Farmed Fish May Eat Your Brain?

I thought that this was an interesting article at Natural News, basically identifying a link with Creutzfeldt-Jakob disease (vCJD) (aka mad cow disease) and how it's finding it's way to farmed fish. I try to avoid farmed fish anyhow, since I've read it's generally not as healthy (with some exceptions, such as the farmed fish sold by Whole Foods, which have higher safety standards) but all the same, I prefer to purchase fish that's caught wild. Walmart, of all places, sells a decent wild salmon fillet for about $6, which isn't bad considering it's salmon, it's wild, and it's a large enough portion to feed the fam.
