I think that they wouldn't have different labelling because essentially the end product is still the same, it's just that the way it got there was different. I would rather it be labelled simply because it would be easier for someone wanting halal meat to just see it on the label and buy it instead of having to find someone to ask them and then deal with the vague blank look on their face when they say they don't know.

I'm not bothered by eating meat that is halal or kosher because I don't have a religion so to me, meat is meat.

A few years ago here there was a huge influx of o/s workers during the construction phase of the Cowal Gold Mine and they wanted halal meat and the local abbatoir actually arranged for someone to come and do a halal slaughter for them. Halal meat isn't exactly the easiest thing to come by out here LOL.
