The number of salmonella cases among children sickened after attending an etiquette class rose to 25 today.

Health officials don't expect to ever pinpoint the members-only club as the source of the outbreak. Investigators did target a food-handling practice at the club that "could potentially" have contributed to the infection of the fifth-graders who attended a September ninth banquet.

County health Director Colleen Bridger says the chicken wasn't cooked thoroughly.

Graham Bell, owner of The City Club of Gastonia, says the club now will either grill or bake chicken, but not do both for a meal as it did for the banquet.
