To evaluate the acetylcholinesterase level and risk factors of poisoning in pesticide users in cotton production areas in Benin. Using a cross sectional study design, 454 individuals who have been working as pesticide sprayers for at least 5 years were recruited. They completed a questionnaire and underwent AChE test before and after pesticide spraying using the Test Mate® model 400 devices (EQM Research Inc) with a photometric sensor. Empty pesticide containers/packagings were either burnt (32.82%) or re-used for domestic purposes (15.20%). After spraying, 47.93% of the participants consume milk believing that it is a good precaution against poisoning. Only 21.13% systematically use Personal Protective Equipment (PPE) while spraying pesticide. There was a significant inhibition between pre-exposure (AChE 2.92 ± 1.56 UI / ml) and post-exposure (AChE 2.73 ± 0.61 IU / ml): p = 0.01) AChE levels in the participants. AChE inhibition was higher in farmers who do not use PPE than in others (p=0.04).Pesticide poisoning is a reality therefore training and more preventive precaution should be taken and AChE monitoring is urgently needed for farm worker surveillance.
