Roos can and do carry alot of different parasites ,i ate roo meat for 3 months once [something i dont want to do again],but made sure they were healthy and younger animals .Kangeroos need worms in their gut to digest their food without them they die ,my brother who works for the DPI ,told me about pet kangeroos dying, after being drenched for worms because they ''clogged up''[apparently humans and dogs dont get these worms.The worst is Hydatids which mainly appear on lungs heart liver and is nightmarish to look at, and worse if a human gets it ,i have only seen two animals with it ,and that was the last five years[ i think because of changes in the weather ] .Other, are worms in joints, big clumps of them ,worms in the meat itself ,tapeworms in the liver etc .Or another one, is a purple colour to the lungs heart and a ''off ''smell .If in doubt DONT !!!!! Roos in certain areas seem to have certain parasites ,different properties i shot on ,would have their own parasites ,where as others only 10 or 15 ks away would not .
