QUINCY, Mass. – Stop & Shop is voluntarily recalling tuna salad because it could be contaminated with Listeria.

The supermarket chain says the recall covers prepackaged 12 oz. containers of Stop & Shop Tuna Salad with a sell-by date of Aug. 19, as well as tuna salad sold at the service deli.

Customers can return the product to stores for a full refund.

The company says no illnesses have been reported. The bacteria Listeria monocytogenes can be fatal to the elderly, newborns and people with weakened immune systems. It can also cause miscarriages.

Home Made Food Brands of Newburyport, Mass., says the tuna salad was distributed to stores in Massachusetts, Rhode Island, Connecticut, Maine, New Hampshire and New Jersey.
