In June 2024, the CDC, FDA, in collaboration with US Poison Centers and state and local partners, investigated a series of illnesses associated with eating Diamond Shruumz-brand Chocolate Bars, Cones, and Gummies. A total of 180 outbreak associated cases had been reported by 34 states. Seventy-three cases were hospitalized. Two deaths occurred. Dates of first onset of signs and symptoms ranged from January 6, 2024 to September 12, 2024.

People who became ill after eating these products reported a variety of severe symptoms including seizures, central nervous system depression (loss of consciousness, confusion, sleepiness) agitation, abnormal heart rates, hyper/hypotension, nausea, and vomiting.

As part of this investigation, FDA and state partners have collected multiple samples of Diamond Shruumz-brand products for testing and analysis. Test results for two individual chocolate bars collected from a retail store identified the presence of the following:

• Diamond Shruumz Dark Chocolate Bar
