CFIA不能確定飼料引發(fā)PED

　　新聞發(fā)布日期：2014年3月5日

　　由加拿大食品檢驗(yàn)局（CFIA）進(jìn)行的科學(xué)測(cè)試無(wú)法確認(rèn)含有血漿的飼料與加拿大爆發(fā)的豬流行性腹瀉（PED）的相關(guān)關(guān)系。

　　As reported on February 18, the CFIA conducted a bioassay study on US-origin porcine blood plasma used in feed pellets produced by Grand Valley Fortifiers.

　　根據(jù)2月18日的報(bào)道，CFIA對(duì)Grand Valley Fortifiers公司使用美國(guó)血漿蛋白制成的顆粒飼料進(jìn)行了生物測(cè)定。

　　The study demonstrated that the porcine blood plasma in question contained PED virus capable of causing disease in pigs. However, the study could not demonstrate that the feed pellets containing the blood plasma were capable of causing disease.

　　這項(xiàng)研究表明這些問(wèn)題血漿含有能夠?qū)е仑i生病的PED病毒。然而，這項(xiàng)研究不能證明含有血漿的顆粒飼料是能夠引起疾病。

　　In line with our commitment to science, the Agency will continue to analyse feed and feed ingredients, as well as epidemiological information gathered during the investigation, in order to verify that CFIA controls continue to protect Canadian livestock. In addition, the CFIA will examine any new lines of enquiry related to feed that may emerge, in particular from ongoing testing in Canada and the US.

　　根據(jù)對(duì)科學(xué)的責(zé)任，該機(jī)構(gòu)將繼續(xù)分析飼料和飼料成分，以及在調(diào)查過(guò)程中收集到的流行病學(xué)資料，以確認(rèn)CFIA控制可繼續(xù)保護(hù)加拿大的家畜。此外， CFIA將研究調(diào)查與飼料生產(chǎn)相關(guān)的任何可能出現(xiàn)的線索，尤其是正在加拿大和美國(guó)進(jìn)行的測(cè)試。

　　In response to the positive test results in porcine blood plasma, the CFIA:

　　為了回應(yīng)豬血漿蛋白的陽(yáng)性檢驗(yàn)結(jié)果，CFIA做出:

　　·activated its National Emergency Operations Centre (NEOC) to coordinate the feed investigation;

　　·followed up with farms that received the affected feed to confirm the voluntary withdrawal was effective;

　　·provided science-based guidance on disposing of potentially affected feed;

　　·worked closely with US officials to confirm that none of the affected plasma was shipped to other pig feed manufacturers in Canada

　　·啟動(dòng)國(guó)家緊急行動(dòng)中心（ NEOC ）協(xié)調(diào)進(jìn)行飼料的調(diào)查;

　　·跟進(jìn)所收到的問(wèn)題飼料，以確認(rèn)自愿回收是有效的;

　　·提供處置問(wèn)題飼料的科學(xué)指導(dǎo)依據(jù);

　　·與美國(guó)官員密切合作，確認(rèn)沒(méi)有問(wèn)題飼料可傳給加拿大的生產(chǎn)商。

　　The CFIA's investigation also included sampling and testing of feed, plasma and other feed ingredients from various Canadian and US sources associated with farms in Canada on which PED has been detected. All test results on these samples were negative for PED.

　　該CFIA的調(diào)查還包括采樣，測(cè)試飼料，血漿及其他飼料原料，這些來(lái)自加拿大和美國(guó)原料樣品來(lái)自加拿大爆發(fā)PED的農(nóng)場(chǎng)。這些樣品的所有測(cè)試結(jié)果均為陰性PED。

　　The feed investigation was triggered on February 9, after Ontario Ministry of Agriculture and Food (OMAF) testing found that US-origin porcine blood plasma used in feed pellets produced by Grand Valley Fortifiers contained PED virus genetic material. As a precautionary measure, Grand Valley Fortifiers voluntarily withdrew the potentially affected feed pellets from the marketplace.

　　安大略省農(nóng)業(yè)部和食品部（ OMAF ）測(cè)試發(fā)現(xiàn)Grand Valley Fortifiers公司的豬顆粒飼料中使用的美國(guó)源豬血漿蛋白粉含有PED后，于2月9日開(kāi)始了飼料調(diào)查。為慎重起見(jiàn)，Grand Valley Fortifiers公司自愿收回了市場(chǎng)的潛在問(wèn)題顆粒飼料。

　　Samples of both the feed pellets and the porcine blood plasma ingredient were submitted to the CFIA's National Centre for Foreign Animal Disease (NCFAD) for further testing. It was confirmed that both the blood plasma and the feed pellets contained PED virus genetic material; however, the bioassay study was required to confirm if this genetic material could cause illness in pigs.

　　這些顆粒飼料和豬血漿蛋白原料均提交給CFIA國(guó)立外國(guó)動(dòng)物疾病中心(NCFAD)。據(jù)證實(shí)，血漿和顆粒飼料均含有PED病毒遺傳物質(zhì)，然而，需要進(jìn)行生物測(cè)定研究，確認(rèn)該遺傳物質(zhì)是否能引起豬生病。

　　PED can spread rapidly through contact with sick animals, as well as through people's clothing, hands, equipment, boots, and other tools contaminated with the faeces of infected animals. Therefore, considering the characteristics of PED virus and how it spreads, adhering to good biosecurity protocols remains the best measure to prevent further introduction or spread of this disease in Canada.

　　PED能通過(guò)與患病動(dòng)物接觸，以及人的衣服，雙手，設(shè)備，靴子和其他沾染感染動(dòng)物糞便的工具迅速傳播。因此，在考慮PED病毒的特性以及它是如何傳播時(shí)，遵守良好的生物安全協(xié)議，防止疾病進(jìn)一步的傳播仍然是加拿大最好的措施。

　　微評(píng)：明尼蘇達(dá)大學(xué)的一項(xiàng)新研究表明，豬糞和水也可能是PED傳染源。PED病毒的感染劑量非常低，甚至只要10-8。PED病毒在低溫的泥漿和濕飼料中28天仍能存活，在新鮮糞便、飲用水和干飼料中能存活1-2個(gè)星期。因此，我們?cè)诜治黾膊?lái)源的時(shí)候，應(yīng)從所面對(duì)的材料追蹤查詢，科學(xué)驗(yàn)證，方能對(duì)癥下藥，手到病除。
