Which fungal toxin is known to interfere with reproduction and fetal development?

Zearalenone is correct because it is a mycotoxin produced primarily by the fungus Fusarium, which commonly contaminates grains and other plant materials. This toxin mimics estrogen, a hormone crucial for reproductive functions, and has been shown to affect the reproductive systems of both animals and humans. In animals, particularly livestock, exposure to zearalenone can lead to reproductive disorders, such as failure of ovulation, changes in reproductive tissues, and developmental problems in fetuses.

This impact on fertility and fetal development makes zearalenone particularly significant in food safety and public health, especially in agricultural communities where contaminated feed can affect livestock and, subsequently, the food supply. Understanding the effects of zearalenone is crucial for preventing its impact on reproduction and ensuring the health of both animals and humans who ingest contaminated products.
