The Gallatin City-County Health Department and the Department of Public Health and Human Services (DPHHS) are continuing their investigation into a foodborne illness outbreak linked to Dave’s Sushi in Bozeman. The investigation, involving local health departments and federal agencies, has yet to identify a specific pathogen as the source.

The outbreak is confined to individuals who dined at Dave’s Sushi between March 31 and April 17, 2023. Although the restaurant remains closed, officials state there is no ongoing risk to the public. DPHHS urges those who fell ill after eating at the establishment during this period to report their symptoms to local health departments for tracking purposes.

“DPHHS supports the Gallatin City-County Health Department with this investigation by coordinating with other local county health departments across the state who have reported illnesses associated with this outbreak. DPHHS is also working closely with federal partners assisting with this investigation, including the Centers for Disease Control and Prevention and Food and Drug Administration,” said DPHHS epidemiologist Rachel Hinnenkamp.

So far, at least 30 individuals have been identified in connection with this outbreak. Three suffered severe outcomes requiring hospitalization, while two deaths are under investigation following meals at the restaurant. The cause of death will remain pending until autopsy and toxicology results are available.

Investigations suggest that food containing morel mushrooms may be linked to these cases, though no pathogen or toxin has been confirmed. The morel mushrooms were cultivated in China, distributed through California, but not supplied to any other Montana establishments. No related illnesses have been reported in other states.

“We remain dedicated to working together with our state partners to investigate the potential pathogen or cause of this foodborne illness outbreak. Our collective efforts in this investigation will continue to be thorough and extensive. We are deeply saddened and extend our sincerest condolences to all the families and friends of the two deceased, as well as all those affected by this outbreak,” stated Lori Christenson from Gallatin City-County Health Department.

Public health officials emphasize that anyone can contract a foodborne illness from contaminated food. According to CDC estimates, 48 million Americans fall ill due to such diseases annually, leading to approximately 128,000 hospitalizations and 3,000 deaths. Vulnerable groups include seniors over 65 years old, children under five years old, pregnant women, and those with weakened immune systems.
