In spring 2004, an outbreak of highly pathogenic avian influenza (HPAI), subtype H7N3, occurred in the Fraser Valley of British Columbia, Canada. The active outbreak lasted more than 90 days; 42 commercial poultry farms were identified as infected premises, and more than 17 million birds were culled. Through the depopulation of HPAI-positive farms and the strategic depopulation of adjacent test-negative farms, a total of 410 commercial poultry farms were emptied. The goals for the commercial poultry industry were to expedite restocking, reduce nonproductive downtime, negotiate equitable financial compensation, review and restructure emergency disease response plans, and identify and implement mitigation strategies. After the outbreak, multijurisdictional reviews identified the strengths and weaknesses of the outbreak control strategy. Lessons learned were incorporated into current emergency disease response protocols for both industry and government. The industry-led challenge to initial compensation values, especially for specialty poultry and breeder birds, resulted in a review of the federal Health of Animals Act. The British Columbia poultry industry, in collaboration with the British Columbia Ministry of Agriculture and Lands, developed an Enhanced Biosecurity Initiative that included the identification of mandatory on-farm biosecurity standards for commercial producers, an educational biosecurity self-assessment guide, and provisions for a producer self-quarantine to be enacted upon the first suspicion of disease.
2004年春季,加拿大不列颠哥伦比亚省弗雷泽河谷爆发了高致病性禽流感(HPAI)H7N3亚型疫情。此次疫情持续了90多天;42个商业家禽养殖场被确定为受感染场所,超过1700万只禽类被扑杀。通过对HPAI阳性养殖场进行扑杀以及对相邻检测呈阴性的养殖场进行战略性扑杀,共有410个商业家禽养殖场被清空。商业家禽业的目标是加快重新补栏、减少非生产性停机时间、协商公平的经济补偿、审查和重组应急疾病应对计划,以及确定和实施缓解策略。疫情爆发后,多部门审查确定了疫情控制策略的优势和劣势。吸取的经验教训被纳入了行业和政府当前的应急疾病应对方案。行业对初始补偿价值提出的质疑,尤其是对特种家禽和种禽的补偿,促使对联邦《动物健康法》进行了审查。不列颠哥伦比亚省家禽业与该省农业和土地部合作,制定了一项强化生物安全倡议,其中包括为商业生产者确定强制性的农场生物安全标准、一份生物安全教育自我评估指南,以及在首次怀疑疾病时实施生产者自我隔离的规定。
