The San Francisco Department of Public Health released an update on Friday to the Burma Superstar E. coli outbreak that occurred around August 16.
Health officials now believe 12 people were sickened in connection to the outbreak, with 10 of them having dined at the restaurant. Of those diners, five were hospitalized, but have all since been discharged, according to Dr. Tomás J. Aragón, director of the city’s Population Health Division.
Two of the five hospitalized developed hemolytic uremic syndrome, a life-threatening kidney disease associated with severe E. coli infections.
Health officials have not determined the food source in the outbreak, but they say the investigation is ongoing. They are continuing to monitor for new cases, though none have appeared.
