Mycotoxins are toxic compounds produced by certain molds, which can grow on various crops and food products. These harmful substances can contaminate grains, nuts, and fruits, posing health risks to humans and animals when ingested. Common molds that produce mycotoxins include Aspergillus, Penicillium, and Fusarium. Exposure to mycotoxins can lead to a range of health issues, including acute poisoning and long-term effects like immune system suppression and cancer. Regulatory agencies, such as the Food and Drug Administration (FDA), monitor and set limits on mycotoxin levels in food to protect public health.
