Natural occurrence of t-2 toxin in broiler,s feed commodities determined with ELISA

Abstract

Two hundred and twenty six broilers feed commodities were collected from different broiler flocks in Ninevah governorate(Iraq), through the period from January 2004 toDecember 2005. Enzyme linked immunosorbent assay method was used for T-2 toxin estimation. Results showed that, 81.5% of the total examined feed samples were positive to T-2 toxin contamination. Individually these percentages were as follows; 95% for wheat; 87% for corn; 85% for soybean; 74% for barley; and 70% for mixed feed. The range for T-2 contamination was between 8-1200 ppb. Most of the samples (58.4%) had low T-2 toxin natural contamination levels. Thirty two percent of positive samples had medium contamination level, while only 18.6% experienced high natural contamination levels with T-2 toxin.
