The warm weather and high relative humidity in Malaysia are ideal for the survival and proliferation of mycotoxigenic fungi leading to a high rate of stored product contamination. This study was conducted to enumerate and characterise the mycotoxigenic fungi associated with commonly consumed food grains in Kelantan Malaysia. The fungal bioburden and fungal identification from forty-four composite food samples comprising 11 samples each of maize wheat rice and peanuts from open markets in Kelantan Malaysia were determined using standard mycological techniques. A total of 115 mould fungal isolates belonging to 12 species were isolated of which Aspergillus flavus (17.39) A. versicolor (13.04) A. felis (12.17) Neoscytalidium dimidiatum (11.3) Penicillium cheresanum (11.3) and P. chrysogenum (8.7) were predominant. Peanuts were the most contaminated (9.710� 1.510� CFU/g) followed by maize (7.510� 1.810� CFU/g) wheat (1.910� 2.610� CFU/g) and rice (9.910�´ 1.510� CFU/g). The levels of the mycotoxigenic fungi in peanut maize and wheat were above the permissible limit of 102 CFU/g set by the Malaysian Ministry of Health and 10 to 10� CFU/g set by the International Commission for Microbiological Specification for Foods signifying that they are unsafe for use as food or feed ingredients. Hence there is a need for more stringent control measures.

Abstract

The warm weather and high relative humidity in Malaysia are ideal for the survival and proliferation of mycotoxigenic fungi leading to a high rate of stored product contamination. This study was conducted to enumerate and characterise the mycotoxigenic fungi associated with commonly consumed food grains in Kelantan Malaysia. The fungal bioburden and fungal identification from forty-four composite food samples comprising 11 samples each of maize wheat rice and peanuts from open markets in Kelantan Malaysia were determined using standard mycological techniques. A total of 115 mould fungal isolates belonging to 12 species were isolated of which Aspergillus flavus (17.39) A. versicolor (13.04) A. felis (12.17) Neoscytalidium dimidiatum (11.3) Penicillium cheresanum (11.3) and P. chrysogenum (8.7) were predominant. Peanuts were the most contaminated (9.710� 1.510� CFU/g) followed by maize (7.510� 1.810� CFU/g) wheat (1.910� 2.610� CFU/g) and rice (9.910�´ 1.510� CFU/g). The levels of the mycotoxigenic fungi in peanut maize and wheat were above the permissible limit of 102 CFU/g set by the Malaysian Ministry of Health and 10 to 10� CFU/g set by the International Commission for Microbiological Specification for Foods signifying that they are unsafe for use as food or feed ingredients. Hence there is a need for more stringent control measures.
