Comparison among three screening methods for aflatoxigenic isolates.
Seventy-six isolates of Aspergillus flavus, which were isolated from one hundred food stuffs in Zhejiang Province, were detected with RMC, AMCS and APA methods for aflatoxigenicity. The rates of toxigenic isolates detected by the three methods were 11.8%, 18.4% and 9.2% respectively. There were twenty toxigenic isolates detected by the three methods (26.3%) AMCS method was better than other methods. False negatives appeared in all methods. False positive appeared in both AMCS method and APA method. It was suggested that AMCS method may be a safe, simple and reliable method for screening toxigenic isolated if some aspects were improved.
