An RSPCA spokesman added: ‘The public have a right to know how their meat is produced. Many people are extremely concerned about animal welfare. What The Mail on Sunday has discovered shows that people are not being kept informed. The key to a more humane death for these animals is that they are stunned before slaughter.’

Is that actually true though?

In 1978, a study incorporating EEG (electroencephalograph) with electrodes surgically implanted on the skull of 17 sheep and 15 calves, and conducted by Wilhelm Schulze et al. at the University of Veterinary Medicine in Germany concluded that "the slaughter in the form of a ritual cut is, if carried out properly, painless in sheep and calves according to EEG recordings and the missing defensive actions" (of the animals), but that when Captive Bolt Stunning (CBS) was used, which is common in normal (non-kosher) slaughtering,[51] "For sheep, there were in part severe reactions both in bloodletting cut and the pain stimuli."
