A cheese sold at Costco outlets in five states – none in Washington – has been preliminarily linked to E. coli, according to a report by Associated Press.

Federal officials and Costco said the outbreak has sickened 25 people. The cheese was sold and offered for in-store tasting between Oct. 5 and Nov. 1 at Costco stores in Arizona, Colorado, New Mexico, Nevada and in the San Diego area of California.

The cheese is the Bravo Farms Dutch Style Raw Milk Gouda Cheese .

Issaquah-based Costco is using its purchase records to notify customers who purchased the cheese and is working with federal health officials. No deaths have been reported.

Costco voluntarily removed the cheese from its shelves.

The cheese is manufactured by Bravo Farms of Traver, Calif., south of Fresno. The FDA said it and California state officials have begun an investigation at Bravo Farms. The first results of Costco’s own testing are expected today.
