Potential Residual Pesticide Consumption: A Stratified Analysis of Brazilian Families

Food safety is essential to ensure that food is safe for human consumption, particularly in light of the growing global and environmental changes, including population growth and climate variations. Meeting the increasing demand for food requires enhancing and protecting agricultural systems. A common strategy is the use of pesticides, which serve to protect cultivated plants from pests, diseases, and weeds. However, improper and excessive use of these products can lead to negative impacts, spanning economic, environmental, and human health aspects. Concerns about pesticide residues in food are global, as their effects on human health vary depending on exposure and quantity. The main objective of this study was to estimate the potential residual consumption (PRC) of pesticides present in food consumed by Brazilian households. Using a specific methodology, it was identified that pineapple had the highest average PRC (121.01 mg), primarily due to the high residue of the active ingredient ethephon. On the other hand, Dithiocarbamates showed the highest residual quantity. Tebuconazole was the most repeated in the samples. It was observed that the insecticide class was responsible for the highest average PRC in households, estimated at 142.45 mg annually, while higher-income families and those located in rural areas showed a greater propensity for potential residual pesticide consumption due to the higher consumption of fruits and vegetables. Additionally, it was found that households where the head of the family is male, highly educated, and older than 40 years present a higher risk of potential residual pesticide consumption. These results highlight the need for public policies focused on sanitary inspection, the training of professionals in the field, the rational use of pesticides by producers, and proper hygiene practices by consumers to mitigate health risks.
