In the investigations on the mode of outbreak, general symptoms and causative bacteria concerning a food poisoning incident that broke out on August 14, 1958 in a factory in Hiroshima prefecture, the author has been able to clarify the following points.<br>1. Of 269 persons partaking the same meals, 88 persons were attacked by food poisoning, namely, 32.7 per cent of the total; and of them 38.6 per cent developed the symptoms making them unable to work. A higher percentage was in female, but relatively severer cases were among males. As for the age range in the age ranging 20-30 years and in those above 50 years the percentage was low, but the symptoms in those above 50 years were relatively severe.<br>2. The latent period appeared to be 12-24 hours in most of them.<br>3. As for the symptoms the patients showed an acute gastroenteritic picture such as diarrhea, abdominal pain, nausea and vomiting, accompanied by fever and headache.<br>4. The majority of them recovered on the second or on the third day afterwards.<br>5. The food in question was assumed to be the ones served on August 13th, the day before the outbreak of poisoning. From the findings of excreta culture in 5 patients Salmonella were detected, and by the antigen analysis it was determined as Salmonella dublin.
