Boparan - comment
The impact of Avian Flu on Boparan is small so far. In Norfolk, four farms have reported cases and a handful of new control zones have been set up; the control zones around affected premises impose costs and will hit gross margins. The UK has not seen the outbreaks at anything like the scale of the US, but DEFRA is taking no chances. Avian Flu outbreaks occur every year but so far have been contained in the UK. If there were a significant outbreak of Avian Flu in the UK, the impact on Boparan would be severe.
