CCTV to cover all areas where there are live animals or slaughter taking place is one requirement which is always pointed at. However, these smaller premises may wish to benefit from minimal attendance by FSA staff, in which case reviews of this footage would be required to ensure animal welfare.
@Smith31 may be able to help us with where relaxing legislation would be of practical help.
Its not just legislation, the big abattoirs are working for paper thin margins, the well established mid sized family owned abattoirs are doing extremely well, most made a fortune from the BSE cull so are mortgage free and on a very strong footing.
From a business viewpoint, small abattoirs using minimal automation and machinery simply can't compete. With wages every rising, combined with a shortage of skilled slaughtermen, unfortunately I can't see a profitable future for them.
My personal opinion is that in comparison to building a new abattoir there are far better ways of blowing money i.e race horses, tall slim horsey blondes, shiny machinery, out of warranty Range Rovers.
The best thing about owning an abattoir is when you shut it down the Council planning officers bend over backwards to award you planning permission to build houses, as they are sick of the locals complaining.
