The physical contaminants that may be in John's lentil are pebbles, dust, sand, pieces of wood, and any kind of dirt that may have joined the lentil during harvesting or processing.

Explanation:

John prepared and cooked the lentils as recommended, any microorganism present in the lentil would have been killed during the proper cooking that John provided the lentils. However, John did not wash the lentils before cooking and this means that any physical contaminant that was with the lentils was cooked with them and caused stomach problems in the people who fed on John's lentils.
