I have heard people describe jhatka as killing painlessly with one stroke. In countries like the UK, the chances of being able to kill an animal with a kirpan or something with one swift blow to the neck, everytime you want meat, are pretty slim. So is it still considered jhatka if the animal has been killed in a slaughterhouse? I've seen animal slaughter on TV and it doesn't look swift and although there is only one cut, the animal is still given an electric shock or is hit with a bolt gun before the actual slaughter, so it may still be painless, but is that kind of meat still allowed for Sikhs?
