Illinois is one of 16 states that are part of a recall on romaine lettuce harvested from the Salinas, California growing region. The Centers for Disease Control, public health and regulatory officials, and the U.S. Food and Drug Administration are investigating an outbreak of E.coli infections linked to the lettuce. The recall includes all types of romaine harvested from Salinas, including whole heads, hearts of romaine, and packages of pre-cut lettuce and salad mixes that contain romaine. The mixes include baby romaine, spring mix, and Caesar salad with packaging marked Salinas. Officials suggest if no growing region is listed on the romaine product, it should be thrown away.
