Zearalenone is a mycotoxin produced by certain molds, particularly those in the Fusarium genus. It commonly contaminates crops like corn and wheat, especially in warm and humid conditions. This toxin can affect livestock and may lead to reproductive issues in animals. In humans, zearalenone exposure is primarily a concern through the consumption of contaminated food products. It can mimic the hormone estrogen, potentially disrupting hormonal balance. Regulatory agencies monitor levels of zearalenone in food to ensure safety and minimize health risks associated with its consumption.
