Canada had a mishmash of organic standards until very recently, when the organic food industry was threatened with being shut out of the fast growing, lucrative European and Japanese organic food markets if they didn't get their act together. The government was perfectly willing to go on diddling forever; thankfully, they were prodded by the market's invisible hand.
Another Canadian example is Maple Leaf Foods, which had a listeriosis outbreak in one of its plants and had to recall a bunch of meat products. They certainly attended to the PR side of things, but they cleaned up the problem.
