The Cumberland County Health Department said Friday it is investigating 87 people showing signs and symptoms of the illness. Seven cases have been confirmed.
All of the people affected ate at the Holiday Inn Bordeaux since May 1.
The health department is asking anyone who developed symptoms after eating at the Holiday Inn Bordeaux to call them at (910) 433-3638. For additional information, a salmonella hotline has been set up at (910) 433-3824.
To stop the further spread of the illness, the health department advises that hand washing is the best control measure.
The illness usually lasts 4 to 7 days, and most people recover without treatment. However, in some people, the diarrhea may be so severe that the patient needs to be hospitalized, or to be treated with antibiotics.
