[Estimation of ingestion time for suspected food in food-poisoning outbreaks].
We previously constructed a database of 341 food-poisoning cases involving various causative agents. Using this database, we developed a new method for estimating the ingestion time of a food suspected of causing a food-poisoning outbreak. We confirmed that the method is superior to conventional methods. In this report, estimation equations specific for seven separate causative agents were obtained using the original database. We analyzed 301 cases in the database and 14 cases not included in the database using the seven estimation equations, the estimation equation in our previous report and the conventional methods. The values estimated with the improved method showed higher correspondence and accuracy than those estimated by using the conventional methods or the method in our previous report. These results confirmed that the improved method is superior to the conventional methods and our previous method.
