This article focuses on the economic and biotechnical consequences of changes in the legal maximum residue limits for pesticides (here chlordecone) on meat production. We model the concentration of this persistent pollutant in livestock meat in the French Antilles and analyse the link between soil pollution, animal contamination and food production. We compute the time length and the cost of decontamination and analyse if it is possible to respect both the health constraints and the current livestockmanagement schedule. We compute the cost for farmers to adapt to the new regulation and the possibility to comply with more stringent healthrelated targets
