I would say  that one needs to make sure the brains/eyes come from organic(or naturally-reared),grassfed cattle:-

 As long as that's the case, though,  and the cattle aren't  fed on used animal parts, it's perfectly safe - I've been eating a wide variety of organ-meats including brains for years with no issues(as far as I can tell!).

Thus, unless you are certain about where your beef/mutton etc. comes from (and that they are not feeding ground up animal byproducts), you should avoid these tissues - brains and eyes particularly.  > I would not trust large commercial producers for this type of food (although trusting them for the relatively safe tissue is probably hazardous as well - for other reasons).> Lately I've been sticking to local, pastured beef and bison.> I don't care for organ meats.  They taste too strongly for my delicate palate (but oh how hard it is to give up diet coke - lol).
