(UPDATED COVERAGE, 4 P.M., MAY 1) A Wisconsin spinach processor has recalled about 8,000 retail packs and 1,200 pounds of wholesale and foodservice product because of salmonella fears.

A routine test by the Wisconsin Department of Agriculture, Trade and Consumer Protection resulted in a positive sample of salmonella in a bag of Arizona-grown curly leafy spinach packed by Milwaukee-based Kleen-Pak Foods, according to the Food and Drug Administration and Jerry Kowaleski, Kleen-Pak’s vice president.

No illnesses have been reported, and government tests found no salmonella in spinach in Kleen-Pak coolers, Kowaleski said. As of April 30, additional tests on the company’s processing equipment were pending.

The spinach was shipped  to Kleen-Pak by Pinto Creek Co. LLC, Queen Creek, Ariz., Kowaleski said.

The contaminated pack was found in a Sysco warehouse, Kowaleski said. Sysco was notified April 27, and both the state ag department and Kleen-Pak announced the recall April 29, he said.

The recalled product is Kleen-Pak-branded 10-ounce and 1-pound packages and has a use-by date of April 29, April 30 or May 1. It was distributed in Wisconsin, Minnesota and the Chicago area.
