One time in middle school I was having waffles for breakfast and I dropped the plate onto a tile floor where it shattered into a million pieces. I quickly picked up the waffles and transferred them to another plate to eat after I cleaned up all the shards. Later that day in school I had this super intense intestinal pain that hasn't been equaled before or since, and I spent most of the school day curled in a ball on a bed in the office as it hurt less that way.

There was no vomiting or diarrhea at all which has me thinking I ingested small ceramic shards as the plate shattered into pieces ranging from the size of 1/5th a plate to barely thicker than a hair. Regardless it took me years before seeing or even thinking of waffles didn't make me feel sick.
