John is preparing lentils for the meal service. he pours the lentils from the package into the pot and adds water and the spices from the recipe. he cooks them for 30 minutes, but later that night there is a complaint from a patron. what physical contaminant might be in the lentils?

John poured the lentils and without washing them he added water and cooked it as a result John got a complaint from a patron because of that there were leftovers in the lentils (rocks and dirt). Even though John poured the lentils in the pot directly from a bag but the lentils still needs to be washed since they are not hygienic and anyone who eats them may get sick.
