Working conditions and practices with pesticides in vector control workers in Mexico

Abstract

In Mexico, organophosphorus, carbamates and pyrethroid pesticides are used as part of the program for the control of diseases transmitted by the Aedes aegypti mosquito. Therefore, sprayer operators represent one of the populations with a higher risk of occupational exposure to these compounds. This study aimed to analyze the working conditions that increase the opportunity for pesticide exposure in workers employed in the program to control the adult A. aegypti mosquito in the state of Morelos, and how these conditions shape the work habits and their safety practices. We performed a qualitative study on the Health Services of Morelos workers involved in the vector-borne diseases control program. Data was obtained through focus groups and ethnographic records during April and May 2014. According to the gathered information from participants, the work environment and precarious working conditions modulate risk behaviors in pesticide handling by representing concrete barriers that hinder the adoption of safety measures. Hence, it is imperative to create working conditions aimed at reducing the incidence of pesticide exposure in health workers who perform chemical control of vector-borne diseases.
