Two large outbreaks of salmonellosis originating in Spokane, Wash, in 1962 and 1963 were traced to commercially baked meringue pies. The presumptive source was bulk egg whites produced locally. Approximately 15, 000 cans of frozen egg products were seized and examined bacteriologically. Of 1,131 core samples of egg whites, 235 (20.8%) were found contaminated with one or more of seven different salmonella serotypes. The heavy contamination of poultry feeds and bulking of large quantities of cracked and dirty eggs without pasteurization are believed to have been responsible for the outbreaks in Spokane as well as several other serious outbreaks documented since 1960.
