RESUMO

Aflatoxins were produced on fresh beef (in which bacterial spoilage was delayed with antibiotics), ham, and bacon inoculated with toxinogenic fungi and stored at 15, 20 and 30 C. Meats stored at 10 C were spoiled by bacteria and yeast before detectable levels of aflatoxins were produced. High levels of aflatoxins were formed in meats stored at 20 C; one sample supported the production of 630 μg of aflatoxins per g of meat, the major portion (580 μg) of which was aflatoxin G1. Meats stored below 30 C developed higher levels of aflatoxin G1 than B1, but at 30 C Aspergillus flavus produced equal amounts of B1 and G1, whereas A. parasiticus continued to produce more G1 than B1.
