Owners of a Rock Springs restaurant have voluntarily closed due to a possible link to a salmonella outbreak. Seven or eight cases have been reported in Sweetwater County, and the county Health Department is investigating, the agency’s Jodye Wilmes said.

Officials said the cases might be linked to Sand’s Cafe on 9th Street.

The restaurant’s owners closed voluntarily and are contacting suppliers to help with the investigation. ”The owners of Sand’s are taking a very proactive view,” said George Lemich, attorney for the restaurant.

The cafe has begun extensive sanitizing of cooking and eating utensils, food preparation surfaces and other equipment, according to Wilmes and Lemich.
