Abstract

The mycotoxins 4-deoxynivalenol, zearalenone and aflatoxin in weather-damaged wheat harvested 1983-1985 in south-eastern Queensland.

Abstract

In Queensland, Australia, a survey for mycotoxins was carried out on wheat samples from 9 selected storage and marketing depots. Deoxynivalenol was detected in nearly all pooled samples at concentrations from 0.01 up to 1.7 mg/kg. The highest concentration of zearalenone detected in a pooled wheat sample was 0.04 mg/kg. In a few samples from individual wheat deliveries, up to 2.8% of pink grains, 11.7 mg/kg of deoxynivalenol [vomitoxin] and 0.43 mg/kg of zearalenone were detected. Aflatoxins were only detected in 1 pooled sample, at a total concentration of 0.003 mg/kg. The higher concentrations of mycotoxins were found in the poorer grades of wheat. From authors' summary.
