Trevor Waldrom wrote about the slaughtering of animals for meat and animal experiments and asked for views ("Views sought on how we slaughter animals", March 26).
Mr Waldrom commented that operators in a slaughterhouse said that "there was no pain to the animals because they were stunned prior to death".
Dr Hillman, from Surrey University's Department of Physiology and Neurobiology, says: "Stunning is believed to be humane because it is thought that the animals do not suffer pain or distress. This is most certainly untrue."
The Animal Welfare Council concluded that stunning "is not sufficient to render the animal insensitive to pain".
Mr Waldrom mentioned slaughter which does not include stunning. I presume he was referring to halal.
According to recent press reports, halal meat is sold in many supermarkets and served in fast-food chains, hospitals, schools and pubs without consumers' knowledge and "most lamb imported from New Zealand by British supermarkets has been slaughtered according to Muslim law".
My view is that no method of slaughtering animals can be considered humane.
