A Belgrade Fall Festival outbreak in Bozeman, Montana has allegedly sickened at least 200 people, according to the Gallatin City-County Health Department and news reports. The Festival was held at the Belgrade Senior Center. According to the Gallatin City-County Health Department Facebook page, beef brisket served at the festival on September 16, 2023 is suspected as the source of these illnesses. All but one of those sickened ate the brisket.
Officials do not know what pathogen caused this illness. Event coordinators are cooperating with the health department in its investigation of this outbreak. According to NBC Montana, the beef brisket is a tradition at that festival. The Belgrade Chamber of Commerce smokes the beef overnight before the day of the festival and serves the meat free of charge.
