What happens if you eat jelly that's gone bad?

Eating jelly that has gone bad can lead to foodborne illness due to the growth of harmful bacteria, mold, or yeast. Symptoms may include nausea, vomiting, diarrhea, and stomach cramps. If the jelly has an off smell, unusual color, or visible mold, it's best to discard it to avoid any health risks. Always check expiration dates and storage conditions to ensure food safety.
