Abstract

A review of pesticide residues detected in shrimp species of the Mexican Pacific and Gulf of Mexico coasts is presented. Most studies focus on monitoring organochlorine (OC) and organophosphate (OP) pesticides. The evaluated areas are mainly located in the northwestern zone of Mexico. Studies analyzing pesticides levels in shrimp of Mexico correspond to commercially important species, such as: Penaeus vannamei, Penaeus stylirostris, Farfantepenaeus duorarum, and Trachypenaeus similis pacificus. Extraction methods (sample preparation, extraction technique, solvent, and clean-up procedures) are presented, as well as chromatography and detector type used to quantify the analytes in the shrimp samples from the different ecosystems evaluated. Given that there is an under-evaluation of pesticides residues presence, there was a greater contribution of studies directed to geographical areas in the northwest of the country, with a monitoring gap in the Gulf of Mexico, as well as in the southern zone, considering that there are states that are among the main shrimp-producing entities. Hence, it is necessary to carry out recent evaluations, since the most current information is 17 years out of date, so presented data may not be a reflection of the current situation in the country.
