Abstract:
More than 300 groundnut (peanut) samples collected from different regions of Israel were examined by ELISA for aflatoxin contamination. Samples were designated for export, local consumption or for sowing. None of the samples were contaminated with the toxin. However, when kernels were kept at high humidity (RH≊99%), aflatoxin could be frequently detected seven days after incubation and the toxin was not uniformly distributed among kernels. Aspergillus niger, A flavus, Penicillium citrinum and P pinophilum were the dominant fungi and no differences were observed among cultivars. Almost half of the commercial samples examined were devoid of A flavus. Other fungi identified were A tamaril, A amstelodami, P rubrum, Rhizoctonia solani, Macrophomina phaseolina, Rhizopus spp., Sclerotium rolfsll, Fusarium and Alternaria spp; the two last ones comprising a group of low incidence. Although groundnut samples that contain A flavus-infected kernels are moderately common, the local climate and agrotechniques In use in Israel are not conducive to aflatoxin accumulation. Nevertheless infected kernels may become a threat to health if stored under inadequate conditions. © 1994 Society of Mycotoxin Research and Springer.
