The game cartridges for the Nintendo Switch taste terrible. “Of course they don’t taste good,” you say. “They’re not meant to be eaten.” It’s more than the normal plastic flavor. There is an acrid bitterness to the little cartridges that was first reported by Jeff Gerstmann of Giant Bomb when he jokingly put one in his mouth. Soon after, other people were trying the cartridge taste test and reporting similarly bitter results. Is it purposeful? Does the awful flavor have a reason? Nintendo has confirmed with Kotaku that they did indeed manufacture the cartridges to have a repulsive flavor.
“To avoid the possibility of accidental ingestion, keep the game card away from young children. A bittering agent (Denatonium Benzoate) has also been applied to the game card. This bittering agent is non-toxic.”
Denatonium benzoate is the most bitter compound known to humanity. If you say Nintendo Switch games make you gag, you won’t be exaggerating.
