Due to possible Listeria risk, Dole Fresh Vegetables is voluntarily recalling 1,077 cases of bagged salads, most of which are likely not on shelves any longer.

The products being recalled are Kroger Fresh Selections Greener Supreme coded N158 211B 1613 KR04 with Use-by date of June 19 and UPC 11110 91039, Kroger Fresh Selections Leafy Romaine coded N158 111B KR11 with Use-by date of June 19 and UPC 11110 91046 and Wal Mart Marketside Leafy Romaine coded N158111B with Use-by date of June 19 and UPC code 81131 02781.

Dole Fresh Vegetables said it is coordinating closely with regulatory officials and that to date no illnesses have been reported in association with the recall.

The Product Code and Use-by date are in the upper right-hand corner of the package and the UPC code is on the back of the package, below the barcode. The salads were distributed in six U.S. states (Georgia, Kentucky, North Carolina, South Carolina, Tennessee and Virginia).

“This precautionary recall notification is being issued due to an isolated instance in which a sample of Marketside Leafy Romaine salad yielded a positive result for Listeria monocytogenes in a random sample test conducted by the State of North Carolina,” said Dole in a release.

The company said no other Wal Mart Marketside, or Kroger Fresh Selections salads are included in the recall.

Only the specific Product Codes, UPC codes and June 19, 2012 Use-by date identified above are included in the recall. Consumers who have any remaining product with these Product Codes should not consume it, but rather discard it.

Retailers and consumers with questions may call the Dole Food Company Consumer Response Center at (800) 356-3111, which is open 8:00 am to 3:00 pm (PDT) Monday – Friday.

Dole said it was unlikely the product is still on grocery shelves, but asked retailers to double check.

“Although the product is 3 days past its Use-by date and it is highly unlikely that any product is still available at retail, retailers should check their inventories and store shelves to confirm that none of the product is mistakenly present or available for purchase by consumers or in warehouse inventories,” said the company. “Dole Fresh Vegetables customer service representatives are already contacting retailers and are in the process of confirming that the recalled product is not in the stream of commerce.”

Listeria monocytogenes can cause serious foodborne illness and is especially a risk for those who are immune-compromised like the elderly or pregnant women.  Symptoms of infection may include fever, muscle aches, gastrointestinal symptoms such as nausea or diarrhea.
