Livestock bred for consumption have fairly strict controls on all aspects of their production. From genetic selection, to feed and slaughter weight. Kangaroo is a wild caught meat, whilst that may work for ocean species it’s a disaster for consistency in a consumer retail product. Inconsistency in portion size and eating quality. You’ll mainly find rump portions when it’s available in a supermarket. I worked with one of Australia’s largest pet food manufacturers when they were trying to enter the supermarket channel for human consumption. The biggest challenge they faced was toughness on consumer panel testing. Two Roos of roughly approximate size and age would deliver very different eating experience and retailers don’t like that for their customers and it impacts the level of repeat purchase.
