SIR - Wendy Lawson (Worcester News, February 6) should know it is no only halal slaughterhouses where animals are horribly abused.

Animal Aid's undercover investigation found breaches of animal welfare laws in eight of nine randomly chosen UK slaughterhouses.

Anyone who cares about the treatment of animals in all slaughterhouses should go to Animal Aid's website www.slaughterhousecctv.org.uk to sign the petition calling for mandatory CCTV in all slaughterhouses. Many of the major supermarkets are already insisting on CCTV in slaughterhouses that supply to them so it can be done.

Please take five minutes to sign the petition to persuade the government to get CCTV in slaughterhouses.
