How many pieces of insect are in the average chocolate bar?

The answer is: around 8.

Explanation:

According to the Food and Drug Administration (FDA), chocolate manufacturers producing over 10,000 bars a year are allowed to have an average of 60 insect fragments per 100 grams (about a third of a standard-size chocolate bar). Manufacturers producing fewer bars a year are allowed up to 90 fragments per 100 grams of chocolate. Since a standard-size chocolate bar weighs around 45 grams, this means there are, on average, between 2.7 and 4 insect parts in every regular-size chocolate bar. However, these fragments aren’t whole insects; they’re just body parts, such as legs, wings, and antennae. So while there may be around 8 insect fragments in the average chocolate bar, it doesn’t mean there’s a whole bug in there.
