According to DEFRA last zoonose report, Campylobacter continues to be the most commonly reported human gastrointestinal pathogen. After a general upward trend over the past 10 years, the number of laboratory reports of Campylobacter fell across the UK during 2013. There were 66,575 reports in the UK , a decrease of 8 % from 2012 . There were 19 foodborne outbreaks of campylobacteriosis reported in 2013, which is a significant increase on the eight reported in 2012. Fourteen outbreaks were associated with the consumption of poultry, of which nine were chicken liver parfait.
In relation to Hepatitis E, in England and Wales the majority of hepatitis E virus (HEV) cases in people are non - travel related and present as sporadic disease. Since 2010, the numbers of confirmed hepatitis E cases have increased year on year with 691 cases reported in 2013, a 19% increase since 2012. The numbers of travel - related cases have remained relatively stable over the years. Therefore the substantial increase observed since 2010 is due to an increase in indigenously acquired cases, with 69% of cases assessed as non - travel associated or indigenous. The substantial increase in indigenous cases in England and Wales appears to be due to the emergence of a different HEV phylotype (genotype 3, clade 2), not commonly observed in England and Wales prior to 2010. Thus there are currently two concurrent outbreaks contributing to the burden of disease nationally : clade 1 virus, which has been the cause of hepatitis E cases since 2003; and clade 2 virus which emerged more recently and accounts for ar ound two thirds of cases in 2013 . The multi-partner collaborative pig abattoir survey, which was undertaken to better understand the possible role of infection in pigs on human disease incidence, showed that 93% of 640 pigs tested were seropositive at slaughter, with 6% actively infected with HEV, as shown by the presence of detectable plasma HEV RNA. The viral load was sufficient to identify the virus from a small number of pigs as genotype 3, clade 1. This is not the clade of virus associated with the substantial increase in indigenous cases in people since 2010 and so the cause is unlikely to be meat from UK pigs.
