ROMAINES OF THE DAY

All of the E. colitainted lettuce from Arizona has almost certainly cycled off grocery store shelves by now, making the leafy vegetable safe to eat again, the Centers for Disease Control and Prevention said.

Romaine from Yuma, Ariz. — in all of its chopped, bagged, fresh and whole-hearted varieties — had been at the center of an outbreak that began in April affecting 172 people in 32 states, one of whom died. The threat was neutralized when romaine growing shifted to California over the past two months.
