So apparently at my tiny Little urgent care/ER we have diagnosed several cases of this over the last week alone. We are in southern Indiana. If my facility is diagnosing this many, that means it is far more wide spread than 100 cases nationwide . Make sure you are washing your produce thoroughly. One decent way to do that is sprinkle some baking soda over it, use a 50-50 water/vinegar mix and let it bubble off all the gunk. Then thoroughly rinse with freshwater and dry. Wash your hands, too!
