Tainted lettuce worries

An E. coli outbreak linked to romaine lettuce originated from one growing area in Arizona, according to authorities. More than 50 illnesses in 16 states are linked to the tainted lettuce, according to the CDC's last official count. The CDC had previously warned consumers only about bagged chopped romaine lettuce but is now saying anyone who purchased any type of romaine lettuce?including whole heads or hearts of romaine?should throw it out if it came from the Yuma, Arizona, region.
