Abstract

Introduction. Surveillance of natural occurrence of T-2 toxin in cereals intended for human consumption.Materials and Methods. Cereal samples obtained from nine cooking centers of Tehran. The samples were powdered and extracted by methanol-water solution (70:30) and the level of their T-2 toxin assayed using a competitive monoclonal antibody based ELISA.Results. All cereal samples contained T-2 toxin ranging from 7.9 to 65.4 (mean: 17.9±2.1) µg/kg. Wheat samples with mean of 42.4 µg/kg were the most contaminated cereals flowed by barley and rice with 18.3 and 12.5 µg/kg respectively. Conclusion. Although, a minority of cereal samples (13.9 %) was contaminated with levels higher than nation standard of Iran for T-2 toxin, extended contamination with the toxin reveals existence of favorable condition for natural occurrence of mycotoxins in agricultural products, and mentions the risk of chronic effects of the toxin exposure and necessity of foodstuffs mycotoxins assay.
