Document: Swine products other than pork can also be involved in the spread through legal movements, like the 2012 introduction of PRRS into Switzerland in 2012, traced back to boar semen imported from Germany despite routine testing for PRRSV [77] .

Another example, although with no transboundary spread, took place during the 1997-1998 CSF epidemic in the Netherlands, when two artificial insemination centres became infected and provided potentially contaminated semen to as many as 1680 farms all over the country, out of which 36 became infected [37] .
