A Statistical Study of the Number of Patients Caused by Bacterial Food Poisoning in Several Pathogens and Places

The ratio of patient number of the bacterial food poisoning in several pathogens and places are investigated by the statistical method. Present data is consisted of a number of patients, pathogens and places obtained from the Annual Report of Food-born Disease in Japan during the period of 1984-1988. The pathogen examined in this study are Vibrio parahaemolyticus, Salmonella and Staphylococcus.Present results shows that 1; the present data expressed nearly in logarithms, and the number of patients in corresponded to (log (x+1) ) . 2; There is strongly correlated between the places and a number of patients caused by those bacterial poisoning diseases. 3; The ratio of the patient number and occurrence interval might be estimated by determining of the mean values and occurrences limits (mean ±2×S.D.) of bacterial food poisoning in pathogen, place and place-pathogen cross-link.The number of patients is mostly affected with Vibrio parahaemolyticus in the pathogen and also with school-nursey and caterer·box lunch service in the place. They are also affected with Salmonella in the pathogen, and with school·nursery in the place, and also with Staphylococcus in place-pathogen cross-link.
