Can Brits learn from US religious perspective on food ethics?

Interesting thoughts in The New York Times on the importance of ethics in kosher food, but from a religious perspective.

Rabbi Herzfeld might be referring in this instance to the problems at Agriprocessors, but I think his argument holds true for the consumption of all kosher meat. As we head into the Fast of Av, it's mental nourishment for those of us in the UK that are complicit in putting up with - or should that read encourage? - bad practices.

I'd like to see a British Orthodox rabbi come out with some equally trenchant views.
