CDC, public health and regulatory officials in several states, Canada and FDA are investigating a multistate outbreak of Shiga toxin-producing E. coli O157:H7 infections linked to romaine lettuce. CDC is advising that U.S. consumers not eat any romaine lettuce and they should throw it away. They are advising retailers and restaurants to not serve or sell any romaine lettuce, including salads and salad mixes containing romaine, until more is known about the outbreak. Restaurants, retailers, and consumers should clean and sanitize surfaces where romaine lettuce was stored.
