Vegetarian Society: Lab meat could be vegetarian
The Vegetarian Society has said it is "officially interested" in the possibility of lab-produced meat, but that it does not yet know enough about the process to welcome or condemn it.
Spokeswoman Liz O'neill did not rule out the possibility that in vitro meat could one day be sold under the Vegetarian Society seal.
She acknowledged the researchers' claim that cows are not harmed when stem cells are harvested, but said it remains unclear whether any other animal products are used in the process.
"We pleased to see people actually recognising ... that the amount of meat people eat is unsustainable ... [but] we would suggest a different path," she added.
