Surely they worm the farmed roos.
Says here 'newly' identified... I've seen these worms going back to when I was a kid, they're not new worms, but perhaps newly identified, or a different species.

A newly identified worm thought to be derived from marsupials was found to be responsible for acute illness in two humans. Like Trichinella they invade muscles. The worms are thought to belong to a class of nematodes known as Muscpiceoids. In wallabies and possums these nematodes live in several tissues of the body and can invade muscles.
In his paper to the University of Tasmania (1997 114 ), Professor John Goldsmid said, "Kliks (1983) identified the aetiological agents of human infectious diseases as "heirloom" or "souvenir" species, depending on their evolutionary association with humans. Amongst the most important of the souvenir species are the zoonotic infections, infecting humans as a result of animal-human contact of some kind and varying from companionable contact to utilisation of animals as a food source.
In the last 25 or so years, of 35 new or newly recognised infections in humans, 20 (57%) have been zoonotic in origin - some trivial, some devastating to both the individual and the community.
With the increase in the numbers of immunocompromised people in the community resulting from medical treatment or as a result of the spread of AIDS, the problem of zoonotic infections will continue and there seems little doubt that the likely source for many of these new human infections in Australia will be the native animal population.
People who eat undercooked wallaby or kangaroo meat could be at risk of infection by a newly-discovered animal parasite, Australian doctors have warned.
The parasite was found in a Tasmanian man who suffered from inexplicable and severe muscle weakness over a number of years. He was known to consume large quantities of game. ("Parasite Risk to Game Eaters" November 7, 1997 Animal Pharmacology No. 384)
Laboratory tests suggests that the parasite is a new species of microscopic worm. It may also have been responsible for a similar infection in a New Zealand woman who had eaten wallaby meat while visiting Tasmania.
