Translate the following English sentence to French:
"But if we put 'Origin: European Union' , that conceals the fact that the meat may derive from an English cow, riddled from top to bottom with a prion courtesy of their gracious ultraliberal majesties, Adam Smith and David Ricardo."
Mais, si on met "provenance Union européenne", cela cache le fait, éventuel, que la viande provient d'un bovin anglais, infesté, des cornes jusqu'à la queue, du prion de leurs gracieuses majestés ultralibérales Adam Smith et David Ricardo.
