Torque teno viruses (TTV) are icosahedral, single-stranded circular DNA viruses infecting several vertebrate species. Currently, these viruses are considered non-pathogenic although they are suggested to be co-factors in several diseases. Recently single-stranded circular DNA viruses have been found in human faeces. Considering the consumption of pork meat products and the ubiquitous nature of swine TTV (Torque tenosus virus, TTSuV), the human population is frequently exposed to these viruses. To determine if TTSuVs could be delivered through food, human faecal samples were analysed for their presence. Indeed, the results of this study show that up to 25% of faecal samples were positive for known TTSuVs by PCR and sequencing. Additionally, all commercially available pork products purchased in Spanish supermarkets contained DNA of TTSuV. © 2013 Elsevier B.V.
