The US Centers for Disease Control and Prevention has expanded its warning about an E. coli outbreak connected to romaine lettuce to cover all forms of romaine, including whole heads and hearts of romaine grown in the Yuma, Arizona, growing area. A previous warning was limited to chopped forms of romaine, including salads and salad mixes.
The CDC based the new warning on eight new cases of acute gastroenteritis at a correctional facility in Nome, Alaska, that appear to be connected to the current outbreak affecting 53 people in 16 states. Thirty-one of those have been hospitalized, the CDC said, and although no one has died, five people have developed a type of kidney failure called hemolytic uremic syndrome.
