In 1985 82 samples of feed and food grain were analyzed for trichothecenes deoxynivalenol (DON), nivalenol (NV), diacetoxyscirpenol (DAS), T-2 toxin, HT-2 toxin and fusarenon-X (F-X). Trichothecenes were found in 77 of these samples. The highest amounts were DON 6300 ug/kg and DAS 1680 ug/kg.In 1986, in a corresponding study of 113 samples, trichothecenes were found in 110 samples. A new trichothecene in Finland, 3-acetyldeoxynivalenol (3-AcDON), was identified in 35 of these samples in concentration of 2-211 ug/kg.Analyzing methods were gas chromatography and GC-mass spectrometry. It is characteristic of the feed samples suspected of causing outbreaks in animals in Finland that several trichothecenes are often found in the same sample. As an example of this is a poultry feed with following results: DON 33 ug/kg, 3-AcDON 21 ug/kg, DAS 45 ug/kg, T-2 toxin 40 ug/kg, HT-2 toxin 12 ug/kg.

Heavy metals and mycotoxins are important contaminants in food pollution. Sensitive, reliable, and rapid detection of heavy metals and mycotoxins is crucial for human health. In this work, imidazole-functionalized aggregation-induced emission (AIE) molecule tetra-(4-pyridylphenyl) ethylene (TPPE) was used as a precise and specific probe for Ag detection, with a limit of detection (LOD) of 0.

T-2 toxin contamination in food and feed is a growing global concern, with its toxic effects on developing cartilage remaining poorly understood. In this study, we constructed an animal model using 4-week-old male Sprague-Dawley rats, which were administered T-2 toxin (200 ng/g body weight per day) by gavage for one month. Histological analysis showed a significant reduction in hypertrophic chondrocytes and increased caspase-3 expression and TUNEL staining in the deep cartilage zone of T-2 toxin-treated rats.

Co-occurrence of multiple mycotoxins is a growing global food safety concern due to their harmful effects on humans and animals. This study developed an eco-friendly sample preparation method and an innovative multiplex microarray-based lateral flow immunoassay, using a novel portable reader for on-site simultaneous determination of five regulated mycotoxins-aflatoxin B, T-2 toxin, zearalenone, deoxynivalenol, and fumonisin B in rice. The eco-friendly and ultrafast extraction procedure utilizes a bio-based solvent.

Mycotoxins are toxins produced by various types of fungi, including , which can produce different types of mycotoxins, such as Deoxynivalenol (DON), Zearalenone, T-2 toxin, and Fumonisins (FUM). Mycotoxins have the potential to reduce the quality of crops and pose health risks to both humans and animals. This can result in reduced animal production and substantial economic consequences on a global scale.
