Any food containing animal feces is an automatic fail, which is why imported spices is at the top of our list.

According to the Food and Drug Administration (FDA), 12 percent of the United States' imported spices are contaminated with things like rodent hair, insects parts, whole insects and salmonella.

After three years of research on imported spices, the FDA released a report stating that they found that 6.6 percent of imported spices were contaminated with salmonella, which was 1.9 times more than other FDA-regulated imported foods during the time of study. Insect parts were found twice as much in imported spice as in other imported food.

During the three-year-long study, the FDA sent back 749 shipments of spice because of salmonella contamination. In addition, 238 shipments were refused because of "filth," which includes live and dead whole insects and insect parts, animal, bird and insect excrements, sheep, dog, cat, rodent, bat and other animal hair and additional nastiness like rubber bands, bird feathers, staples, stones, twigs, plastic and synthetic fibers.

Michael Taylor, deputy commissioner for foods at the FDA, told Fox News that there was no need to stop eating spices. Jane M. Van Doren, a food and spice official at the FDA, told The New York Times that spice contamination is a "systemic challenge" most likely caused by poor processing and storage methods.

A little spice is always nice, but, please, hold the insect parts.
