There is an outbreak of EFB in Montgomeryshire.
At time of writing I am aware that at least two apiaries are affected. The SBIs are investigating the outbreak and actively checking apiaries which they suspect are most at risk either because of location or potential contact with infected bees and/or beekeeper's equipment.
I will try and update this as news comes in. See also BeeBase for more information. The link takes you straight to the stats page where you can see that there have been 25 cases in Powys as a whole!
