If you thought finding a fly in your soup was enough to turn you off your meal, try finding a maggot in your canned mushrooms or caterpillar remains in your spinach salad. Just about everyone has heard a horror story when it comes to food and insects, and part of that might be thanks to relaxed policies when it comes creepy crawlers and governmental food agencies.

In the United States, the Food and Drug Administration (FDA) is the body overseeing the protection of public health by assuring the safety and security of food consumed in America. However, due to what's described as by Organic Gardening as "a lax food-safety loophole," the FDA permits a certain degree of insects, such as worms or aphids, so long as their presence doesn't compromise the aesthetic quality of the food.

The Canadian Food Inspection Agency has some rules about labels when it comes to bugs and food with which produce can be sold. For example, for cabbage, 10 aphids on a head can still equal a no.1 grading during inspection, but any presence of worms on an edible portion of the head bumps a crop down to a no.2 grading.

Here's a compilation of the eight bugs you might be unintentionally eating according to the FDA's "The Food Defect Action Levels: Levels of natural or unavoidable defects in foods that present no health hazards for humans" guide. Story continues below:
