四川省屏山县提升屠宰企业非洲猪瘟检测能力的实践与思考

为提升四川省屏山县屠宰企业非洲猪瘟检测能力,采用问卷和现场调查、到场指导以及集中培训等方式,对辖区内5家屠宰企业非洲猪瘟检测实验室基本情况开展调查和软硬件提升指导,并对检测人员进行培训和开展现场比对试验。结果显示:2019年初建非洲猪瘟检测实验室以后,屏山县5家屠宰企业对实验室均进行了分区、添置设备等硬件改造,检测人员数量有所增加,专业人员和全职人员占比增高,年龄结构向年轻化转变,比对检测的平均符合率由48%提升到100%。这提示改造实验室硬件设施设备,优化检测人员队伍,加强检测人员培训,可显著提升屠宰企业非洲猪瘟检测能力。

甘肃省天水市生猪屠宰企业非洲猪瘟检测能力提升措施

着力加强和提升生猪屠宰企业非洲猪瘟检测实验室建设是有效防范非洲猪瘟传播的重要手段。为进一步提升屠宰企业非洲猪瘟自检能力,对甘肃省天水市生猪屠宰企业非洲猪瘟自检体系建设和运行情况进行了实地调研,并针对不足之处提出系列提升指导措施。调研发现:2019年以来,通过优化实验室配置、增加检测人员数量、加强检测人员培训和强化生物安全防护措施等,天水市屠宰企业非洲猪瘟检测能力明显提升。本文为我国其他地区生猪屠宰企业提升非洲猪瘟自检能力提供了参考。     

生猪屠宰环节“瘦肉精”快速检测存在的问题及对策

由于在生猪养殖业中违法使用瘦肉精的现象时有发生,不仅影响到生猪养殖业的健康发展,还会对百姓的身心健康造成伤害。为了遏制生猪养殖业违规添加"瘦肉精"现象,按照农业部要求,屠宰厂采用现场快速检测方法开展"瘦肉精"监督抽检。在规模大的屠宰厂存在着检疫人员层次不齐的情况,由于工作量大,时间紧,技术培训跟不上等情况;在区域发展不平衡的现实国情下,也存在不同程度的小规模定点屠宰厂,这些屠宰厂受到现实条件的影响。现就当前生猪屠宰厂"瘦肉精"快速检测中的存在问题作简要剖析,提出解决对策以供参考。     

平凉市生猪屠宰企业实验室非洲猪瘟检测能力比对结果分析

为了进一步评估生猪屠宰企业非洲猪瘟检测在生猪屠宰“两项制度”落实中发挥的积极作用,提升生猪屠宰企业非洲猪瘟自检能力,落实非洲猪瘟常态化防控措施。2020年平凉市10家生猪屠宰企业先后3次参加了省、市动物疫控机构组织的非洲猪瘟病毒核酸荧光PCR检测能力比对工作。结果显示:3次能力比对结果准确率分别为78%、84%和96.6%,并有逐次提高的趋势,有3家生猪屠宰企业3次非洲猪瘟病毒核酸检测比对结果均符合标准,占屠宰企业总数的30%,有7家生猪屠宰企业在3次比对中结果还不稳定,企业之间比对结果存在差异,对10家生猪屠宰企业3次非洲猪瘟病毒核酸检测能力比对结果影响因素综合分析结果表明,生猪屠宰企业实验室标准化程度越高、检测人员文化程度越高、屠宰企业管理越严格,非洲猪瘟检测能力比对结果越稳定,准确率越高。     

生猪屠宰环节的非洲猪瘟检测

首例非洲猪瘟自2018年8月3日在沈阳确诊以来,随后该病在全国范围内不断蔓延,给养猪行业带来了严重冲击。为进一步做好非洲猪瘟防控工作,降低生猪屠宰以及生猪产品流通环节病毒扩散风险,切实保障生猪产业健康发展。笔者作为调研组成员之一,通过实地随机抽查、查阅资料、听取汇报等方式,全面了解非洲猪瘟检测在生猪屠宰环节的基本情况,并对非洲猪瘟检测在生猪屠宰环节的现状、存在问题、意见建议方面进行了探析,以供借鉴参考。     

四川省宜宾市屠宰企业非洲猪瘟病毒核酸检测能力比对

屠宰企业的非洲猪瘟自检对切断病毒传播链条、打好非洲猪瘟攻坚战有着重要作用。为摸清四川省宜宾市屠宰企业的非洲猪瘟检测水平,对全市10个区县83家屠宰企业组织开展了非洲猪瘟检测能力比对工作。结果显示:屠宰企业检测人员偏少、岗位工作时间短、文化程度不高;不同区县、不同类别、不同组合的检测结果存在差异,有的差异较大。总的检测敏感性为49.72%,特异性为87.41%,准确率为66.56%。结果表明:屠宰企业的检测能力较为一般,监测风险预警效果不甚理想,有待加强。建议从保障人员队伍和加强操作培训两方面入手,提高屠宰企业非洲猪瘟检测能力。     

Heartworm in dogs in Canada in 1984

In late December 1984, 1853 institutional veterinarians and small and mixed animal clinics across Canada were sent a questionnaire in order to assess the status of Dirofilaria immitis in Canada in 1984 and 35% of them responded. Veterinarians reported that 97,794 dogs were blood-tested to check for microfilariae and 1417 dogs (1.45% of those tested) were found with heartworm. Another 34 dogs were amicrofilaremic, but were diagnosed as having heartworm disease, to give the total number diagnosed in 1984 as 1451 (1.48%). Heartworm was reported from all provinces except Prince Edward Island and Newfoundland but most (1310) of the cases were in Ontario. In Quebec, 126 cases were reported mostly from west of Montreal.

Heartworm was found most frequently in companion dogs over three years of age maintained mainly outdoors in rural areas. About 27% of the cases were observed with clinical signs of heartworm disease and 72% had a history of not having left Canada. Southwestern Ontario continued to be the primary focus of the infection.
