The folks at Dole have announced a recall of certain batches of its Italian Blend bag salads — including those it makes under the Kroger Fresh Selections Italian Style Blend name for the Kroger grocery store chain — over concern of possible Listeria contamination.

All the recalled salads have a Use-by Date of June 19, which means many people have either already eaten or discarded the product. Regardless, the Dole Italian Blend has a UPC code of 7143000819 and the Product Codes affected by the recall are 0049A157201A, 0049A157201B, 0049A157202A, 0049A157202B, 0686A157202A, 0686A157202B.

The Kroger Fresh Selections Italian Style Blend has a UPC code of 1111091045 and the affected Product Codes are A157201A and A157201B.

Both the Product Code and Use-by Date are in the upper right-hand corner of the package; the UPC code is on the back of the package, below the barcode.

These recalled salads — about 20,000 in total — were distributed in 12 U.S. states (Illinois, Indiana, Kentucky, Maine, Michigan, Mississippi, New Jersey, New York, Ohio, Pennsylvania, Tennessee and Wisconsin) and three Canadian provinces (New Brunswick, Ontario and Quebec).

The recall came about after a positive result for Listeria came up during random testing by the Ohio Dept. of Agriculture. However, Dole is labeling this recall as precautionary, noting that it knows of no illnesses.
