Lancaster MP Cat Smith has signed a parliamentary motion calling for CCTV cameras to be installed inside all UK slaughterhouses.
Ms Smith is supporting a campaign launched by Animal Aid, after five-years of investigating animal welfare breaches inside British slaughterhouses.
The national organisation has placed fly-on-the-wall cameras inside 10 slaughterhouses and found nine were breaking animal welfare laws.
The footage revealed slaughterhouse workers kicking, punching and beating animals in the head and face; picking them up by ears, legs and fleeces and throwing them; burning them with cigarettes; using the electrical stunning tongs to inflict painful electric shocks on the animals; and hacking away at the throats of fully conscious sheep.
“Failure to stun animals properly was also common and a serious breach of the law. Ms Smith said: “I have been appalled at footage emerging from some slaughterhouses of the mistreatment of animals.
“The behaviour exposed has been completely unacceptable and we must ensure this cruelty is stopped once and for all.”
Kate Fowler, from Animal Aid, said: “There is no excuse for the savagery we filmed inside British slaughterhouses, and yet it went on right under the noses of the vets who are stationed there to monitor welfare.
“Clearly, we need a more robust regulatory system, and CCTV – if properly monitored – can play an important part in deterring and detecting welfare breaches. “We are very grateful for the support of Ms Smith and her compassionate colleagues.”
