Jalapeño peppers linked to a multistate salmonella outbreak have been traced back to a grower in Sinaloa, Mexico, federal officials say. The company has recalled the peppers and is notifying its customers, which include some prominent Mexican food restaurant chains, officials said. Chipotle Mexican Grill said Tuesday that it had removed jalapeños from some of its restaurants. The agency may announce additional actions on its recalls webpage, health officials said. Mexico health officials said they opened an investigation and made a field visit Thursday to a packing plant in the northern state of Nuevo Leon.
