PURPOSE: to characterize the auditory and vestibular symptoms of rural workers under an environmental exposed of organophosphate pesticides. METHODS: this is a descriptive epidemic study that evaluated 50 workers. The age group varied from 21 to 59 years with a mean age of 38.3 years. There were 20 (40%) male and 30 (60%) female workers. A questionnaire was used with questions related to the auditory health in addition to some specific questions on time exposure. RESULTS: the results showed that 38 (76%) workers showed dizziness and 29 (58%) of them continued showing these symptom; 27 (54%) related tinnitus; 23 (46%) fullness sensation. 37 (74%) workers don't have problem with hearing but 35 (70%) can't understand very well the spoken words. Data suggest that the pesticides induce auditory and vestibular system alterations. It is possible to affirm that it is a slow, insidious and silent intoxication. CONCLUSIONS: dizziness and hearing loss are a constant and subclinical symptoms in occupational exposure suggesting a precocious intoxication signal, harming the quality of life of these workers.
