What happens depends on the type and amount of mold, but a small accidental bite often causes no harm. If symptoms do happen, they’re usually stomach upset like nausea, vomiting, diarrhea, or cramps, and some people can also have allergic reactions such as itching, rash, or a runny nose.

What to watch for

  • Mild symptoms: nausea, vomiting, diarrhea, stomach cramps.
  • Allergic symptoms: itching, rash, nasal congestion, sneezing, runny nose.
  • More serious concern: the moldy food may also carry bacteria or toxins, which can make you sicker than the mold itself.

What to do

  • Spit it out and rinse your mouth if you realize immediately.
  • Drink water and monitor for symptoms.
  • Throw the food away ; cutting off the moldy part is not always safe, especially for soft or moist foods because contamination can spread.

Get medical help if

  • You have shortness of breath.
  • You have persistent vomiting or diarrhea , especially if it lasts more than three days.
  • You see blood in your stool.
  • You feel very unwell, feverish, or dehydrated.
