The Maine Centers for Disease Control is investigating six cases of E. coli infection, and is working to determine the source of a potential outbreak, according to a story posted on the Bangor Daily News website. Four of the six cases in Kennebec, Androscoggin, Lincoln and Franklin counties have been confirmed positive for Shiga toxin-producing E. coli O157:H7 by the Health and Environmental Testing Laboratory, state epidemiologist Dr. Kathleen F. Gensheimer confirmed Friday.

Two other cases are pending and one other suspected case is under investigation, according to the health advisory issued by the CDC. Those afflicted, including one who was hospitalized, had bloody diarrhea, one of the common symptoms.

Gensheimer said Friday that two of the three cases are unrelated, a fact revealed through genetic testing. No place, event or food has been identified as a link in the investigation, she said.

Elsewhere, an E. coli outbreak has been traced to a restaurant, according to WAND  The El Rancherito restaurant in Effingham, Illinois, has been identified as the source of an E. coli outbreak that has resulted in at least six confirmed cases of E. coli O157:H7 among customers who ate at the El Rancherito restaurant in Effingham between September 11th and September 13th.

An investigation into two E. coli-infected students from Galena Elementary School in Indiana is ongoing.  The News and Tribune reported that a second has been hospitalized with similar symptoms, school officials confirmed Friday afternoon.
