Update 2.13.19 - The Centers for Disease Control (CDC) has officially declared the U.S. outbreak to be over; the FDA continues to recommend to suppliers and distributors that romaine lettuce be labeled with a harvest location and a harvest date, or labeled as being hydroponically or greenhouse-grown.
December 17, 2018 - The FDA, along with CDC, state and local agencies, is investigating a multi-state outbreak of E. coli O157:H7 illnesses linked to romaine lettuce grown in California. Restaurants and retailers should not serve or sell romaine from Monterey, San Benito, and Santa Barbara counties in California. Romaine from outside those regions need not be avoided.
On December 13, 2018, Adam Bros. Farming, Inc., in Santa Barbara County, recalled products that may have come into contact with water from the water reservoir where the outbreak strain was found. The firm recalled red leaf lettuce, green leaf lettuce and cauliflower harvested on November 27 through 30, 2018. According to the firm, cauliflower was distributed to wholesalers in the U.S.
The Adam Bros. recall has prompted a sub-recall by Spokane Produce Inc. of Spokane, WA. The firm recalled sandwiches and other products under the Northwest Cuisine Creations and Fresh & Local Sandwiches & Green Leaf Filets.
