Does anyone know for sure?

I never heard any of that mumbo-jumbo, but...
Whoever said that Grandma warned that raw potatoes can give you
worms...
had a smart Grandma! Potatoes, if grown in infected soil, can
themselves be infected by trichina worms. I'm surprised that none of
you so far has remembered any of this from your high-school biology
classes.
Anyway, the trichina is a parasite which will lie dormant in a
potato, waiting for some unsuspecting slob to eat it. Then, the
trichina will "wake up" (forgive the non-technical explanation), and
infect the host. The parasite causes painful inflammations, and can
imbed itself into muscle tissue, where it can lie dormant for long
periods. The condition is treatable.
The feces of infected pigs can carry trichina "sleepers" or whatever,
and if these feces are used as fertilizer on potatoes, the spuds can
themselves carry the worms. The worms are not microscopic, but a bit
bigger. However, you can't see them in infected potatoes or pork
meat, unless you have very good eyes, and are lucky enough to look
exactly where the worm has embedded itself.
Trichina used to be more prevalent, mostly found in pork meat, but
also in potatoes. That's why Grandma advises cooking potatoes and
pork well, to kill any possible trichina. These days, trichina is
almost unheard of in civilized countries, but remains a problem where
unsanitary farming conditions continue. I remember hearing that they
have had an average of fewer than 1 reported case of trichina per year
in the USA for the past 10 years. (It could be much less than that,
like only 1 case total in the past 10 years; sorry, I can't remember
the details).
So, anyway: eat your raw potatoes.
