Major types of internal can coatings used for food and beverages are made from synthetic polymers known as epoxy-based resins, mainly based on bisphenol A diglycidyl ether (BADGE). The migration of components from coatings to food is a concern for food safety. A multiresidue method was developed for the identification and quantification of six bisphenols, BADGE and its derivatives, and cyclo-di-BADGE in sixteen canned food samples based on HPLC-FLD. The method developed showed excellent validation data with an adequate linearity, low detection levels, good repeatability and acceptable recoveries. Confirmation of the obtained results was made by LC–MS/MS. The exposure of the adult population to these compounds through the consumption of canned food was assessed. In general, the results suggested a low dietary exposure to this type of compounds (0.003 to 0.985 μg/kg bw/day) with values lower than the established tolerable day intake (TDI). The highest mean concentration was observed for cyclo-di-BADGE in a sample of pickled mussels.
