Mexico is an agriculturally important country with limited biomonitoring data. High pesticide use in horticultural productivity leads to environmental contamination and risks to workers' health. The study shows that horticulturists have significantly higher genetic damage compared to unexposed controls, indicating the need for protective measures and educational programs to prevent health risks.
Mexico is a country where agricultural activity is of great importance, but biomonitoring data are still scarce. With more intensive pesticides use per unit area/surface in horticultural productivity, there is a higher impact on environmental contamination and workers' health. Considering that exposure to various pesticide and pesticide mixtures represents an additional genotoxic risk, the appropriate characterization of exposure, confounding factors and the risk itself are very much needed. We compared genetic damage in 42 horticulturists and 46 unexposed controls (Nativitas, Tlaxcala) using alkaline comet (whole blood) and micronucleus (MN) test with nuclear abnormalities (NA) (buccal epithelial cells). Workers demonstrated significantly higher levels of damage (TI%=14.02 +/- 2.49 vs. 5.37 +/- 0.46; MN=10.14 +/- 5.15 vs. 2.40 +/- 0.20), with more than 90% of them not using protective clothing nor gloves during application. Combined DNA damage techniques and periodic monitoring together with educational programs for safe pesticide application is the best strategy to assess and prevent workers' health risks.
