the substance is generally recognized to be safe (GRAS), among qualified experts.”
