It could make your tummy upset, but it's unlikely to cause any issues at all unless the potato is turning green or starting to sprout. It'd taste pretty awful at that point, but I'm not sure I'd trust someone who eats raw potatoes to notice that...

No you can't die from it (save from maybe bacteria if you don't wash it correctly which isn't a potato specific problem that's just produce). The green part of potatoes can make you sick if you eat too much but that's more of a ratio thing and it is present in roughly the same levels cooked or raw.

Imo, the best way to eat them raw is to slice them relatively thin (not so thin as for them to be floppy), sprinkle a little salt on top. They have texture like a water chestnut. Eat as you slice or rinse the slices or else the starches leak and give them a weird mouth feel...

Is it the prison slave labor or is it a whole new fun and exciting reason? Because Idaho spuds are a lot of prison slave labor.
