As of May 23, 2017, 29 cases of a new O121 infection have been identified in six provinces (Alberta, British Columbia, Newfoundland and Labrador, Ontario, Quebec and Saskatchewan) linked with the consumption of uncooked flour. One additional case was identified in a U.S. resident who traveled to Canada during the exposure period. Patients' ages ranged from 2-79 years (median = 23.5 years) and 50% were female. Eight patients were hospitalized, and one developed hemolytic uremic syndrome. Because of the recent emergence of outbreaks linked to flour, public health professionals should consider flour as a possible source in outbreaks and communicate the risk associated with flour and raw batter/dough exposure in public health messaging.
截至2017年5月23日，在六个省份（艾伯塔省、不列颠哥伦比亚省、纽芬兰与拉布拉多省、安大略省、魁北克省和萨斯喀彻温省）已确认29例新的O121感染病例，这些病例与食用生面粉有关。另外，一名在暴露期前往加拿大的美国居民也被确诊感染。患者年龄在2至79岁之间（中位数为23.5岁），50%为女性。8名患者住院治疗，其中1人发展为溶血性尿毒症综合征。由于近期出现了与面粉有关的疫情，公共卫生专业人员应将面粉视为疫情爆发的可能源头，并在公共卫生信息中传达与面粉以及生面糊/生面团接触相关的风险。
