The CDC, Arizona and Cochise County health departments investigated a total of 59 Salmonella Oranienburg cases diagnosed in the Sierra Vista area starting last September. The CDC traced 14 cases of illness to The Palms dining and banquet facility in Sierra Vista, but could not find a source of contamination for the other 45 cases. The Palms in Sierra Vista, a well-known banquet hall that regularly hosts large groups of people or private meetings, also happens to be where 14 people became infected with salmonella. The culprit was actually the iced tea machine. The Cochise County Health Department says that they found the Salmonella Oranienburg bacteria on the outer surface.
