> Isolating animal species, specifically separating their waste, prevents cross-contamination.

Not even close to true. The act of isolating (concentrating) animal species, pumping them full of antibiotics, and concentrating their waste is a significant danger to human and animal health alike. It breeds antibiotic resistant strains of disease and the waste is never isolated - it always gets into the soil, air, and groundwater of the surrounding communities increasing the risk of cross-contamination downstream. These are well-documented, peer-reviewed, large scale impacts that you somehow ignored when googling for n=1 anecdotes to confirm your bias.
