@Ganesh I would agree with you that the provenance of the ingredients used within our food chain are important to all, not just those who eat meat. Leaving it to the industry is a ridiculous strategy, and lends itself to fraud and corruption to maximise profit.
I would disagree on the point you make about British Beef though - Beef produced in the UK is tightlu regulated, because of the BSE crisis, and the authentication and testing much more robust - so consumers can have a lot more confidence that there has been no adulteration.
As consumers, we should all be entitled to have confidence in the provenance of our food sources and are free from adulteration with potentially hazardous substitutes ; The manufacturers and retailers owe us that much, but some seem perfectly willing to embark on fraud to make a profit.
