As the numbers get higher, so you pay them more attention. You write plans, and you manage the risk. You manage it out of the equation, you stop doing it, you monitor it, and you reduce the risk. Let me suggest that any score above a six requires your attention. Many months later, you slowly become aware of an issue that could severely affect your brand.
Information is scarce and conflicting.
You can paint your own worst-case scenario. Start paying attention now if you do. You will have noticed the number of recalls related to nuts. Normally, because of the fear of nut allergies, the recalls are initiated because nuts are not declared on the label, or the right product has gone into wrong packaging - just plain carelessness really. But you are all petrified of killing a consumer through your negligence.
