an investigation on t-2 toxin contamination in wheat crops from 11 cities, iran

objective: the major fusarium toxins found in cereals and cereal-based products that can be harmful to both human and animal health are some trichothecenes, such as deoxynivalenol (don). methods: a recent scoop project, since toxinogenic fungi are cosmopolitan, mycotoxins are environmental pollutants present in virtually all parts of the world and causing diseases (mycotoxicoses) . this cross-sectional study was carried out in spring - summer .t-toxin levels vary in different cities of iran and are higher than national standard  limits(20-21μg/kg per bw)and , therefore, according to the harvesting programs for  the wheat crop . thus the ardebil city with a amount of 46.3ppb and sari, mazandaran province center, with the least amount of t-toxin by 27.2ppb have been defined respectively. results: because of the non-specific clinical signs of fusarium mycotoxicoses, data about feed quality are an important part of the case history and an inevitable part of the preventive measures is regular foodstuffs monitoring with mycological and mycotoxicological examinations. the elimination of mycotoxins from feedstuff is an open problem because the scope for mycotoxin decontamination is very limited. in countries with adequate information about mycotoxin occurrence, regular tests to control foodstuffs and detect widespread and serious toxins are currently being performed and this leads to the exclusion of products with higher than allowable limits.
