Pesticide use is intensive in Brazilian agriculture. Population-based studies on the characteristics of pesticide use and pesticide poisoning are scarce. This study describes the profile of occupational exposure and pesticide poisoning incidence. Farm characteristics and pesticide occupational exposure were evaluated using a cross-sectional design. Among 1,379 farmers/farm workers, annual incidence of pesticide poisoning was 2.2 episodes per 100 exposed. Based on Poisson regression, applying pesticide, reentering crop fields after spraying, and working with pesticides on more than one farm were the types of exposure that presented a positive correlation with pesticide poisoning. The results may be useful for planning activities aimed at reducing occupational pesticide poisoning among rural workers.
