Hepatitis E Virus in Pork Production Chain in Czech Republic, Italy, and Spain, 2010

Abstract

Processing does not substantially abate endogenous virus.

The Incidence of Hepatitis E Virus in Domestic Pigs

“…Very low occurrence of RNA HEV (3 %) was observed in faeces samples collected in a Czech slaughterhouse, similarly to clinically healthy pigs [4]. Besides Czechia, swine HEV was detected and characterized in neighbouring Hungary.…”

“…At the same time swine HEV has been detected and characterized in such neighbouring countries as Hungary and Czechia [8,4]. Domestic pigs are believed to be an important source of zoonotic transmission of HEV-3 and HEV-4 and they are responsible for sporadic human hepatitis E cases worldwide [17].…”

Hepatitis-E-Virus

“…In Län-dern wie Japan, den USA, dem Vereinigten Königreich und Deutschland wurde HEV in Schweinelebern oder anderen Fleischprodukten nachgewiesen, die käuf-lich erworben und als Nahrungsmittel freigegeben worden waren [17,32,[121][122][123][124]. Zudem wurde über HEV-Übertra-gungen durch Figatellu in Frankreich und von HEV in Wurst in Spanien berichtet [115,116,123]. Diese Befunde weisen darauf hin, dass HEV durch HEV-kontaminierte Nahrungsmittel auf den Menschen übertragen werden kann.…”

Hepatitis E Virus

“…The detection of isolated IgM suggests that the samples came from pigs that had been infected recently and thus may contain infectious virus, for example in the liver. In countries such as Japan, the USA, the UK and Germany, HEV was detected in pig liver or other pork products that were released for consumption and commercially available [17,32,121,122,123,124]. Furthermore, HEV transmission by figatellu was observed in France, and HEV was detected in sausage in Spain [115,116,123].…”
