(Sept. 8) Monterey Mushrooms Inc., Watsonville, Calif., has recalled about 10,000 cases of sliced white and Baby Bella mushrooms processed Aug. 25 to Sept. 4 in its Temple, Pa., facility because of a random positive test result for Listeria monocytogenes.

Joe Caldwell, vice president, said many of the packages already have been removed or have expired because of the products’ seven- to nine-day shelf life.

Third-party auditors visited the facility, but no contaminated product was found. A slicing machine may have been the culprit, Caldwell said.

The equipment has been redesigned and sanitization procedures updated, effective Sept. 5, to eliminate the risk, he said.

Monterey Mushrooms asked retailers in seven states — Ohio, New York, Pennsylvania, Maryland, Virginia, North Carolina, New Jersey — to remove the product on Sept. 6.

Caldwell said no complaints or illnesses have been reported.
