The system first maps the likely regulatory area. A question about date marking, for example, may sit partly in food information law, partly in microbiological expectations, and partly in operational shelf life practice.
It then layers on official guidance or recognised HACCP working structure where the law sets an outcome but not a detailed method. That matters because many food safety tasks are not solved by finding a single article number and stopping there.
Finally, the system depends on the business facts you provide. If the answer turns on whether a product is ready-to-eat, whether there is a kill step, or whether the site exports to more than one market, the quality of the output depends directly on those inputs.
