One person died and another was hospitalized in the last two weeks after a salmonella outbreak swept through Quarry Hill, a retirement and assisted living facility in Camden, Maine.

The Bangor Daily News cited Dr. Stephen Sears, acting director of the Maine Center for Disease Control and Prevention, as saying that seven positive cases of salmonella among the residents have been identified so far.

Quarry Hill offers independent living, assisted living, short- and long-term nursing care and rehabilitation and specialized memory-loss care to just over 150 people. Staff at the facility first became aware of the outbreak on Jan. 24, when several residents became ill with symptoms that included diarrhea, cramps, headache, fever and vomiting.

The Maine CDC sent two epidemiologists to the health care facility to try to find other sick residents and to identify a possible source. The experts also worked with facility staff to increase their education about salmonellosis, the infection caused by the salmonella bacteria.

Sears said efforts to track the cause of the outbreak have so far been fruitless. The strain of salmonella in the Camden outbreak has been identified as javiana.

He said that the Maine CDC has not seen other salmonella outbreaks from that strain in the state recently and that the problem appears to be “slowing down” at Quarry Hill, with no new cases reported in days.
