| Popis: | Between March 1998 and March 2002, 304 samples of domestic (Canadian) and imported beers from 36 countries were picked up for the determination of aflatoxins B1 ,B 2 ,G 1 and G2. Twelve samples were positive with aflatoxins greater than the limit of quantitation (LOQ) (aflatoxin B1, 4.4 ng l � 1 ; aflatoxin B2, 3.4 ng l � 1 ; aflatoxin G1, 11.2 ng l � 1 ; and aflatoxin G2, 6.2 ng l � 1 ). Five samples from Mexico, two samples from Spain and one from Portugal contained aflatoxin B1. Four samples from India contained aflatoxins B1 and B2. The remaining samples contained less than the LOQ for aflatoxins B1 ,B 2 ,G 1 and G2. The analytical method for this survey was based on that of Scott and Lawrence (Scott PM, Lawrence GA. 1997. Determination of aflatoxins in beer. Journal of AOAC International 80:1229–1234.). Aflatoxins B1 ,B 2 ,G 1 and G2 were determined at parts per trillion (ng l � 1 ) levels in beer by immunoaffinity column cleanup followed by derivatization with trifluoroacetic acid and reversed-phase liquid chromatography with fluorescence detection. |
