CANADA - Transport movements of swine from Ontario and the US remain a risk factor for spreading Porcine Epidemic Diarrhea, writes Bruce Cochrane.British Columbia, Alberta and Saskatchewan remain free of PED and all previously infected farms in Manitoba and Quebec have been declared free of infection but the virus continues to circulate through Ontario and the United States.Dr Julia Keenliside, a Veterinary Epidemiologist with Alberta Agriculture and Rural Development, told Alberta Pork's monthly telephone town hall yesterday transport movements from the US and Ontario continue to pose a risk.

　　布鲁斯·科克伦(Bruce Cochrane)写道，安大略省(Ontario)和美国的生猪运输活动依然是传播猪流行性腹泻病(PED)的一个风险因素。不列颠哥伦比亚省(British Columbia)、阿尔伯特省(Alberta)和萨斯喀彻温省(Saskatchewan)依然保持无猪流行性腹泻病的状态。曼尼托巴省(Manitoba)和魁北克省(Quebec)已经宣布所有先前被感染的农场不存在猪流行性腹泻病,但是病毒仍将通过安大略省与美国传播。阿尔伯特省农业及农村发展局的流行病学兽医茱莉亚(Julia Keenliside)博士在昨天的市政府电话会议上说：“安大略省和美国的生猪运输活动将持续造成风险。”
