if you don't eat beef.It's as simple as that.
then it is safe to eat McDonalds burgers
According to docs, one gets mad cow disease if one consumes the brain or the spinal cord of the infected animal.
And you think that some spinal cord cells NEVER end up in processed beef?????Just like down cows don't end up being processed for human consumption.Just like cows are not suppose to be fed feed mixes meant for other animals like chickens, because they contain cow by-products.
