Cavendish, I didn't take offence a bit, sorry if I sounded as though I had!
There may well have been a bit of a 'tone' in what I wrote - but aimed at exactly what you describe; we know the public has no real knowledge of what all these schemes are and even if they do think they do, in many cases the scheme as implemented doesn't in fact address the issues it was set up to address. (Sound of me on one of my hobby horses.)
FABBL (Farm Assured British Beef & Lamb) is the scheme behind the Little Red Tractor logo. It is supposed to give consumers confidence that the food they are buying is British, safe and has been reared and slaughtered to high welfare standards.
In fact, in the lifetime of the scheme, almost everything that was originally an additional requirement on the farmer is now part of the general legislation in any case, so that all FABBL really does is audit farmers rather more thoroughly and very much more frequently than Defra does in the first place. (Note I am not au fait with Scottish legislation nor any Welsh specifics so can speak only for England really.)
Our annual FABBL inspection takes about 2 hours, sometimes more. The inspector will check our animal handling facilites and accommodation, a random selection of animals for condition and identification, check that everyone involved in handling / treating the stock is suitably qualified / experienced, spend quite a bit of time checking through medicine records and the medicine cupboard, discuss some aspects of animal health with us (eg, lamb castration, calf de-horning) and check other procedures - for instance 'manure management' (where we do and don't spread muck and artificial fertiliser and when), broken needle policy - and equipment (eg trailer.)
Some supermarkets pay up to 5p / kg deadweight less for non-assured lambs. 'FA', 'SA' or 'NA' (for FABBL, Scotch Assured or Not Assured) comes up on the display boards in all our local marts. Whether or not buyers don't buy or pay less for NA stock I really couldn't say.
