can you get sick from cow blood? I'm pretty sure you can, and I just drank some coke can that had been covered in cow blood. it leaked out of some burger meat I had in the fridge and dripped into the coke box.
Cow blood is healthier than human blood, actually. There are people who mix it in with their chocolate milk. Just as long as you didn't have 2 liters of it, then you don't have to worry about iron poisoning.
