Hi I have a question about Grill Brick ingestion. I opened a new grill brick from its plastic cover next to the grill and table where the bread and buns are cut. Some of the grill brick dust/small particles fell from the plastic on the table and possibly on the grill. If some of the particles from the grill brick got on the food like bread/bun or a burger and someone ingested those particles/grill brick dust would they be ok? From what I read grill brick is not toxic and not harmful is that true. Would it just pass through the digestive system and be excreted? thank you
