Pesticides exposure in Culturama, Brazil--knowledge, attitudes, and practices

In this study, the knowledge, attitudes, and practices associated with pesticide use and exposure were evaluated in the agricultural community of Culturama, in the state of Mato Grosso do Sul, Brazil. A standardized questionnaire was completed by 250 farm workers aged > or =18 years old. The average age of the studied population was 43.6 years and 17.6% had never been to school. Their farms were small (approximately 30ha) and family operated and did not utilize advanced farming technology. About 92% of the interviewees had worked directly with pesticides and 59.6% reported typical intoxication symptoms. Only 44.3%, however, believe that they had been intoxicated. A significant correlation was found between hand washing after pesticide application and reporting symptoms (P=0.014). Over 90% of the farmers reported using the organophosphorus insecticide methamidophos. A great majority (>90%) considered pesticides to be harmful to human health, but less than 20% used masks, impermeable clothes, or gloves during pesticide application. These results indicate that special educational programs, legislation promoting the use of safer pesticides, and implementation of personal protective measures are necessary to decrease the pesticide exposure of farmers in Culturama.
