Religious slaughtered meats

Having recently discovered exactly what religiously slaughtered meat entails, I do not want to ever unwittingly consume this barbaric foodstuff. How can I protect myself from unwittingly buying this or do I need to become a veggie. On nearly all products you buy it tells you the calorific contents etc, but does not tell you how it was slaughtered. Having written to places like Tesco, Asda who sell this, I got no assurance that the unlabelled meat I can buy will not be halal.
Although all slaughter is horrible and yes imguilty cos i eat meat,although i am eating more quorn meat substitute, to slaughter an animal whilst fully conscious whithout stunning and being left to choke in its own blood for up to 10 mins is barbaric.

I THINK YOU WILL FIND DEFRA, RSPCA, BVA TO NAME A FEW PREFER ALL ANIMALS TO BE STUNNED. PLEASE DO NOT CLASS ME AS AN ANIMAL ACTIVIST I AM MERLEY A PERSON WHO CARES ABOUT ANIMAL WELFARE!!

Religious slaughter - DEFRA
There are long-standing provisions in our law which, subject to specific requirements, permit the slaughter of animals without stunning to meet Jewish and Muslim religious requirements. Whilst the Government would prefer that all animals were stunned before slaughter, it recognises the needs of certain communities and accepts the importance which they attach to the right to slaughter animals for food in accordance with their beliefs. Religious slaughter must be carried out only in approved red meat slaughterhouses or, in the case of poultry, in approved or other officially regulated slaughterhouses (see guidance about religious slaughter for the Muslim community). We attend regular meetings with representatives of the Muslim community to address any areas of ongoing concern. These meetings are chaired by the Food Standards Agency. We also hold occasional meetings with Jewish organisations.

The Farm Animal Welfare Council has concluded that slaughter without pre-stunning does cause suffering to the animals.

WHY IS RELIGIOUS SLAUGHTER WORSE THAN OTHER SLAUGHTER?

While we fully know that all slaughter is extremely traumatic for animals, we believe that religious slaughter is even more so. The animal's throat is cut and it is bled to death; it is fully conscious throughout this process. It can take up to 16 minutes for the animal to die.

A study* showed that on a scale of 100 the agony of death by:
Throat Cutting (equal to Halal or Kosher methods) = 86. The 2nd worst death except for being burnt to death by fire
Gun Shot to Head (equal to the UK's legally required method of stunning) = 13.

Thanks Bennjammin for your reply, even kellogs and campbells now cater halal style. It seems this country is all for pleasing the minority 4% but the remaining 96% have to shut up and put up. I am not even replying to people who want to just argue as to how do I no it pains the animal more during halal slaughter, I mean it's just obvious!!!
I am now looking at a private law suit as our human rights have been violated. I have been speaking with Sikhs on this subject and their religion strictly forbids them to eat this form of meat, but unfortunatley the government does not even consider their religion!
I am facebook members with scotland for animals and follow the HSA.
Our facebook group and petition is growing daily and we will not stop until this barbaric and outdated practice is stopped in the UK.
