Switzerland is to ban imports of live pigs and pork from several EU countries in a bid to stop an African swine fever outbreak from reaching the country, focus-fen.net reported. Imports from Bulgaria and Romania and some parts of Latvia and Croatia will be banned as of Wednesday, Swiss food safety authorities said on Tuesday. All live pigs and boars, their meat, sperm, eggs and embryos will be covered by the ban, according to the decree. Posing a lethal threat to commercial pig farms, African swine fever has spread throughout the Balkans, the Caucasus and Russia since 2007, and is endemic to areas of Africa, according to the United Nations’ Food and Agriculture Organisation (FAO). There is no African swine fever virus in Romania and no pork products were exported to Switzerland either this year or in 2013, announced the National Sanitary Veterinary Authority for Food Safety (ANSVSA). “All the Swiss authorities did was to announce they implemented the European legislation through national normative documents. Subsequently, trade goes on under the same circumstances, as Switzerland observes the requirements of the European legislation,” runs an ANSVSA press release.
