Cereal Vomiting Mystery - Lucky Charms, Center Line Michigan

8535 East 10 Mile Road, Center Line, 48015 Michigan, United States

Hate this food as it is; but my daughter loves it.

Until she had to be rushed to the emergency room for puking 9-10 times in a day, with a spiked fever of 103.
Hospital did a covid test, flu test, and many more tests. All negative. Saw all over the news the next day after taking her to emergency, and realized she had a bowl that day too. (She normally has eggs and maybe a bowl of cereal once a month). Interesting coincidence? Or was she poisoned. | Symptoms: Vomiting, Fever
