What is buttermilk mold?

Buttermilk mold refers to a type of mold, specifically Penicillium, that can develop in buttermilk or similar dairy products. It thrives in moist, nutrient-rich environments and can produce mycotoxins, which may pose health risks if ingested. Proper storage and handling of dairy products can help prevent the growth of this mold. If visible mold is found, it's best to discard the affected product.
