Lucky Charms making people sick? FDA looking into reports of cereal causing illness.

The Food and Drug Administration said it is looking into recent online reports of the popular cereal Lucky Charms causing gastrointestinal issues in some consumers.

On the website iwaspoisoned.com, where people can report any food-related illnesses and share the city and state where they received the food, over 1,300 people have said as of Monday they've felt sick since April 1 after eating the breakfast cereal. Most of the reported symptoms include nausea, vomiting and diarrhea, and cases have been reported throughout the United States.

"We recommend anyone who fell ill after eating Lucky Charms to report it and to keep leftover product for testing. We will communicate procedures for testing to everyone who reports their case," the website reads.

"The FDA is aware of reports and is looking into the matter," the FDA said in a statement to USA TODAY. "The FDA takes seriously any reports of possible adulteration of a food that may also cause illnesses or injury."

The FDA said it has received few complaints directly. The agency has its own food reporting protocols through its Center for Food Safety and Applied Nutrition system. The CFSAN Adverse Event Reporting System is a database that collects complaints made about any food, dietary supplement and cosmetic product.

Since 2004, the FDA said it has received 41 reports related to Lucky Charms, with only three since 2021. Of those three reports, only one is related to a complaint also listed on iwaspoisioned.com.

The FDA said it does not discuss details of a possible or ongoing investigation, but added depending on the seriousness of a problem, it would send investigators to visit a person who has made a complaint and investigate the cause of their sickness. If the problem isn't serious, each incident is tracked and may be used for a future inspection of a company and the plant in which the product is made. No product recall has been made for Lucky Charms as of Monday.

"The agency has received no calls at the FDA’s Food and Cosmetic Information Center related to Lucky Charms," it said.

General Mills, which makes the cereal, also said it has "not found any evidence that these complaints are attributed to our products" after an internal investigation.

"Food safety is our top priority. We take the consumer concerns reported via a third-party website very seriously," Andrea Williamson, General Mills spokesperson, told USA TODAY. "We encourage consumers to please share any concerns directly with General Mills to ensure they can be appropriately addressed."
