Abstract

Oilseed chain professionals are coordinated through a food safety survey plan, in order to have a realistic picture of contaminations in oilseed products. Pesticide residues are found in seeds and crude oils: they are mainly organophosphate insecticides (pirimiphos-methyl, dichlorvos, malathion) used for empty storage premises treatment and for stored cereal grains treatment. Even if studies showed that pests can be found in stored oilseeds, French regulation does not authorize these insecticides on stored oilseeds, which have however an affinity for liposoluble chemicals and can pick these up from storage environment. This uptake of insecticide residues by oilseeds from their storage environment can lead to levels that can exceed regulatory limits. Works are in progress in order to improve and standardize analytical methods for pesticide residues in oilseeds and oils.
