King County Public Health is investigating an outbreak of salmonellosis associated with food prepared in the service deli at the Costco Wholesale Warehouse in Issaquah.

The service deli prepares and sells ready-to-eat foods, including rotisserie chicken, pork ribs, sandwiches, wraps, macaroni and cheese, poke, cilantro lime shrimp, and shrimp cocktail.

Currently, the source of the illnesses has not been identified. Everyone who reported illness has recovered.

There have been seven cases resulting in one hospitalization. Illness onsets occurred sporadically during July 13 to Aug. 28, and a common epidemiological link among all cases was not established until August 2018.
