Sewage contains tons of viruses, bacteria, and heavy metals. In developed countries, sewage has to be carefully treated before they can be used again.
In Vietnam, farmers living around Hanoi provide thousands of tons of vegetables for the capital city everyday. Nobody has ever asked how the farmers make their vegetables look 'fresh'.
Everyday, people in Hanoi are still buying this type of vegetables because they are much cheaper than vegetables in supermarkets. Many other, because of their habits, prefer eating the vegetables raw, without knowing that sewage are used to wash the vegetables.
This video is in Vietnamese but it show the story. Don't panic!
