[Jurassic Park] What ever happened to that sick triceratops?

During the ill-fated tour run, Dr. Sattler is talking to someone from the park, trying to figure out why the trikes get sick every 6-8 weeks. She thinks it's pharmacological, related to some nearby poisonous berries. She looks through the dino...dino-d-droppings? but can't find any evidence that the trikes have been eating them. It remains a mystery as they get back to the tour, and it's never really resolved due to the ensuing catastrophe. 

So why were the trikes getting sick? Was this covered in the book? I haven't read it in years and I don't have a copy anymore.

Yes, this was covered in the book (though in the book it's the Stegosaurs that are getting sick.) The dinosaurs weren't eating them, they were accidentally consuming them when they swallowed gizzard stones and being poisoned that way. Many animals, apparently including Stegosaurs/Triceratops (depending on the version) regurgitate gizzard stones after they become smooth rather than excreting them-- if Dr. Sattler had investigated dinosaur puke rather than droppings, she would have solved the puzzle.
