I love how one of the answers is the government "must" be involved. GMO food may harm you. Steroids in food may harm you. Factory farming is a terrible farming practice, and yet, it is against the law to film it. These are a few issues where governments are involved and results are terrible. Can there be issues with street food? Yes! Can there be issues with food in a high-end restaurant? Yes! There are always going to issues with food. If you're a neurotic SOB and are constantly fretting over this and that when it comes to food, you probably will miss out on some excellent cuisine experiences. Just sayin!
