Abstract

AFLATOXINs are the toxic secondary metabolites produced by ASPERGILLUS FLAVUS and related fungi in foods such as GROUNDNUT. They are carcinogenic, mutagenic, teratogenic and immunosuppressive agents that cause adverse affects on human and animal health. In this study 156 GROUNDNUT samples collected from markets in Northern provinces of Iran (Gilan, Mazandran and Golestan) were examined for AFLATOXIN B1 concentration (mg/kg) by indirect competitive enzyme-linked immunosorbent assay (ELISA), and A. flavus seed infection in GROUNDNUTs was determined by blotter plate method. This revealed A. flavus seed infection in 58.23%, 46.67% and 36.9% of GROUNDNUT samples collected from Golestan, Mazandran and Gilan, respectively, with the percent seed infection between 8 and 100%. Only one sample conatined 491 mg/kg of AFLATOXIN and in the remaining samples the toxin concentration was within the acceptable limit of 5mg/kg. There was no significant variation in toxin concenration (P>0.05) between GROUNDNUT samples collected from different provinces. There was no significant difference in A. flavus seed infection in samples from Golestan and Mazandran (P>0.05), but there was significant difference in samples from Gilan with samples from Golestan and Mazandran (P<0.05). This study revealed high A. flavus seed infection in GROUNDNUT samples from markets, but AFLATOXIN concentration was within the limits in most of the samples probaly due to unfavorable conditions for toxin production. However, seed predisposed to A. flavus poses potential risk for high AFLATOXIN contamination under congenial storage conditions.
