Why is a wide margin of safety included in regulations regarding pesticide residues?

1. To make pesticides cheaper for farmers

2. To ensure residues are lower than harmful levels

3. To comply with international standards

4. To promote the use of more pesticides

The correct answer is: To ensure residues are lower than harmful levels

A wide margin of safety is included in regulations regarding pesticide residues primarily to ensure that the levels of these residues remain well below any potential harmful thresholds. This practice is grounded in the precautionary principle, where the health and safety of the public and the environment are prioritized over the economic implications of pesticide use. By establishing a significant buffer in allowable residue levels, regulatory agencies aim to minimize exposure risks to humans and non-target organisms. This approach guarantees that even if there are uncertainties about the long-term effects or resistance issues associated with pesticide residues, consumers and the environment are protected from possible negative impacts. The intention is to promote food safety and public health by ensuring that agricultural practices do not lead to harmful exposure levels, which can result from either direct consumption or accumulation in the ecosystem. While compliance with international standards and other economic considerations are important, the core reason for a wide margin of safety is to protect human health and the environment by maintaining pesticide residues below harmful levels. Thus, the focus is on safety rather than cost or promotion of pesticide use.
