The number of cases of salmonella has risen to 18 including four people who are in the hospital.
All of them ate at the Holiday Inn Bordeaux since May 1.
The Holiday Inn Bordeaux has two restaurants, the All American Sports Bar and Grill and the Café Bordeaux. There is also a banquet kitchen.
Mae Freeman says she has never felt so sick in her life. Last Wednesday, she ate at the Holiday Inn hotel, and a day later she felt terrible.
"At first, I thought I was coming down with something because I had chills, and then I was running a high temperature, and then all of a sudden I had this severe case of diarrhea and severe abdominal cramps," said Freeman.
Freeman says her doctor told her she had salmonella poisoning.
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.
"It's key for folks to let us know they have eaten there so we can get in touch with people they may have had contact with because the number one transmission is person to person," said Wilson. "We have met with the kitchen staff, and they have agreed to replace some equipment that may not have been sanitized properly."
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.
