A new PCR-based bioassay strategy for the detection of type A trichothecenes in food.

Type A trichothecenes (primarily T-2 and HT-2 toxins) are common fungal metabolites found in a wide range of grains and other field crops grown in temperate climatic zones. By acting as potent inhibitors of protein synthesis, T-2 and HT-2 exert adverse effects particularly against rapidly proliferating tissues, including the bone marrow, the immune system and epithelial cells. Based on toxicity studies in laboratory and farm animals, a temporary tolerable daily intake for the sum of T-2 and HT-2 has been issued in the European Union.
