Abstract
Verotoxigenic Escherichia coli (VTEC) are important foodborne pathogens in Canada. VTEC of the O157:H7 serogroup have been the focus of regulatory action and surveillance in both Canada and the USA, due to their role in a number of high profile outbreaks. However, there is increasing evidence that other VTEC serogroups cause a substantial proportion of human illness. This issue is of particular importance to the cattle industry due to the role of beef as a vehicle for VTEC transmission. In this review, the evidence for non-O157 VTEC as cause of human illness in Canada and the potential for Canadian beef and cattle to serve as a source of VTEC are presented. In addition, the available strategies for the control of VTEC in cattle and beef are discussed.
摘要
产志贺毒素大肠杆菌（VTEC）是加拿大重要的食源性病原体。O157:H7血清型的VTEC一直是加拿大和美国监管行动及监测的重点，因为它们在多起备受瞩目的疫情中发挥了作用。然而，越来越多的证据表明，其他VTEC血清型导致了相当一部分人类疾病。由于牛肉是VTEC传播的载体，这个问题对养牛业尤为重要。在这篇综述中，阐述了加拿大非O157 VTEC作为人类疾病病因的证据以及加拿大牛肉和牛作为VTEC来源的可能性。此外，还讨论了控制牛和牛肉中VTEC的可用策略。
