In May 2017, whole-genome sequencing (WGS) became the primary subtyping method for in Canada. As a result of the increased discriminatory power provided by WGS, 16 multi-jurisdictional outbreaks of associated with frozen raw breaded chicken products were identified between 2017 and 2019. The majority (15/16) were associated with , while the remaining outbreak was associated with Heidelberg. The 16 outbreaks included a total of 487 cases with ages ranging from 0 to 98 years (median: 24 years); 79 hospitalizations and two deaths were reported. Over the course of the outbreak investigations, 14 frozen raw breaded chicken products were recalled, and one was voluntarily withdrawn from the market. After previous changes to labelling and the issuance of public communication for these products proved ineffective at reducing illnesses, new industry requirements were issued in 2019, which required the implementation of measures at the manufacturing/processing level to reduce to below detectable amounts in frozen raw breaded chicken products. Since implementation, no further outbreaks of associated with frozen breaded chicken have been identified in Canada, a testament to the effectiveness of these risk mitigation measures.
2017年5月，全基因组测序（WGS）成为加拿大主要的亚型分类方法。由于WGS提供了更强的鉴别能力，2017年至2019年间共发现16起与冷冻裹面包屑鸡肉产品相关的多辖区弯曲杆菌疫情。大多数（15/16）与空肠弯曲杆菌有关，其余疫情与海德堡弯曲杆菌有关。这16起疫情共涉及487例病例，年龄从0岁至98岁不等（中位数：24岁）；报告了79例住院病例和2例死亡病例。在疫情调查过程中，召回了14种冷冻裹面包屑鸡肉产品，其中1种产品被自愿从市场上撤下。此前针对这些产品的标签更改和发布公共宣传在减少疾病方面被证明无效后，2019年发布了新的行业要求，要求在制造/加工层面实施措施，将冷冻裹面包屑鸡肉产品中的弯曲杆菌减少到可检测量以下。自实施以来，加拿大未再发现与冷冻裹面包屑鸡肉相关的弯曲杆菌疫情，证明了这些风险缓解措施的有效性。
