Best way to kill lab animals sought

Abstract

"There are lots of assumptions made about the humaneness of various techniques for euthanizing animals," says Penny Hawkins, deputy head of the research animals department at the Royal Society for the Prevention of Cruelty to Animals, a charity based in Southwater, UK. Widely used guidelines on animal euthanasia from the American Veterinary Medical Association (AVMA) in Schaumburg, Illinois, were updated earlier this year, in part to adapt to changes in the animals used in labs, with zebrafish guidance one of the additions.
