2. Why are they being recalled? According to the Cheerios website, an incident at the Lodi facility "allowed wheat flour to enter our gluten-free oat-based system. As a result, original and Honey Nut Cheerios produced on several dates may contain wheat and were wrongly labeled gluten-free." Those products "could cause severe reactions or illness in people with wheat allergies, celiac disease or gluten intolerance," the company said.

3. Has anyone gotten sick? Yes. General Mills said it has directly received two reports of illness and is aware of other complaints online, ABC News reports.

4. I am sensitive to gluten or wheat. What do I do next? Do not eat the cereal. You should contact General Mills at 1-800-775-8370 to get a full refund or replacement.

5. I am not sensitive to gluten or wheat. Is the cereal safe for me to eat? Yes, according to the Cheerios website. "These products would be safe for people without celiac or who are not gluten intolerant or sensitive to wheat or gluten – and that would include most consumers," the company said.
