The first time I learned of these was from the movie "The Naked Prey" where the according to google search,

  • He [protagonist] finds a giant African land snail (Lissachatina fulica) crawling on a rock.
  • Starving and exhausted, he uses his knife to carve the large mollusk out of its shell and eats the snail meat raw.
  • After swallowing it, he comically picks a sharp thorn off a nearby bush to clean his teeth.
