Recall: Ready-to-eat chicken salad may be tainted with Listeria WASHINGTON, Oct. 27 (UPI) -- Boston Salads and Provisions Company is recalling about 222,959 pounds of chicken salad products due to possible contamination with Listeria, officials say. The U.S. Department of Agriculture's Food Safety and Inspection Service said the ready-to-eat products were produced between Aug. 23, 2013, and Oct. 14, 2013, and were shipped to wholesalers for further distribution to retail locations in Massachusetts and New Hampshire. The products -- in packages ranging from 7 ounces to 30 pounds -- subject to recall include: Boston Salads Chicken Salad. Boston Salads Cranberry Walnut Chicken Salad. Boston Salads White Chicken Salad. Dietz & Watson Cranberry Walnut Chicken Salad. Dietz & Watson Tropical Cranberry Walnut. Dietz & Watson White Chicken Salad. Market Source Cranberry Walnut Chicken Salad. Northern Haserot Cranberry Walnut Chicken Salad. Price Chopper Cranberry Walnut Chicken Salad. Rachael's Gourmet Caesar Chicken Salad. Rachael's Gourmet Chicken Caesar Salad. Rachael's Gourmet Chicken Salad. Rachael's Gourmet Cranberry Walnut Chicken Salad. Rachael's Gourmet White Chicken Salad. Case labels or packaging may bear the sell by dates ranging from "9/13/2013" through "11/4/2013" as well as the establishment number "P-17999" inside the USDA mark of inspection. Although product included in this recall may be expired, FSIS is concerned that some product may be frozen in consumer or retail freezers. The problem was discovered when the New Hampshire Department of Public Health determined that two non-intact samples tested positive for Listeria. The Massachusetts Department of Public Health also tested intact samples of product, with two testing positive for Listeria. The firm's investigation identified a likely source of the contamination. Neither the government or the company have received reports of illnesses due to consumption of these products. Anyone concerned about an illness should contact a healthcare provider.
