However, the CDC maintained that "no common producer, supplier, distributor or brand of romaine lettuce has been identified" as being the source of the outbreak.
For this reason, the FDA has announced that red leaf lettuce, green leaf lettuce and Adam Bros. cauliflower. Farming Inc., in Santa Barbara County, were recalled. Reminders were later issued for sandwiches and other products from Northwest Cuisine Creations and Fresh & Local, as they were made from reclaimed lettuce or cauliflower.
