A voluntary recall of past-shelf-date bagged salads distributed by Dole was initiated on June 22, 2012 due to concerns of possible contamination by listeria moncytogenes, a bacteria that can cause serious or even life threatening illness in people with weakened or compromised immune systems such as pregnant women, children and the elderly. The recall is limited to a specific group of select Kroger and Walmart labeled salads which are past their sell by date. Retailers are urged to check their inventories and concerned parties are encouraged to contact Dole customer service for more information regarding this recall, which has been issued in cooperation with a request made by the United States Food and Drug Administration after routine random product testing revealed the presence of listeria in a small sample. This recall includes more than 1,000 cases of bagged salads including Kroger Fresh Selections Leafy Romaine coded N158 111B KR11 with Use-by date of June 19 and UPC 11110 91046, Wal Mart Marketside Leafy Romaine coded N158111B with Use-by date of June19 and UPC code 81131 02781, and Kroger Fresh Selections Greener Supreme coded N158 211B 1613 KR04 with Use-by date of June 19 and UPC 11110 91039. Consumers can check the product code and use by date in the upper right hand corner of the salad packaging, and the UPC code is on the back of the bag immediately below the bar code. Symptoms of listeria infection can include: nausea or diarrhea, fever, and muscle aches.
