Another interesting fact about switch game cards is that they taste horribly. You can see several videos online of people tasting them. Theory was that it was coated in something to avoid kids from swallowing the small cards. But I'm not sure this was confirmed by Nintendo.
βTo 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.β
It's good that news travels fast today, or else people who didn't wash their hands after handling carts could be in for a surprise when they ate. That's the same chemical used in air dusters to stop them being inhaled deliberately.
