Corn is a staple in Mexican cuisine, used in countless dishes from tortillas and tamales to esquites and atole. However, the warm, humid conditions ideal for growing corn also create a perfect environment for mold growth, potentially leading to foodborne illnesses. Understanding the types of mold that can affect corn, the risks associated with consuming moldy corn, and effective prevention strategies are crucial for ensuring food safety.
What Kinds of Mold Can Grow on Corn?
Several types of mold can contaminate corn, both before and after harvest. Some common culprits include:
-
Aflatoxins: These are potent toxins produced by certain Aspergillus molds, particularly Aspergillus flavus and Aspergillus parasiticus. Aflatoxins can contaminate corn in the field and during storage if conditions are warm and humid. They are a significant concern as they are carcinogenic and can cause liver damage.
-
Fusarium molds: These molds can produce mycotoxins such as fumonisins, which are also associated with health risks including liver and kidney damage. Fusarium molds thrive in wet conditions and can infect corn during growth or storage.
-
Other molds: Numerous other mold species can grow on corn, some of which may produce mycotoxins or other harmful compounds. The specific types of mold present will depend on factors such as environmental conditions, corn variety, and storage practices.
What are the Risks of Eating Moldy Corn?
Consuming corn contaminated with mold can lead to several health problems, depending on the type and amount of mold present and the individual's sensitivity:
-
Mycotoxicosis: This is a general term for illness caused by consuming mycotoxins. Symptoms can range from mild gastrointestinal upset to severe liver or kidney damage, depending on the mycotoxin involved.
-
Allergic reactions: Some individuals may experience allergic reactions to mold spores, even if the mold itself doesn't produce toxins. These reactions can range from mild skin irritation to severe respiratory problems.
-
Infections: In rare cases, ingestion of moldy corn can lead to fungal infections, although this is less common than mycotoxicosis or allergic reactions.
How Can I Prevent Mold Growth on Corn?
Prevention is key to avoiding mold contamination in corn and corn-based products. Here are some essential strategies:
-
Proper Storage: Store corn in a cool, dry, and well-ventilated area. Keep cornmeal and other corn products in airtight containers to prevent moisture from getting in.
-
Careful Selection: When purchasing corn or corn products, check for signs of mold, such as discoloration, unusual spots, or a musty odor. Avoid purchasing any product that shows signs of spoilage.
-
Thorough Cooking: High heat can kill many types of mold, but it doesn't eliminate mycotoxins. Ensure corn and corn-based foods are cooked thoroughly to reduce the risk of mold exposure.
-
Hygiene: Maintain good hygiene practices throughout the food preparation process to prevent cross-contamination.
-
Early Detection: Regularly inspect stored corn and corn products for signs of mold and discard anything that looks suspect.
Can you get sick from eating a little bit of moldy corn?
Even a small amount of moldy corn can potentially contain mycotoxins, posing a health risk. It's best to err on the side of caution and avoid consuming any corn that shows signs of mold. The amount of mycotoxins present is unpredictable and can vary greatly.
How do you know if corn is moldy?
Moldy corn often exhibits visual clues such as discoloration (spots or patches of different colors), a musty or unpleasant odor, and a slimy or fuzzy texture. If you notice any of these signs, it's best to discard the corn.
Is it safe to eat corn tortillas if they have mold?
No, it is not safe to eat corn tortillas if they have mold. Mold can penetrate deep into the tortilla, and even if you remove the visible mold, mycotoxins might still be present.
What happens if you eat moldy corn?
The consequences of eating moldy corn depend on the type and amount of mold present. Symptoms can range from mild gastrointestinal issues to severe liver or kidney damage in cases of significant mycotoxin exposure. Seek medical attention if you experience any symptoms after consuming potentially moldy corn.

If you suspect you have consumed moldy corn and are experiencing symptoms, consult a doctor immediately. Remember, prevention is the best approach to avoid the risks associated with moldy corn in Mexican food.
