吓skr人!我国大规模非洲猪瘟疫情来了!能不能愉快地吃猪肉了?

2019-01-04 高雅 医师报

在辞旧迎新之际,非洲猪瘟凭借着其引起的巨大骚动,“荣登”2018年度社会生活类十大流行语的榜单。去年8月非洲猪瘟首次登陆中国大陆,并迅速席卷辽宁、河南、江苏、浙江、安徽、黑龙江、内蒙古、吉林、天津、山西等多个省市。


在辞旧迎新之际,非洲猪瘟凭借着其引起的巨大骚动,“荣登”2018年度社会生活类十大流行语的榜单。去年8月非洲猪瘟首次登陆中国大陆,并迅速席卷辽宁、河南、江苏、浙江、安徽、黑龙江、内蒙古、吉林、天津、山西等多个省市。

新年伊始,黑龙江爆发了我国迄今最大规模非洲猪瘟疫情。

1月2日,农业农村部新闻办公室公布,黑龙江省绥化市明水县发生非洲猪瘟,该养殖场生猪存栏73000头、发病4686头、死亡3766头。此次疫情是迄今我国非洲猪瘟疫情中规模最大、损失最多的一例。另外,据行业专家表示,该养殖场的生物安全级别非常高,通过生物传播发生非洲猪瘟的几率较低。

疫情发生后,农业农村部立即派出督导组赴当地。当地已按照要求启动应急响应机制,采取封锁、扑杀、无害化处理、消毒等处置措施,对全部病死和扑杀猪进行无害化处理。同时,禁止所有生猪及其产品调出封锁区,禁止生猪运入封锁区。目前,上述措施均已落实。

农业农村部兽医局负责人介绍,非洲猪瘟是由非洲猪瘟病毒引起的家猪、野猪的一种急性、热性、高度接触性动物传染病,所有品种和年龄的猪均可感染,发病率和死亡率最高可达100%。世界动物卫生组织将其列为法定报告动物疫病,我国将其列为一类动物疫病。

就大众所关心的非洲猪瘟是否像禽流感一样会传染给人类?

农业农村部有关负责人作出回应,非洲猪瘟不是人畜共患病,病毒不会感染人。

那么,人吃了病猪肉会怎么样?

首先,非洲猪瘟病毒的存活能力非常强,能够在污染的环境中保持感染性超过3天;在猪的粪便中感染能力可持续数周,在死亡野猪尸体中可以存活长达1年;在冰冻肉中可存活数年,半熟肉以及泔水可长时间存活,腌制火腿中可存活数月,未经烧煮或高温烟熏的火腿和香肠中能存活3~6 个月……

但是,也不要因此而恐慌,因为非洲猪瘟病毒也有其致命的弱点——不耐热,所以,它在加工的过程中就已经死了。

中国肉类食品综合研究中心主任王守伟也曾明确表示,非洲猪瘟发现近100年来,全球范围内没有发生过人感染非洲猪瘟的情况,消费者完全不用担心食用猪肉感染疫病的问题。

非洲猪瘟在1921年的肯尼亚就首次发现了,自1921年以来,全球约有52个国家发生过AsF疫情或检测到病毒,其中包括31个非洲国家、17个欧洲国家和4个拉丁美洲国家。2018年成为了非洲猪瘟疫情登录中国的“元年”。

虽然非洲猪瘟病毒感染家猪病死率很高,但是,世界动物卫生组织(OIE)非洲猪瘟参考实验室Sanchez-Viscaino教授这样形容它:这种病毒就像老年人一样,行动缓慢。如果养殖场能坚持执行严格的生物安全防控措施,切断病毒的传播途径,就能够有效保护家猪不受侵害。

怕非洲猪瘟不敢吃猪肉? 农业部表态了

非洲猪瘟不是人畜共患病,不会威胁人类健康!这句话真想说三遍。自2018年8月3日我国确认第一起非洲猪瘟疫情至今,国内已有4个地方连续发生非洲猪瘟。非洲猪瘟给养猪业带来沉重打击,上千头生猪被捕杀,恐慌情绪在全国各地养猪行业蔓延。随之而来的是谣言四起,这直接引发民众对使用猪肉是否安全的顾虑。以至于养猪业人士自嘲,非洲猪瘟最大的传播途径是微信朋友圈。即便全国有4地发现非洲猪瘟疫情,有上千头生猪被扑杀,但
