Listeria strains isolated from environmental samples collected at Oregon Potato Co. in Pasco, Wash. closely resemble the strain linked to a multistate Listeria outbreak, according to the U.S. Food and Drug Administration (FDA). The outbreak, linked to frozen vegetables, has triggered the recall of hundreds of products sold under dozens of brand names. Earlier this this week, the Centers for Disease Control and Prevention (CDC) identified CRF Frozen Foods of Pasco, Wash. as one likely source of this outbreak. CRF packages and markets frozen vegetables and fruits. Oregon Potato is a grower and processor of fruits and vegetables including potatoes, carrots, corn, asparagus, peppers, peas, apples, pineapples and onions. Both companies have plants in Pasco. More
