By KELLY MCCARTHY, ABC News (NEW YORK) -- Cubed, spiralized and pre-cut chunks of butternut squash are being recalled by two brands over listeria contamination concerns. Lancaster Foods LLC said the recalled products have "the potential to be contaminated with Listeria Monocytogenes, an organism which can cause serious and sometimes fatal infections in young children, frail or elderly people, and others with weakened immune systems." Twelve different butternut squash products were recalled. The products were sold in retail stores in North Carolina, Virginia, Washington, D.C., Maryland, Pennsylvania, New Jersey, New York, Connecticut, Rhode Island, New Hampshire, Vermont and Massachusetts.
