Napa Valley Register reports several people reported getting sick with Salmonella after eating at Morimoto Napa last month, according to Napa County Public Health.

There are at least six confirmed cases of salmonella-related food borne illnesses in customers who dined at the restaurant on Main Street between Oct. 10 and Oct. 12, said Dr. Karen Relucio, the county’s chief public health officer.

Relucio confirmed that the restaurant has been cooperative. During their investigation, she said, officials found that the restaurant was very clean and organized with strict operating procedures. Although the source of the salmonella outbreak is still under investigation, Relucio said that the department didn’t see any risk of ongoing transmission associated with eating at Morimoto Napa.

Salmonella, a type of bacteria that causes food poisoning, can be found in a variety of different food products, including chicken, beef, pork, eggs, tomatoes and spouts. Eating raw or undercooked food increases the risk of getting sick, Relucio said. The symptoms usually appear between 12 and 72 hours after infection and include diarrhea, fever, and abdominal cramps.

The illness lasts between four and seven days, Relucio said, and most people recover without treatment. Still, she said, if someone gets sick with food poisoning after eating out, they should report it to either Public Health or Environmental Health.
