Fish and fishery products are healthy and nutritious and are important in the food and livelihoods of millions of people around the world. However, if they are not handled and processed properly, they can pose a risk to consumer health. Some fish and shellfish may contain high concentrations of industrial pollutants, such as heavy metals and polychlorinated biphenyls (PCBs). And the use of agricultural pesticides to fight against the infestations of plants and animals. Consequently, standards fixing the maximum residue limits have been established. It exists several analytical methods able to identify and quantify pesticides at very low concentrations. The objective of our study is to develop a modified "QuEChERS" analytical method for detecting and quantifying organochlorine pesticide residues in bivalve by changing the extraction solvent and validating his validation criterions (fidelity, limit of detection, limit of quantitation, reproducibility, linearity ...). This method can then be applied to many types of bivalves after appropriate treatment.
