After this time the statutory
regulations were lifted on approval from the UK governments
Department for Environment, Food and Rural Affairs
(Defra). Any sites known to have supplied, or received susceptible
species to or from a confirmed SVC positive site
were also tested by the same methods as suspected sites.
Since 2007, no further cases of the disease in open water
systems (fisheries and farms) were observed, and in 2010
the UK achieved disease freedom for SVC (EC Decision
2010/221/EC). However, in 2011 there was a single isolated
SVC case in an enclosed fishery (a lake not connected
to the river network). This was successfully eradicated and
spread prevented through the prompt culling of fish stocks,
the disinfection and fallowing of the site, allowing the UK
to retain its SVC free status.
