Pitted dates

[snopes]

Comment: I've been looking for urban legends about pitted dates. When I
was in high school in the 60's, a teacher claimed that certain imported
pitted dates might not be pitted under sanitary conditions, since it was
traditional in certain countries to use the teeth to pit dates.

Either this was a short-lived urban legend or sanitary conditions have
improved since then, even in backward theocracies.
