7 sick from Salmonella at Costco deli in Washington

KOMO News reports a salmonella outbreak has been linked to food prepared in the service deli at the Costco Wholesale Warehouse in Issaquah, and now local health officials are closely monitoring the deli to make sure it is taking steps to prevent further problems.

An investigation by Public Health Seattle & King County found that seven people who got sick between August 2017 and July 2018 all tested positive for the same strain of salmonella, suggesting a common source for the infection.

As the investigation continued, officials discovered in August that all seven people who got sick had shopped at the Costco store in Issaquah. Of those, five bought ready-to-eat food from the service deli and one was an employee at the deli – although there was no evidence that the employee was the source of the outbreak.

It could not be confirmed whether or not the seventh person had purchased food at the Costco deli. One salmonella victim had to be hospitalized, but all seven have since recovered.

The Costco service deli prepares and sells a variety of ready-to-eat foods, but it could not be determined which of those was the source of the outbreak, King County health officials said.
