Why are tolerances set for pesticide residues?

Tolerances for pesticide residues are set primarily to ensure food safety and prevent excessive pesticide residues on food products. These tolerances define the maximum amount of pesticide residue that is permissible in or on food items and are established based on rigorous scientific assessments of potential health risks to consumers. Regulatory agencies evaluate factors such as toxicity, exposure levels, and the effects of long-term exposure to these substances.

Establishing such tolerances is critical for protecting public health, as it helps to ensure that the food supply remains safe for consumption. By setting these limits, authorities can effectively monitor and regulate pesticide use, ensuring that farmers and food producers apply these chemicals responsibly and in accordance with safety guidelines.

The other options do not align with the primary purpose of establishing tolerances. While increased sales and minimizing production costs may be outcomes of pesticide use, they do not address the core concern of safety. Similarly, avoiding regulatory actions may be a consequence of compliance but is not the foundational reason for setting tolerance levels.
