Will drinking a little ice tea with mold make you sick?

Yes, it is possible that drinking iced tea with mold could make you sick. Mold can produce harmful mycotoxins that can cause a variety of health problems, including gastrointestinal issues such as nausea, vomiting, and diarrhea, as well as respiratory problems and allergic reactions. It's best to avoid consuming any food or drink that has visible mold on it. If you're unsure whether a food or drink is safe, it's always best to err on the side of caution and discard it.
