It's been a common fact in history dating all the way back to the beginning of European colonization: livestock carries diseases. Most of the time they're endemic if you've been exposed to that kind of disease before. However, if we're getting meat from other countries then obviously we haven't been exposed to them. This could create an epidemic that wipes out millions. I am very conscientious when it comes to what I eat. This will simply not stand. People deserve the right to know what they are eating and under what conditions it was grown.
