Last month it was Colorado's cantaloupe and this month it's California's lettuce. True Leaf Farms originally estimated that 90 cartons of their romaine lettuce was contaminated with listeria. Turns out that number is closer to 2,500. Roxann Bramlage, an auditor with the California Department of Food and Agriculture announced that 19 states and Canada are affected by the recall.
The states affected include Alaska, Alabama, Arizona, California, Colorado, Connecticut, Florida, Illinois, Kentucky, Maryland, Minnesota, Missouri, Nevada, New York, Ohio, Oregon, Pennsylvania, Tennessee and Vermont.
The lettuce began being tested for the bacteria in June and is expected to continue through 2012. Three potential outbreaks of listeriosis have been revealed since it's testing.
The recall mostly involves bagged romaine lettuce sold to restaurants, cafeterias, and other institutions.
