Outbreak of Bacterial Kidney Disease in Yorkshire and Hampshire Trout Farms

UK - The presence of Bacterial Kidney Disease (BKD) has been confirmed trout farms in Hampshire and Yorkshire.

Outbreak of Bacterial Kidney Disease in Yorkshire and Hampshire Trout Farms - UK - The presence of Bacterial Kidney Disease (BKD) has been confirmed trout farms in Hampshire and Yorkshire.

The presence of Bacterial Kidney Disease (BKD) has been confirmed in two trout farms in Yorkshire and Hampshire.

Defra has issued an Order under the Diseases of Fish Act 1937, prohibiting all movements of fish to and from the infected Fish Farm.

In both caes, the disease was found in a trout sample taken as a result of an investigation into an outbreak at another farm. Whilst the disease is considered serious and notifiable under EU law, it is not widespread in Great Britain and occurs only sporadically.

BKD has no implications for human health.

Further Information

The Diseases of Fish (Designated Areas) (England) (No. 5) Order 2006 restricts the movement of any live fish or live eggs of fish into or out of the designated area without the prior written consent of Defra.

The designated area's are Harome Trout Farm, Rye House Farm, Harome, York, North Yorkshire, and Greatbridge (Test Valley Trout), The Island, Greatbridge, Romsey, Hampshire.

Further information on BKD and other serious freshwater diseases can be found on the Defra website in its Combating Fish Disease publication. Our sister site, www.efishbusiness.co.uk also provides a wealth of information on fish health matters.

To organise a fish health inspection on suspicion of an outbreak, contact the CEFAS Fish Health Inspectorate on 01305 206673/74 or by sending an email to: fish.health.inspectorate@cefas.co.uk

This new DAO came into force on 18th July 2006.

Fish infected with BKD may display a number of characteristics including protruding eyes, a swollen abdomen, pale anaemic gills and haemorrhaging at the base of the gills. Anyone suspicious of a possible outbreak of BKD or have noticed signs similar to these, should immediately contact the Fish Health Inspectorate at CEFAS Weymouth.

BKD can cause large numbers of mortalities in both farmed and wild salmon and trout. It was first recognised in Atlantic salmon on the River Dee, Scotland in the 1930s and in 1976 there was the first notable case of BKD in farmed rainbow trout. Whilst the disease is considered serious and notifiable under EU law, it is not widespread in Great Britain and occurs only sporadically.
