Number one on the forbidden list? Don't pick your nose. Also banned are cleaning one's ears, smoking while handling food and spitting into the wash basin or sink.
The goal of the program is to create "safe zones" in popular areas, but is it really possible to sanitize street food in India, where suspending any fastidious concern for hygiene has always been part of the deal?
Many Indians already have ways of finding the freshest and most succulent chaat, the small plates of savory snacks sold on the streets.
Dharm Singh, an 18-year-old high school student in New Delhi, said he only goes to places recommended by others and where there are no flies on the food.
He also pays special attention to where the vendors wash their utensils. He learned that lesson the hard way, through a brutal stomach infection he contracted by eating chole bhature, a dish of spicy chickpeas, from a vendor who used dirty dishes.
"He washes his utensils right next to the sewer," said Singh, who was tucking into a plate of lentils, cucumbers and warm bread known as roti on a recent afternoon. "I was sick for a week."
