The Canadian Food Inspection Agency is developing an Establishment-based Risk Assessment model for Hatcheries to allocate inspection resources according to the food safety risk associated with each hatchery falling under its jurisdiction. In a previous study, 29 factors contributing to the food safety risk of hatcheries were identified and grouped into three clusters (inherent risk, risk mitigation, and compliance) and assessment criteria were defined. The objective of the current study was to estimate the relative risk (RR) of these criteria. Two rounds of expert elicitations were conducted to allow 13 Canadian experts to estimate the RR of each criterion (n = 96) based on its potential impact on human health, with a specific focus on Salmonella spp. This process also aimed to estimate the maximum increase or decrease in the overall food safety risk of a hatchery when considering multiple criteria belonging to a specific cluster and to assess the risk attribution of Salmonella spp. at the hatchery and bird-type levels. Results showed that the respondent profile had no influence on the importance given to a majority of criteria. Uniformity of answers among experts improved from the first to the second round. Overall, 62.5%, 32.3%, and 5.2% of the criteria were attributed to an RR that was less than 2, between 2 and 3, and greater than 3, respectively. Mixing eggs from different supply flocks when placed into the same hatching unit, hatching multiple species, and importing eggs with unknown quality status were identified as having the highest contribution to a hatchery's inherent risk. Requiring information on the foodborne pathogen status of supplying flocks and the occurrence of regulatory enforcement actions were the most impactful risk mitigation and compliance factors, respectively. The median RR value assigned to each criterion and cluster will be used to build this new model.

评估加拿大孵化场基于企业的风险评估模型中包含的食品安全标准的相对风险的专家征集。

加拿大食品检验局正在为孵化场开发基于企业的风险评估模型，以根据与其管辖范围内的每个孵化场相关的食品安全风险分配检验资源。在之前的一项研究中，确定了影响孵化场食品安全风险的 29 个因素，并将其分为三类（固有风险、风险缓解和合规性）并定义了评估标准。当前研究的目的是估计这些标准的相对风险 (RR)。进行了两轮专家征集，让 13 名加拿大专家根据每个标准 对人类健康的潜在影响（n = 96）估计其 RR，特别关注沙门氏菌属 该过程还旨在在考虑属于特定集群的多个标准时估计孵化场整体​​食品安全风险的最大增加或减少，并评估沙门氏菌的风险归属属 在孵化场和鸟类级别。结果表明，受访者概况对大多数标准的重要性没有影响。从第一轮到第二轮，专家答案的统一性有所提高。总体而言，62.5%、32.3% 和 5.2% 的标准分别归因于 RR 小于 2、介于 2 和 3 之间以及大于 3。将来自不同供应鸡群的鸡蛋混合放入同一孵化单元、孵化多个物种以及进口质量状态未知的鸡蛋被确定为对孵化场固有风险的贡献最大。需要有关供应鸡群食源性病原体状态的信息和监管执法行动的发生分别是最有影响力的风险缓解和合规因素。
