There is a black market for illegal cheese according to the Department of Homeland Security.
Which, I know my next D&D character. A dastardly, and devilishly handsome rogue, who's a connoisseur of fine and exotic cheeses, some of them deemed illegal and unsafe for consumption via the kingdom he lives in, and he makes his living by smuggling illegal and exotic cheeses to his clients. All kept confidential of course.
His business front is selling and making legal cheeses, some of which are considered almost addictive thanks to his love of goats and cows.
