In view of the epidemic theft of horses; Accountability of abattoirs is essential.
For example - scrapyards by law now insist on name, address and form of ID before paying the for scrap by cheque. This creates a paper trail and has vastly curtailed some of the criminality involved in scrap dealing.
This is an essential step to take with regard to abattoirs. Cash for 'meat' must stop. A paper trail will make the theft of horses much less attractive.
Why all equines aren't chipped like our domestic dogs and cats is beyond me, they should all be traceable and slaughter houses should not accept them with out the correct paperwork although how they would action that is debatable.
