SALINAS, Calif. (AP) - A Northern California produce supplier is voluntarily recalling romaine lettuce that was shipped to Texas and 18 other states, as well as Puerto Rico and Canada, over fears of possible E. coli contamination. 
Salinas-based Tanimura & Antle said Sunday the recall is limited to a single lot of its Field Fresh Wrapped Single Head Romaine that was available at retail stores starting Aug. 2nd.
The recall is being conducted in consultation with FDA, and is based on the testing of a single random sample by the Canadian Food Inspection Agency.
The lettuce is packed in a plastic bag with the UPC number 0-27918-20314-9, and it may have a "best by" date of Aug. 19.
The company says some 2,095 cases are potentially affected.
The affected product was shipped in cases packed in either 12 or 18 heads per case. Retailers and distributors can identify the affected products through the traceability code label: 5417802151.
There have been no reported illnesses associated with consumption of this product
