In September 2009 a single outbreak was detected in the same region, following illegal movement of infectious material from the affected regions in the Caucasus. The outbreak was quickly stamped out and surveillance revealed no further spread. This recent outbreak is concerning as it could indicate a wider problem not only in disease distribution but also in biosecurity and compliance with disease reporting.
The proximity of the location of the pig carcases to St Petersburg and the St Petersburg ports (one of the busiest Russian port complexes, handling one quarter of all foreign trade cargoes) as well as to the EU border is concerning. This has led the EU to highlight the requirement for vehicles transporting pigs to and from Russia into the EU to be adequately disinfected. However, we would also like highlight that any transport for other trade goods coming through an infected region could potentially carry infectious material if not disinfected, whether by road or by ship.
