Aflatoxin survey of maize from the 1978 crop in the South Burnett region of Queensland

Abstract

A rapid screening test was applied to 805 samples from the 1978 maize crop in Queensland. Of 140 samples selected as positive by the test, aflatoxins were detected in 15 samples in which average levels were 0 · 045 mg kg-1 total aflatoxins B1 B2 G1 and G2. Of 70 samples chosen at random from the remaining 665, only two contained detectable levels, averaging 0·007 mg kg-1 total aflatoxins.
