Gross Bugs Allowed in Your Food - as part of the news and politics series by GeoBeats.

While most of us are disgusted by a tiny bug we may see in our salad, we all still probably consume small bits of maggots and other insect fragments in our food. That's because the FDA allows certain level of contaminations as it's not possible to grow and process food products, completely free of impurities. Here are some examples:

- Peanut butter - the FDA will not take action unless there's an average of 1 or more rodent hair per 100 grams.

-Canned mushrooms - the FDA will not take action unless there's an average of over 20 or more maggots of any size per 100 grams of drained mushrooms and proportionate liquid.

- Ground oregano has to have less than 1250 insect fragments per 10 grams.

- Sesame seeds - the FDA takes action if average of 5% or more seeds by weight are insect-infested or damaged.

- Canned tomatoes - Average of 10 or more fly eggs per 500 grams will initiate an action by the FDA.

- Tomato juice must not have average of 10 or more fly eggs per 100 grams.

- If wheat flour has average of 1 or more rodent hair per 50 grams, it will provoke action by the FDA.

According to the FDA, impurities upto these levels do not pose any health hazards and that the actual averages are much lower.
