Expert Elicitation to Estimate the Relative Risk of Food Safety Criteria Included in the Establishment-Based Risk Assessment Model for Canadian Hatcheries.

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.

It's time to apply outbreak response best practices to avian influenza: A national call to action.

Cases of high pathogenicity avian influenza (HPAI) in Canada are upon us again and with reports of infection in US dairy cattle and a dairy farmer in the United States, concern has been raised. Although panic isn't helpful, this heightened level of concern is appropriate, given that reports of human infections with the H5N1 virus often indicate high mortality rates. These can range from 14 to 50%. The current devastating impact of the virus on the poultry industry, as well as its propensity to mutate are also reasons for concern. At the same time, HPAI provides an opportunity for the poultry and livestock industries to align and organize coherently for the management of all zoonotic diseases and other industry issues. To manage HPAI more effectively, it is essential to align all stakeholders under Outbreak Response Best Practices using a formal Quality Management System (QMS). The objective of this article is to describe this approach with examples drawn from management of the Walkerton waterborne disease crisis. We urge the veterinary profession to rise to the challenge of HPAI and use it as a context in which to align more coherently with national stakeholders for the prevention and management of all priority issues within the areas of Agri-food and Public Health.

Les cas de grippe aviaire hautement pathogène (HPAI) sont de nouveau aux portes du Canada et, avec les rapports d'infection chez des bovins laitiers américains et chez un producteur laitier aux États-Unis, des inquiétudes ont été soulevées. Même si la panique n'aide pas, ce niveau d'inquiétude accru est approprié, étant donné que les rapports d'infections humaines par le virus H5N1 indiquent souvent des taux de mortalité élevés. Ceux-ci peuvent aller de 14 à 50 %. L'impact dévastateur actuel du virus sur l'industrie avicole, ainsi que sa propension à muter sont également des motifs d'inquiétude. Dans un même temps, l'HPAI offre aux secteurs de la volaille et de l'élevage l'opportunité de s'associer et de s'organiser de manière cohérente pour la gestion de toutes les maladies zoonotiques et d'autres problèmes industriels. Pour gérer l'HPAI plus efficacement, il est essentiel d'aligner toutes les parties prenantes sur les meilleures pratiques de réponse aux épidémies en utilisant un système de gestion de la qualité (QMS) formel. L'objectif de cet article est de décrire cette approche avec des exemples tirés de la gestion de la crise des maladies d'origine hydrique à Walkerton. Nous exhortons la profession vétérinaire à relever le défi de l'HPAI et à l'utiliser comme un contexte dans lequel s'aligner de manière plus cohérente avec les parties prenantes nationales pour la prévention et la gestion de toutes les questions prioritaires dans les domaines de l'agroalimentaire et de la santé publique.(Traduit par Docteur Serge Messier).

Identification and selection of food safety-related risk factors to be included in the Canadian Food Inspection Agency's Establishment-based Risk Assessment model for Hatcheries.

Towards the continuous improvement of its inspection system, the Canadian Food Inspection Agency (CFIA) is developing an Establishment-based Risk Assessment model for Hatcheries to allocate inspection resources based on the food safety risk associated with the Canadian hatcheries falling under its jurisdiction. The objectives of the current study were to identify and select critical food safety-related risk factors that would be included in this model, with a main focus on Salmonella. A literature review was used to develop a comprehensive list of risk factors that could potentially contribute to the food safety risk attributed to Canadian hatcheries operating in all production streams (breeders, layers, broilers, turkeys, waterfowl and game birds). The development of this list used a selection process that was conducted according to the availability of data sources, the clarity of definition and the measurability of the selected risk factors. A panel of experts reviewed and adjusted the identified risk factors. A final list of 29 risk factors was generated; 20 originated from the scientific literature and nine from the expert panel. Risk factors were grouped in three clusters according to whether they pertained to the inherent risk (nine factors identified), risk mitigation (nine factors identified) or compliance of a hatchery with its preventive control plan and regulatory requirements (11 factors identified). Criteria for assessing each risk factor were defined based on common practices used in the Canadian hatchery industry. This comprehensive list of risk factors and criteria represents useful information to support the design and implementation of a Canadian risk assessment model for hatcheries, but could also be used by like-minded food safety authorities.
