Between March 28 and April 17, 2023, over 50 people experienced gastrointestinal symptoms after dining at Dave’s Sushi in Bozeman, Montana. Two individuals died, and three were hospitalized as a result of the outbreak. The Gallatin City-County Health Department (GCCHD) and the Montana Department of Public Health and Human Services (DPHHS), alongside the Centers for Disease Control and Prevention (CDC) and the U.S. Food and Drug Administration (FDA), have completed their investigation into this incident.

The investigation identified morel mushrooms consumed at the restaurant as strongly associated with the illnesses. DNA sequencing revealed that the species involved was Morchella sextelata, a type of true morel. GCCHD has been conducting regular inspections at Dave's Sushi to ensure it continues to operate safely. The restaurant remains cooperative with health officials.

Public health departments have released a summary report detailing their findings, which is available online for public access.

"Anyone eating, selling, or serving morel mushrooms should use caution when doing so," warned health officials. They advised that proper preparation techniques, including cooking, can reduce toxicity risks associated with consuming these mushrooms.

Health authorities highlighted that some poisonous wild mushrooms resemble morels closely. They recommend confirming each mushroom's identity with an expert before consumption to avoid confusion with toxic varieties.

To minimize risk, morel mushrooms should be stored at temperatures below 40°F in breathable packaging like paper bags and cooked thoroughly before eating.

Individuals who feel unwell after consuming morels are urged to seek medical attention promptly or contact the Poison Control Hotline at 1-800-222-1222.
