臺灣PEDV最有可能的原始源頭;英國的不列顛全國養豬協會對該國農民提出有關中美新型PEDV的防疫呼籲
重點是
1. 不論國內國外的來訪者皆需三天以上沒有接觸豬隻
2. 確實做好相關生物安全措施

Pig association calls for help keeping porcine epidemic diarrhea out of Britain

New PEDV strains in US, China create concerns in Europe
Release Date: Monday, July 22, 2013

Britain's National Pig Association is asking UK pig farmers to help keep a new strain of porcine epidemic diarrhea virus (PEDV) out of Europe. The virus has been present in Britain in a mild form for more than 40 years, but new strains in China and the United States are wiping out whole generations of newly-born pigs - and there is no effective treatment.
It is essential the new PEDV strains are kept out of Britain, says National Pig Association. It is calling for everyone involved in farming to adopt a number of extra-precautionary measures.
•Only absolutely essential visitors from overseas should be allowed onto pig farms and they must have entered Britain at least three days before the visit. Only unit clothing and footwear should be worn on the unit.
•If you are returning from overseas yourself, allow three days before considering yourself "pig-free".
•Ensure all your staff and colleagues are aware of the risks posed by the new strains of PEDV and that they comply with all biosecurity measures if visiting British pig units.
In addition to its general advice to everyone in British agriculture, the National Pig Association is advising all pig-keepers to contact their veterinarian if they see unusual clinical problems with diarrhea, particularly in piglets.
Producers should also work with their nutritionist, feed supplier and vet to check the provenance of nutritional products used on their farm, and consider whether any might pose an unacceptable risk.
The association says that as a matter of principle no meat products should ever be allowed onto pig units, because of their potential to introduce serious diseases such as foot-and-mouth disease, classical swine fever, African swine fever, and perhaps the new virulent strains of PEDV.
NPA is asking all to run a critical eye over all their current biosecurity measures and see where they can be improved. It is also urging genetics companies to think carefully before importing live pigs from the States for the time being, regardless of the high level of biosecurity usually attached to such shipments.
If the new acute strains of PEDV spread to Britain they could have an impact every bit as bad as postweaning multisystemic wasting syndrome, which arrived in Britain from mainland Europe about 13 years ago and contributed to a halving of the national herd, only coming under control in recent years, following the introduction of highly effective vaccines.
The current outbreak in the US, which is still spreading, is causing losses of up to 100 percent of affected piglets and has been reported on over 200 units in 13 states since May. The virus from the outbreak in the US is said to be 99.4 percent similar to an outbreak in China which has killed more than 1 million piglets since October 2010.

根據多位資深且仍在現場工作的西歐獸醫師的回報
PED及TGE在歐洲(特別強調最近的病例在2000年代中期的義大利),已........年不見了
因此臺灣PED的問題應該類似此種疫情

而TGE在呼吸道冠狀病毒引入後,就久未謀面了.西歐也是相似的疫情
好消息,又有一個疫苗不必接種了

消化道疫苗中投資報酬率最佳的應該算是
母豬用的大腸桿菌類毒素不活化疫苗
