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 got a complaint from a patron because he did not wash the lentils and because of that there were remains in the lentils (rocks and dirt). A layer of debris covered it too. Although John poured the lentils in the pot directly from a bag the lentils still need to be washed since they are not clean and anyone who eats them will be vulnerable to bacteria and may get sick due to it.
