Displayed in areas where breeding programs grew out of control, perhaps species in captivity broke out. These areas are totally reclaimed by nature and the ecosystem is incredibly delicate due to over/under population.
People are warned for nature's sake, diseases or other illnesses carried by people could cause devastating damage. Or there are new strains of diseases in these areas that are immune to vaccinations, superbacteria.
This could also apply to flora, not just fauna. Perhaps a fungus has run wild?
