ABSTRACT

Mycotoxins are toxins produced by aspergillus, a type of fungus that can be found virtually everywhere and their toxicity occurs at very low concentrations. For good storage condition of the post-harvest grains, the sensitive and reliable methods for detecting mycotoxins are required for long-term sustainability of animals ingesting excessive amounts of the toxin from chronic health problem to death. The aspergillus grows rapidly in the air with high relative humidity contrast to the air with low relative humidity. In this study, the samples of maize were randomly collected in three sectors: Nyamata, Gakenke and Mahembe. Using selective media and biochemical tests, the three strains; A. flavus, capable of producing both B- and G-type aflatoxin and A. pseudotamarii which has not previously detected in our region and A. parasiticus, isolated from the collected maize and the total aflatoxin (AFT) in maize flour was evaluated by Reveal Q+; the mean concentrations of AFT were 52.3±3.93 CFU/ml for Mahembe sector, 49.5±0.98 CFU/ml for Gakenke sector and 43.7±2.15 CFU/ml for Nyamata sector. The level of AFT contamination in a, b, c sectors was higher than the maximum tolerable limit of aflatoxins recommended by the United States Food and Drug Administration guidelines for aflatoxin in animal feeds and human foods at 20 parts per billion (20 ppb).
