Abstract: This work aims to explain the factors that facilitate aflatoxins contamination in the peanut sector in Haiti. The results obtained from by literature review, observations and interviews with actors in North and North-East areas of the country have revealed several practices favorable to the contamination of products such as : lack of crop rotation, early or late harvest, inadequate drying and storage, poor rigor in peanut selection during and after harvest. Other harmful practices such as wetting peanut and uncontrolled or even deliberate mixing of good and poor-quality peanuts substantially increase the risk of contamination during marketing. Aflatoxin test results on some products showed high rates ranging from 22 ppb to 36 864 ppb in 55 out of 100 field-collected samples, indicating the serious quality problem in the chain. Several factors sustaining the bad practices and product contamination were analyzed. Dimensions are organizational, socio-economic, institutional, political, technological and environmental. We have thus been able to build a systemic diagram that shows how these multiple factors combine to lead practices that strengthen aflatoxins contamination and provided paths of intervention for improving products quality in the commodity chain.
