If you accidentally eat moldy food, you will probably be okay. Most likely, you wont experience any symptoms, but its important to be mindful of the fact that you ate it and make sure you dont have any symptoms for the rest of that day. However, in certain cases, the mold found on spoiled food could be dangerous, so if you suddenly develop symptoms such as prolonged nausea and vomiting, its recommended to see a doctor. Its worth noting that some molds can be very toxic to humans and can cause allergic reactions and respiratory problems. If youre relatively healthy and dont have a mold allergy, the gastric acid in your stomach, along with your immune response, should keep you from getting ill. However, if fungal invasion becomes systemic, the fungus can invade the digestive tract, upper respiratory tract, and brain, which can be more serious. To prevent mold, its best to throw away any food that has mold on it, and to store food in a clean and dry refrigerator.
