TIL that in 2020, Burger King ran an advertising campaign featuring a picture of a moldy Whopper, to prove that their burgers are made without preservatives. This unconventional advertising method worked, increasing sales by 14% (according to multiple sources.)
I mean, there’s arguments where that’s a good thing. Depends on who’s doing the eating, and who’s wanting the ingredients to change.
Me? I’m of the mind that the problem would be one of false advertising, as they have often used beef as a term, and in most places with English as a frequent or dominant language, beef means cow meat.
When it comes down to it, meat is meat. Kangaroo has benefits and drawbacks to its husbandry, resource usage to get to market, and in cooking. Beef has all those points that vary, as do any livestock.
