CDC comes close to an all-clear on romaine lettuce as E. coli outbreak nears historic level

It’s unlikely that anyone currently has edible romaine lettuce that is contaminated with the toxic strain of E. coli bacteria sickening people nationwide since March. That was the message Wednesday from the Centers for Disease Control and Prevention, and if not exactly a thundering signal of “all clear,” it was pretty close.

Romaine lettuce has a shelf life of about 21 days. The current outbreak has been traced to the Yuma, Ariz., growing region, the source of virtually all lettuce sold in this country during the winter months. The CDC said Wednesday that April 16 was the last day romaine lettuce was harvested in the Yuma area. The leafy-greens industry has shifted to California over the past two months.
