The farm situation is well documented. The mistake that Spain made was in not placing any real controls on how they worked, meaning that the usual slave labour that Spanish farms rely on were yet again housed in cramped and unsanitary conditions. It was a perfect place for such a mutation to take place, and it seems that it was really responsible for a significant amount of damage.
