鸡蛋和肉鸡中沙门氏菌的风险评估

The Salmonella risk assessment provides information that should be useful in determining the impact intervention strategies may have on reducing cases of salmonellosis from contaminated eggs and poultry. In the risk assessment of Salmonella in broiler chickens, for example, it was determined that there is a relationship between changing the prevalence of Salmonella on the broiler chickens and reducing the risk of illness per serving. In the risk assessment of S. Enteritidis in eggs, reducing the prevalence of S. Enteritidis in poultry flocks was directly proportional to the reduction in risk to human health. The model can also be used to estimate the change in risk of human illness from changing storage times or temperature of eggs. However, comparison of effects of intervention measures, i.e. sensitivity analysis, cannot be done because this risk assessment is not conducted for a specific region or country, or for global settings. Data was collected from different countries for differ ent input parameters. If those data were changed reflecting a specific national situation, the impact of a measure would also be changed. Therefore, caution would be needed in interpreting the results of this risk assessment in Codex activities.
