Diners no longer need to worry about eating romaine lettuce. The FDA says the E. coli outbreak that sickened over 40 people stemmed from a contamination in California’s Central Coast. The growing season in that area is now over and will shift to California’s Imperial Valley, Arizona and Florida. Ahead of Thanksgiving, the FDA warned about the danger in eating any romaine lettuce. Romaine lettuce heading to store shelves now will be clearly labeled so people know it’s safe to eat.
