Is Corn Fungus Safe To Eat?

Corn fungus known as corn smut or huitlacoche, caused by the fungus Ustilago maydis, is safe to eat and is considered a delicacy in Mexican cuisine. It grows on corn ears, forming unusual swollen galls that look dark and tumor-like. Despite being a fungus that infects corn, huitlacoche has been consumed for centuries in Mexico with no widespread reports of harm.

However, some rare reports mention that people with severely weakened immune systems might experience infections or allergic reactions after consuming it, but these cases are unusual and not typical for healthy individuals. Nutritionally, huitlacoche is rich in protein, essential amino acids like lysine, dietary fiber, and B vitamins, making it a nutritious food.

In summary, for the general population, corn fungus (huitlacoche) is safe to eat and enjoyed in many traditional Mexican dishes such as quesadillas and tamales.
