Background and Objectives: Contamination of storage wheat to zearalenone producer molds represents a
significant hazard to consumer health and has thus received increasing attention from food safety authorities
and legislators. Various species of Fusarium genus are producer of different mycotoxins including
zearalenone at certain conditions. These mycotoxins can enter into the human food and animal feed chain
and cause premature or early thelarche, gynecomastia, primary and secondary mycotoxicosis in humans and
animals.
Materials and Methods: In this survey, contamination of 162 randomly collected wheat samples to
zearalenone producer Fusarium was investigated using direct microscopic examination and culturing
samples in specific media.
Results: From studied 162 collected wheat samples, 160 (99%) samples had fungal contamination.
Aspergillus niger, Penicillium Sp, other species of Asergillus (A. Fumigatus, A.Flavous, A. Mʹveus, A.
cchraceus, ...j Fusarium Sp, Alternaria Sp, Cladesporium Sp, Gliocladium Sp. and Trichotecium Sp. were the
most frequently detected microorganisms respectively.
Conclusion: The presence of moulds suc as Aspergillus Sp, Penicillium Sp, Fusarium Sp, Alternaria Sp,
Cladesporium Sp, Gliocladium Sp, and Trichotecium Sp. in consumer wheat samples can lead to the
presence ofhannful mycotoxins and then could result in serious toxicity and illness in humans. As the fungal
contamination has a strong influence on the ultimate quality of wheat, wheat end products and food safety,
more attention to the quality and safety of wheat and wheat stored places are necessary.
