“…There is a strong economic incentive for private management of animal diseases with obvious symptoms, high mortality and morbidity, and apparent costs outside management costs (Roberts, 2006); while animal diseases with no obvious symptoms and no major impact on private production decisions have weak incentives for private management. Private management of diseases with no obvious symptoms can be accomplished if contracts, regulation and laws mandate their control (Ranjan and Lubowski, 2005; Roberts, 2006). Other incentives for private control include: animal death and productivity losses, indemnity payments, payments for reporting sick animals, private insurance requirements, mandatory testing on farms before slaughter, possible destruction of positive or diseased animals if found after testing, business interruption and loss of opportunity, and quarantine of farms having the disease of concern.…”
