Back here, I told you I was reading Fast Food Nation. Well, I finished.
Now, I'm not sure what the legalities are around quoting a book in a blog are, so I won't bother quoting, but I will refer to the book for one interesting parallel.
In the afterword, it discusses the early belief that bovine spongiform encephalopathy (BSE, or "mad cow disease") could be spread when ruminants ate the meat of infected ruminants, and that consumption of BSE-tainted beef was dangerous to humans. This warning went back as far back as 1986.
The short of that story was that when it was initially proposed, it was dismissed; sold as "junk science".
Governments indicated that there was nothing to worry about; that enforcing regulations based upon this would cause the agriculture industry to fail.
Does that sound like a story you've read before?
