Sterigmatocystin

Sterigmatocystin is a mycotoxin, a toxic compound produced by certain types of fungi, particularly Aspergillus versicolor and Aspergillus nidulans. It is closely related to aflatoxin, another mycotoxin produced by the same fungi.

Sterigmatocystin is commonly found in food products such as grains, nuts, and spices, as well as in animal feed. It is considered a potential human carcinogen and has been linked to liver damage, as well as other health effects.

The toxic effects of sterigmatocystin are thought to be similar to those of aflatoxin, including liver cancer and other liver damage. Sterigmatocystin can also cause mutations in DNA, which can lead to the development of cancer. However, the exact toxic effects of sterigmatocystin are not as well studied as those of aflatoxin.

To reduce the risk of exposure to sterigmatocystin, it is recommended to avoid consuming moldy or contaminated food products. Proper storage and handling of food products can also help to prevent fungal growth and mycotoxin production. Testing for sterigmatocystin levels in food products is also performed by regulatory agencies to ensure safety for human consumption.

In addition to the potential health risks to humans, sterigmatocystin can also have a negative impact on animal health and productivity. Therefore, it is important to monitor and control sterigmatocystin levels in animal feed as well.
