SUMMARY:

Brazil is the largest consumer of pesticides in the world and its food production is dominated by agribusiness, a fact that consequently increases the use of pesticides in agriculture, with harmful effects on food systems, health, and the environment. The available data on chronic exposure to pesticides is limited, posing challenges in accurately assessing the true impact of these compounds on human health. The estimation of pesticide residue intake through food can be a tool to enhance the role of nutritionists in food services and assist in planning healthy and sustainable menus. The objective of the study was to evaluate the risk of exposure to pesticides in foods offered on menus in institutional food and nutrition units. The crosssectional, quantitative, and descriptive research analyzed 120 lunch menus, from 06 institutional restaurants, regarding the permission of active ingredients (AI) of pesticides in the foods offered, toxicological, agronomic characterization and bioaccumulation potential, in addition to the risk of exposure chronic. To evaluate the pesticides authorized in the country for use in food, data on Maximum Residue Limit (MRL) and Acceptable Daily Intake (ADI) were collected from the Pesticides monographs of the National Health Surveillance Agency - ANVISA and the Codex Alimentarius base. To analyze the estimated Theoretical Maximum Daily Intake (IDMT), the calculation was carried out according to the relationship between the MRL of the pesticide and the per capita quantity of the food. The IDTM was expressed in mg/kg of body weight and compared with the ADI to assess the risk of exposure. Maximum daily intake estimates were calculated considering the lunch meal and 263 active ingredients were identified, 43% insecticides, 40% fungicides, 14% herbicides, 1% nematicides and 1% acaricides, authorized for use in 40 foods. Of the residues possibly most present in the foods offered on menus, 4% are extremely toxic, 5% highly toxic and 14% moderately toxic to health. The analysis identified 42 compounds with high potential for bioaccumulation, especially those authorized in foods of animal origin. The presence of multiple pesticide residues was found in a single food, with rice, beans, wheat, potatoes, tomatoes, milk, and ultraprocessed sauce being everyday foods with the highest number of permitted pesticides. To estimate daily intake, AIs such as 2,4D, acephate, bifenthrin, carbaryl, methomyl, cypermethrin, chlorothalonil, chlorpyrifos, glyphosate, imidachlorpid, tebuconazole and terbufos were analyzed. Our findings indicate that 99% of the active ingredients possibly present in foods are within the acceptable ADI range, however, they warn of the toxic, synergistic and cumulative effects of these substances. The insecticide methomyl possibly presented an unacceptable risk of ingestion only during the lunch meal, with average IDMT values of 0.264 mg/kg of body weight. It is concluded that there is chronic exposure to pesticides through food, particularly methomyl in beans and rice. The data reinforces the importance of monitoring pesticides in food, as well as the need for changes in food production methods to promote the acquisition of healthier and safer food for collective consumption.
