I eat meat. I would want to know that the meat that I am eating has been slaughtered according to a humane standard. I do not think that such a stance is hypocritical.
There are abbatoirs in the UK ANSA - Association of Non-Stun Abbatoirs- who have an exemption from stunning on religious grounds.
Although Halal allows for pre-stunning, Kosher does not, and for most muslims that i have heard, they assume that halal means non-stun too.
There was an animal welfare report from 2004 which suggested that a large % of the animals killed in the halal fashion in the UK were pre-stunned, which is all well and good, although I have not seen the report myself, but as a consumer I want to be able to make that distinction for myself.
And as we have all seen with the recent scandal of adulteration of beef with horsemeat, how do we know what goes on in other countries abbatoirs?
I do not think that Tesco are acting in the consumers best interests, if all their NZ lamb is slaughtered in the halal fashion, but not marketed as such.
So I no longer by any meat products from a supermarket but from a local butcher who makes use of a local abbatoir.
