Twenty-five more people contacted health officials Friday to say they were sickened in a mid-February salmonella outbreak linked to a Bentonville sushi restaurant.

Lab results thus far haven’t shown salmonella in the samples from Sushi King, but many people who have reported becoming sick ate at the restaurant. As of Friday, 114 people had reported becoming ill with symptoms of salmonellosis. The department has confirmed 27 of the 114 cases through lab tests.

Sushi King owner John Wei said Friday his restaurant remains voluntarily closed. He wants an all-clear from the health department before reopening. The restaurant has about 200 customers a day.

He does not know why people became sick and hopes the health department will find a cause.
