Overview

At the time of writing the UK poultry scene is dominated by the outbreak of highly pathogenic Avian Influenza H5N1 in a turkey flock in Suffolk, and the debate on the similarity between the Suffolk and recent Hungarian virus isolates. Debate has also been ongoing in the poultry press on the potential role of migratory birds in spreading disease and on the continued importance of biosecurity.

The opportunity for disease spread from wild or feral to domestic birds was well illustrated by the Newcastle disease outbreak in partridges in Scotland in October, and spread by wild birds was also implicated in the LPAI H7N3 outbreaks in Norfolk in April (Quarterly Report April-June 2006).

Two further outbreaks of Fowl Typhoid (Salmonella Gallinarum) have been confirmed during the year, in unrelated flocks. The continued prevalence of Mareks disease in both vaccinated and unvaccinated birds has been highlighted in this year’s Reports, and the causes and prevention of vaccine breaks were summarised in the January - March Report. Data is presented showing a continued decline in Necrotic Enteritis in conventional broilers, and of blackhead (histomoniasis) in turkeys.

The statistics on page 2 show a decline in the numbers of all four categories of chicks placed, both since the last quarter and compared with the fourth quarter of 2005, and there was an overall decline in UK poultry meat production of 2.45% since last year. These figures are impacted by economic factors and it remains to be seen what the trends will be in 2007.
