Structural Pest Control Applicator Practice Exam

What margin of safety ("safety factor") does the EPA use to set tolerances?

1. 10 times.

2. 100 times.

3. 1,000 times.

4. 5 times.

The correct answer is: 100 times.

The Environmental Protection Agency (EPA) applies a safety factor of 100 times when setting tolerances for pesticide residues. This means that the EPA establishes limits on the amount of pesticide residue that can be present on food or feed products based on a risk assessment that includes this significant margin of safety. This precautionary approach ensures that even the most vulnerable populations, such as children, are protected from potential health risks associated with pesticide exposure. By incorporating such a substantial safety factor, the EPA seeks to account for uncertainties in the toxicity data and variations in individual susceptibility. This is crucial for fostering public confidence in pesticide regulations and ensuring that the health of consumers is prioritized in the regulatory framework.
