I agree with all the above. I have voluntarily bought, cooked and eaten horse, but not in the UK.
I am concerned only because, if quality control is this lax, what else is in these products that shouldn't be... and was the horse meat fit for consumption? I am also concerned that the mis-representation means that those with religious objections to certain meats have probably been eating them all along if they buy processed products.
Like AMLightfoot, we buy and eat few processed meat products. I even buy sausages from my local butcher and he makes his own. I believe his ingredients list.
