||Object ive: To assess the degree of poisoning in farmers using the erythrocyte acetylcholinesterase (AChE) test before and after the
exposure to pesticides in townships in central Benin (Glazoué and Savè) and to identify the associated risk factors.
Methods: Using a cross-sectional study design, we recruited 264 farm pesticide sprayers, who have been working for at least 5 years.
They completed a questionnaire and underwent the AChE test using the Test-mate Model 400 device (EQM Research Inc.) with a photometric
sensor, based on the works of Ellman.
Results : Organophosphate/pyrethroids were the most common pesticides used by at least 72.96% of the farmworkers. We observed an
inhibition of AChE between pre-exposure and post-exposure (P = .002) for 60.61% of the farmworkers. Among them, 11.88% displayed more
than 20% AChE inhibition.
Conclus ions: Pesticide poisoning is a reality, and AChE monitoring is urgently needed for farmworker surveillance.
