If only science was advanced enough to test for such pathogens! Alas here we are trapped in the 1800s. :roll:
Have you never heard of chytrid or rana virus? They were largely unknown pathogens until they lead to massive die-offs in wild populations
<<<Brush-tail rock wallabies are currently being raised in species recovery programs and restored to the wild to bolster populations of this endangered species. Here, researchers found that nearly half of fecal samples from wallabies raised in these programs contained bacterial genes that encode resistance to streptomycin, spectinomycin and trimethoprim. None of these genes were detected in samples from five wild populations of wallabies. The authors add, "How these genes made their way into the wallaby microbes is unknown, but it seems likely that water or feed may have acted as a conduit for bacteria carrying these genes."
Previous research shows that proximity to humans can increase animals' exposure to antibiotic resistance genes and the organisms that carry them. Antibiotic resistant bacteria have been reported in the wild from chimpanzees in Uganda, Atlantic bottlenose dolphins and a wide range of fish, birds and mammals. According to the researchers, their findings highlight the potential for genes and pathogens from human sources to be spread. Power says, "We found that antibiotic resistance genes from human pathogens have been picked up by endangered rock wallabies in a breeding program, and may spread into the wild when the wallabies are released.">>>

Captive-bred wallabies may carry antibiotic resistant bacteria into wild populations
<<<Appropriate health checks should be carried out prior to release. A careful assessment (risk analysis) must be made as to the risks of released animals introducing novel pathogens (disease agents) into the wild population/environment.
These pathogens may have been acquired from domestic animals, other wildlife casualties or humans whilst the animal was in captivity.
The health checks should be designed to minimise the risk that pathogens posing a threat to wild populations of this or other species will be introduced into the environment when the animal is released.>>>
Release of Casualty Dormice (Techniques)
(Pro-tip: The giraffe was found to he perfectly healthy before it was killed and animals are released safely to the wild all the time.)
Pro-tip, research any of the various control protocols used when establishing new wild populations in captivity. One of the main things they try to do is manage the animal in it's home environment as to reduce the risk from geographically foreign diseases and limit it's exposure to animals outside it's immediate environment. Naturally, a zoo, in a foreign country, is the last place such breeding programs ideally take place, especially in open exhibits.
The trolling needs to stop and the topic needs to be discussed civily
