Have you given some serious thoughts to the massive cost of this?

If 10 supermarkets selected one meat product at random every 3 months,
that would be 40 tests a year.

I think that nowadays some automatic procedures would be available to
identify anomalous DNA, and even if each test cost 1000 pounds, the
total of 40,000 per year would be an unnoticeable drop in the ocean for
the economy.
