Currently, there are several groups of animals for which there are special conditions regarding their importation due to zoonotic disease potential: turtles and turtle eggs cannot be imported for commercial purposes, and turtle imports as personal pets and for research require an import permit; raccoons, foxes, and skunks require a rabies certificate and a quarantine period; psittacine birds can only be commercially imported from the United States and certain other approved countries under an import permit and quarantine.
