This past week, responsible adults have been popping Switch game cartridges in their mouths and finding that the flavor is... disgusting. While electronics and other non-edible products like plastics generally don't have a desirable flavor, it appears that Nintendo has actually taken it a step further by "seasoning" their Switch games.
According to the folks at Kotaku, Nintendo has officially responded on why Switch cartridges have a foul taste and it appears that there is a non-toxic coating that's applied to the exterior in order to prevent accidental ingestion.
“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.”
As explored earlier in the week, Switch game cartridges are some of the smallest produced and it would make sense for Nintendo to add safeguards, albeit this is a pretty unusual but effective one.
For those interest, the Nintendo Switch is now available for purchase from various retailers, but it might be a bit difficult to find through official sources. The console retails for $299.99.
