Eating moldy bread can be hazardous to your health, depending on the type of mold present and the amount consumed. Here are some things that can happen if you eat moldy bread:

• Allergic reactions: Some people can be allergic to mold, and eating moldy bread can trigger an allergic reaction. Symptoms can include shortness of breath, nausea, an elevated temperature, diarrhea, and even life-threatening anaphylaxis.

• Infections: Eating moldy bread can cause harmful infections, particularly if you have a weak immune system. Mold can produce harmful and invisible poisons called mycotoxins, which can spread through bread, particularly when mold growth is heavy.

• Nausea and vomiting: Eating moldy bread can cause nausea and vomiting, which are the most common symptoms of eating certain kinds of mold.

It is generally recommended that you do not eat moldy bread, and if you can visibly see mold on it, you should throw it out. Even if you cut off the moldy part, other harmful substances could still be left behind, and the mold roots can quickly spread through bread, though you cant see them. If you accidentally eat moldy bread, you should be mindful of the fact that you ate it and make sure you dont have any symptoms for the rest of that day. Most likely, youll be okay. However, if you suddenly develop symptoms such as shortness of breath, nausea, an elevated temperature, or diarrhea, you should immediately seek medical help.
