Question

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?

Answer 1

Although not many people think this is a must, always rinse and check the lentils for any pebbles or unwanted items if you don't when cooking and serving they may show up and that can be not only gross but a hazard. 

Answer 2

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.

Step-by-step 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.

During harvesting or processing, lentils can be contaminated by physical contaminants such as stones, pieces of wood, dust, clay, sand and any other kind of dirt.
