Bacterial Kidney Disease suspected at central Norwegian farm

Bacterial kidney disease (BKD) is suspected at a site in the Norwegian south west region of Møre and Romsdal.

BKD  is a serious problem for salmon farmers and can lead to heavy mortality among both farmed and wild salmon with outbreaks resulting in  major financial losses.

The  possible  outbreak is at a location where Hofseth Sea Farming and Ewos Innovation cultivate salmon and rainbow trout.

Anyone who travels in the area and carries out activities related to fish farming will now have to show the necessary care so that the spread of any disease can be  avoided.

Facilities in the area must have a particular focus on BKD at all health checks. It is important to prevent further spread between facilities or to wild fish through fish, equipment and boats.

It seems that an autopsy, showed changes compatible with BKD had been discovered. Analysis of kidney tissue for PCR showed detection of a bacterium compatible with the disease.

The Norwegian Food Safety Authority  said it plans an immediate inspection of the plant to take samples to confirm the diagnosis.

In order to limit the spread of infection, restrictions have been imposed on the site, including a ban on moving fish, roe and milk without special permission. The exception is when fish is transported to the slaughterhouse.

If the suspicion is confirmed, the Norwegian Food Safety Authority can order the emptying of the premises, possibly parts of the premises.

Measures are also being taken to protect wild salmon in the area.
