✦ Synopsis

A total of 126 fungal strains belonging to the Aspergillusflavus group isolated from commercial poultry mixed feeds were studied. One hundred and twenty-five were identified as A. flavus and one as A. parasiticus.

Forty nine strains (39%) produced aflatoxins on a crushed moist wheat medium (28 ~ days), whereas only sixteen (13%) showed specific fluorescence on Aflatoxin-Producing Ability Medium. In both media, mainly aflatoxins B 1 and B2 were detected, the average concentration of aflatoxins being 4294 +/-1083/zg/kg in crushed moist wheat medium, and 877 +/-257 tzg/kg in Aflatoxin-Producing Ability Medium.
