Here is a question, how could it spread to so many farms in so many countries so quickly? It is spread between animals, if people had bought animals
from a farm that was infected, that would show up quickly as the reason; but, it did not. What would be used in common at different farms in different
countries at the same time, I am guessing some feed product or some vaccine or medicine. Considering how mad cow disease was spread (food chain) and
how many farmers will feed their livestock anything cheap to make them fat, I am guessing in the end it will be related to a common food source.
