Preservative chemicals as a new health risk related to traditional medicine markets in western Africa.

ABSTRACT

Health risks associated to the use of tropical wildlife have so far been envisioned through the lens of zoonotic pathogens spread by the bushmeat trade, putting aside the equally vibrant network of traditional medicine markets (TMMs). We collected information on the preservative techniques used for animal body parts from TMMs in Benin through a semi-structured questionnaire addressed to 45 sellers. We show that a recent shift from traditional preservative techniques using harmless treatments towards modern techniques -involving the recurrent use of hazardous chemicals (such as Sniper)- is likely to pose a serious health risk to practitioners and consumers of animal parts from TMMs in Benin. We conclude that the non-regulation of the TMM activities represents a critical risk to both biodiversity conservation and human health in western Africa.
