Samples of the 1972 corn crop were collected in areas where the potential for Fusarium contamination of the corn was considered to be high or where known Fusarium damage had been reported. The 223 samples were collected in the spring following the crop year from terminal elevators or from stocks on hand at food processing establishments and were analyzed for zearalenone, anatoxins, and T-2 toxin by a modified multimycotoxin detection method. A rabbit skin bioassay was used to screen for possible T-2 toxin at levels below the chemical detection limits. Zearalenone was found in 17% of the samples (0.1-5.0 mg/kg); anatoxin was found in 5 samples (trace-10 μg/kg). A skin irritant was found in extracts from 93 of 173 samples by the rabbit skin bioassay. This effect may be due to the T-2 toxin or some other mycotoxin.
