CHICAGO (AP) — Chipotle Mexican Grill said Tuesday that it had removed jalapeños from some of its restaurants after determining the peppers could potentially be tied to a salmonella outbreak public health officials are investigating. The Minnesota Department of Health on Tuesday confirmed that it was investigating a salmonella outbreak tied to several Mexican-style, quick-service restaurants — with jalapeños as the suspected source. The Minnesota Department of Health noted that other states are contributing to the investigation, without elaborating further. On the federal level, the Food and Drug Administration is conducting the traceback probe, covering but not limited to jalapeños. Infections can be more severe in young children, older adults and people with weakened immune systems, who may require hospitalization.
