Hazard Types and Definitions According to Sainsbury and Vaughan-Higgins (2012) and Masters and Sainsbury (2011).

Hazard type	Definition
Source hazard	The infectious agents or strains of these agents, carried by translocated individuals which are novel (alien) to the release environment (Sainsbury and Vaughan-Higgins 2012)
Destination hazard	The infectious agents found at the release environment to which the translocated animals are naïve (Sainsbury and Vaughan-Higgins 2012)
Carrier hazard	Those commensal organisms that cause disease when stressors reduce host immunocompetence and alter the host–parasite relationship (Sainsbury and Vaughan-Higgins 2012)
Transport hazard	Those hazards that may be encountered during the transport (between the source and destination) which are novel to the translocated animals and/or the release environment (Sainsbury and Vaughan-Higgins 2012)
Population hazard	Those non-infectious and infectious agents present at the release site that could potentially have a negative impact on a population as a whole but which are not necessarily novel to them (Sainsbury and Vaughan-Higgins 2012)
Zoonotic hazard	The infectious agents carried by the translocated species which can be transmitted to humans and potentially harm the latter (Masters and Sainsbury 2011)
