CAMDEN — Maine health officials say one person has died following a salmonella outbreak at a retirement and assisted-living facility in Camden.

Dr. Stephen Sears, acting director of the Maine Center for Disease Control and Prevention, said seven cases of salmonella have been identified among residents at the Quarry Hill extended-care community.

A spokesman for Pen Bay Health Care, the parent organization of Quarry Hill, told the Bangor Daily News the outbreak was noticed Jan. 24 when several residents became ill with symptoms including diarrhea, cramps, headache, fever and vomiting. One person was hospitalized and another person, whose name was not released, died Feb. 2.

Sears said salmonella is usually food-borne, but epidemiologists have not been able to trace the cause of the outbreak.
