Trichothecenes are a group of toxic compounds produced by certain molds, particularly those in the Fusarium genus. These mycotoxins can contaminate crops, especially grains like wheat and corn, posing risks to human and animal health when ingested. Exposure to trichothecenes can lead to various health issues, including nausea, vomiting, and immune system suppression. They are of particular concern in food safety, as they can affect the quality of agricultural products and lead to economic losses in the farming industry.
