As a food safety expert, I can tell you that the Food and Drug Administration (FDA) in the United States has guidelines on the allowable levels of natural defects in food, including chocolate. These guidelines are part of the FDA's broader food safety regulations and are designed to ensure that food products are safe for consumption while also recognizing that some natural defects are unavoidable in the production process.

According to the FDA's Defect Levels Handbook, for chocolate, the "action level" for insect fragments is **not more than 60 insect fragments per 100 grams** of chocolate. Similarly, the action level for rodent hairs is **not more than 1 rodent hair per 100 grams** of chocolate. It's important to note that these levels are not considered to represent safe or acceptable levels of contamination. Instead, they are **levels at which the FDA may take regulatory action** if exceeded.
