I saw the story online. And I actually read it. It didn't seem to me like it was over-hyping or downplaying it... just reporting the facts, which is sorely missing in most of today's "news reporting".
It wasn't from the feed, and it can happen as a mutation randomly--not from a "source"-- and apparently that is what this case was. One of the scientists gave the odds of it happening again in the near future and it was likened to some sort of astronomical odds of a rare space event happening. And this cow was randomly tested, and was slated to go to a rendering plant, not into the food chain for humans.
But yeah... it showed no symptoms, so that could be rather scary.
I think the "story" isn't so much this particular case, but rather they should do a looky-loo into the entire US beef trade. How exactly do they test for this, and how often, etc. Do they use the most accurate methods of testing, etc?
No, I am not surprised there wasn't more coverage. There wasn't really much of a story, unless, as I said above, they do a full background on the food supply in agriculture here in the USA.
That, and there was other news... did you see that NBA concussion causing elbow?!
