Mycotoxins are toxic compounds produced by certain molds, which can grow on various crops and food products. These substances can contaminate grains, nuts, and fruits, posing health risks to humans and animals when ingested. Common types of mycotoxins include aflatoxins, ochratoxin A, and fumonisins, each associated with different health issues. Exposure to mycotoxins can lead to a range of adverse effects, including acute poisoning and long-term health problems such as liver damage and immune system suppression. Regulatory agencies monitor and set limits for mycotoxin levels in food to ensure safety and protect public health.
