Dear Editor,

Increasing number of hepatitis E virus (HEV) infection has been described in industrialized countries, with infection occurring as a sporadic disease, usually associated with travel to endemic regions or small outbreaks due to ingestion of contaminated food or water. More recently some cases were found to be associated with zoonotic transmission, particularly through consumption of uncooked deer, wild boar or pig meat, or through occupational contact with faeces or excrements from infected animals (Berto et al.2012; Carpentier et al.2012; Ruggeri et al.2013). Portugal has a long history of hunting, with hunted animals being used for human consumption as meat or local products, some of them consumed raw. The evaluation of HEV infection in those animals is, therefore, crucial to assess the potential risk of its zoonotic transmission to humans.

Despite HEV infection is well characterized in Portuguese pigs (Berto et al.2012), the information on the prevalence of HEV...
