Consuming or owning exotic animals can propose unexpected and dangerous health risks. A number of animals, wild or domesticated, carry infectious diseases and approximately 75% of wildlife diseases are vector-borne viral zoonotic diseases. [13] Zoonotic diseases are complex infections residing in animals and can be transmitted to humans.
A foreign animal disease (FAD) is an animal disease or pest, whether terrestrial or aquatic, not known to exist in the United States or its territories. [1] When these diseases can significantly affect human health or animal production and when there is significant economic cost for disease control and eradication efforts, they are considered a threat to the United States.

An outbreak of exotic Newcastle disease (END), which resulted in the deaths of 12 million birds in the U.S. in the 1970s, was traced to parrots smuggled from South America."
Cross-species transmission is the most significant cause of disease emergence in humans and other species. [citation needed] Wildlife zoonotic diseases of microbial origin are also the most common group of human emerging diseases, and CST between wildlife and livestock has appreciable economic impacts in agriculture by reducing livestock productivity and imposing export restrictions.

Furthermore, wildlife disease is a disease when one of the hosts includes a wildlife species. In many cases, wildlife hosts can act as a reservoir of diseases that spillover into domestic animals, people and other species. Wildlife diseases spread through both direct contact between two individual animals or indirectly through the environment.
An epizootic disease (or epizooty) may occur in a specific locale (an "outbreak"), more generally (an "epizootic"), or become widespread ("panzootic"). High population density is a major contributing factor to epizootics. The aquaculture industry is sometimes plagued by disease because of the large number of fish confined to a small area.
