The CDC says that dozens of new cases have been identified in the E.coli outbreak linked to California-grown romaine lettuce, CBS San Francisco reports.
The CDC reported that 67 people in 19 states, including California, have become infected with E. coli O157:H7, up from 40 cases reported late last week.
Thirty-nine people have been hospitalized, and six people developed hemolytic uremic syndrome, a type of kidney failure. No deaths have been reported.
The CDC said all types of romaine lettuce grown in the Salinas area, including whole heads of romaine, organic romaine, hearts of romaine, along with packages of precut lettuce and salad mixes containing romaine should be avoided.
Officials add that the outbreak is caused by the same strain of E. coli O157:H7 that caused outbreaks linked to romaine lettuce last year.
