Mycoflora and Natural Occurrence of Mycotoxins in Some Meat Products and Livers of Poultry and Imported Bulls
A.-L. E. Mahmoud, A. M. Sayed and A.A. Abou El-Alla

Abstract: Mycological analysis of local meat products (luncheon and minced meat) and livers of poultry and imported bulls resulted in isolation of 29 fungal species related to 10 genera. The average total counts of fungi per gram fresh weight ranged from 2680 in luncheon to 7460 in livers of poultry. Aspergillus was the most prevalent genus followed by Penicillium where they were isolated from all the examined substrates. Many of the isolated fungi might have mycotoxin-producing potential. Results of mycotoxins analysis revealed that, 45% of the examined samples were positive. Aflatoxins (B1, B2, G1 and G2), ochratoxin A, citrinin and sterigmatocystin were detected. Samples of livers from imported bulls contained the highest levels of aflatoxins and ochratoxin A (54 and 145 μg/kg, respectively). The majority of the remaining mycotoxin contaminated samples contained a high level which was far above the acceptable ones. The hazardous effects of these natural pollutants were discussed.
