Officials with the Westlake Village, Calif.-based Dole warned retailers and consumers that 2,800 cases of Dole-branded Italian blend salads could be contaminated with Listeria monocytogenes.

Dole officials said they initiated the recall after “an isolated instance” in which one package of the salads yielded a positive result for Listeria during random testing by the Ohio Department of Agriculture, according to the release.

Dole distributed the salads to retailers in Wisconsin, Ohio, Michigan, Illinois, Indiana, Kentucky, Tennessee, Mississippi, Pennsylvania, New Jersey, New York, Maine, and the Canadian provinces of New Brunswick, Ontario and Quebec.

The salads have June 19 use-by dates, 7143000819 UPC codes and these product codes: 0049A157201A, 0049A157201B, 0049A157202A, 0049A157202B, 0686A157202A and 0686A157202B. The recall includes 442 cases of Kroger Fresh Selections Italian Style Blend salad with June 19 use-by dates, UPC code 1111091045 and product codes A157201A and A157201B.

Dole reports no consumers have reported illnesses and says its customer service representatives are contacting retailers to verify the recalled product has been pulled from sale, according to the release.
