Determination of mycotoxins in pet foods sold for domestic pets and wild birds sing linked-column immunoassay clean-up and HPLC

摘要

A technique referred to as 'linked-column immunoassay clean-up', as developed for the simultaneous determi- nation of aflatoxins and ochratoxin A in a range of dry cereal-based pet foods and wild bird food. In addition a method also based on clean-up using immunoaffinnity columns was used for the determination of fumonisin mycotoxins in samples known or suspected to contain maize. One hundred samples of pet foods consisting of 35 samples each of cereal-based dog and cat foods, 15 samples of domestic bird seeds and 15 samples of wild bird food were examined for aflatoxins B_1, B_2, G_1 and G_2 and ochratoxin A.
