The public is not at a direct risk from any zoonotic diseases which are communicable among animals, particularly swine and humans. Farm workers, veterinarians, and slaughterhouse employees may, however, be suspectible to exposure throughout their daily activities.

It is in the best interest of producers to maintain healthy animals and a safe working environment. See
