Ochratoxin A is a naturally occurring mycotoxin produced by certain molds, particularly Aspergillus and Penicillium species. It can contaminate various food products, including grains, coffee, and dried fruits, posing health risks to humans and animals. Exposure to ochratoxin A has been linked to kidney damage and may have carcinogenic effects. Regulatory agencies monitor its levels in food to ensure safety, as it can accumulate in the body over time. Proper storage and handling of susceptible foods can help reduce the risk of contamination.
