The Lincoln County Public Health Division in Newport, OR, announced Wednesday that the restaurant in Otis, OR, where Serena Profitt, 4, and her friend, Brad Sutton, 5, shared a turkey sandwich over Labor Day weekend was not the source of E. coli infection that later killed the girl, hospitalized her friend, and may have sickened a third child. Samples from the Roadhouse 18 Bar & Grill sent to the Oregon State Public Health Laboratory for analysis tested negative for E. coli bacteria, division officials said.
