In the past week and a half, seven confirmed salmonella cases have been reported in the Sierra Vista area.

Of the seven cases, two have been serotyped as Oranienburg, the same kind of salmonella that had been reported in another outbreak during the fall months. The other five cases have been serotyped as Enteridis, according to Karla Jensen, spokeswoman for the county health department.

Health officials have not been able to identify the source of the outbreak.
