You cant actually trust that its safe to eat, you just like the idea and act accordingly. And deal with the consequences of the uncaught error cases. Tainted food still occurs. At best you can be confident / trust that a product is created in a given process which manages certain risks through certain means. Also, finding faults in said process is a lot easier then coming up with it or executing it. Be it making a sausage that is unlikely to make you sick or coming to an expert judgement with sufficient confidence to act on. It doesnt require the ability to validate a process to find it faulty, you just have to detect an error case occurring that isnt dealt with.
