Each state has a State Veterinarian who is hired by the state government to oversee animal health matters within the state. The duties of the staff in a State Veterinarian's Office may include monitoring herds and flocks of animals for disease, regulating the movement of animals within and across state lines, animal welfare, and in some states, meat inspection. If you would want to contact someone in your state government regarding animal health and welfare, the State Veterinarian's Office would be a good place to start.
