摘要
If raw meat and poultry are the primary point of entry for Salmonella species into human populations, a correlation might be expected between the serotype distribution of Salmonella species isolated from animals at the time of slaughter and that of isolates found in humans. For 1990-1996, sufficient national data were available to permit such a comparison. A mathematical model was developed to predict serotype distributions of Salmonella isolates among humans on the basis of animal data. There was a significant mismatch between the serotype distributions among humans predicted by the model and those actually observed. This mismatch raises questions about the validity of the "standard" assumptions about Salmonella transmission on which the model was based-namely, that raw animal products are the primary source for human salmonellosis, that the risk of transmission to humans is equal for all food product categories, and that all Salmonella serotypes have an equal ability to cause human illness.
