Eating food along the street is dangerous

Now that many pollutants are everywhere, eating street food is dangerous. Even in many progressive countries, street vendors are selling newly-cooked food that lure the palate or taste buds of bystanders. I didn't have any grudge with the vendors but authorities should issue health warnings and certificate to ensure people of the safeness of the food they are selling. Even we're selling food at home, we must ensure the safety of the ingredients we are using.Food Poisoning can cause fatal effects or even death to people who are at risk when eating street food. Street vendors serve their food hot but are we sure it's safe?
