A method based on solid phase extraction followed by derivatization and gas chromatography–mass spectrometry analysis was validated for the determination of bisphenol A (BPA) in canned food products. This method was used to analyze 78 canned food products for BPA. Concentrations
of BPA in canned food products differed considerably among food types, but all were below the specific migration limit of 0.6 mg/kg set by the European Commission Directive for BPA in food or food simulants. Canned tuna products had the highest BPA concentrations in general, with mean and
maximum values of 137 and 534 ng/g, respectively. BPA concentrations in the condensed soup products were considerably higher than those in the ready-to-serve soup products, with mean and maximum values of 105 and 189 ng/g, respectively, for the condensed soups and 15 and 34 ng/g, respectively,
for the ready-to-serve soups. BPA concentrations in canned vegetable products were relatively low; about 60% of the products had BPA concentrations of less than 10 ng/g. Canned tomato paste products had lower BPA concentrations than did canned pure tomato products. The mean and maximum BPA
concentrations were 1.1 and 2.1 ng/g, respectively, for tomato paste products and 9.3 and 23 ng/g, respectively, for the pure tomato products.
