Recognizing T-2 toxin
T-2 toxin is a kind of mycotoxin produced by many kinds of Fusarium, is the most toxic one among the toxins of monotrichous mycotoxins, which is widely existed in nature, mainly contaminating grain crops and their products such as wheat, barley, corn, etc., and posing a greater danger to human health and animal husbandry.
In 1974, the Food and Agriculture Organization of the United Nations (FAO) and the World Health Organization (WHO) listed T-2 toxin as one of the most dangerous natural pollutants, which is teratogenic and weakly carcinogenic, and mainly damages the hematopoietic organs (inhibiting regenerative and hematopoietic functions of the bone marrow and the spleen), the immune organs (lowering immune functions), the digestive system (causing hemorrhagic and necrotic deaths in the gastrointestinal tract), the nervous system, and the reproductive system of the animal organism.
Hazards to livestock
Clinical signs of T-2 toxin poisoning in pigs are characterized by dyspepsia, loss of appetite, slow growth, lesions in the mouth and skin, vomiting, and immunosuppression.
Hazards to poultry
Poultry T-2 toxin intoxication shows decreased egg production, laying of thin-shelled eggs, poor feather production, oral ulcers, decreased or even eliminated appetite, movement disorders, and reduced immunity.
Moreover, birds poisoned with T-2 toxin are more susceptible to Salmonella and Newcastle disease virus.
The new feed hygiene standard stipulates that the limit of T-2 toxin for plant-based feed ingredients and pig and poultry compound feed is 0.5mg/kg.
The new national standard GB 5009.118-2016 National Standard for Food Safety Determination of T-2 toxin in food stipulates three methods for T-2 toxin detection: the first method of immunoaffinity chromatography purification liquid chromatography, the second method of indirect ELISA, and the third method of direct ELISA.
T-2 toxin immunoaffinity column, using the principle of antigen-antibody specific reaction, high column capacity, effectively improve the purification efficiency; good stability, recovery ≥ 90%; good repeatability (CV%): <5%; suitable for a variety of complex samples detection, including cereals, feed and other samples.
T-2 Toxin ELISA Kit is a rapid qualitative and quantitative test for the determination of T-2 Toxin in cereals and feeds, and is suitable for rapid quantitative analysis of large quantities of samples.
