During April 2022, there has been an increase in complaints of gastrointestinal illness (GI) attributed to eating Lucky Charms cereal reported primarily to a crowdsourcing website. Some complaints of illness have also been reported to the U.S. Food and Drug Administration (FDA), state, and local health departments. There are very little data on the clinical presentation of these complaints, e.g., symptom profiles, incubation periods, and illness durations, as well as a lack of laboratory testing of clinical specimens. The scarcity of data and lack of a consistent clinical presentation are making it difficult to ascertain if any of these illnesses are linked to the suspected cereal.
The Centers for Disease Control and Prevention (CDC) is coordinating with state and federal partners to characterize the clinical presentations and epidemiology of recent illness reports. CDC is also collaborating with state and federal partners to evaluate data collected from ill people to determine if an outbreak of GI illnesses is occurring and its potential link to Lucky Charms cereal.
