Real life and other special situations

A trundle round a supermarket, a glance at the kitchen, or a tour of a food processing plant are sufficient to show that there are myriad exemplars of migration into food. They range from the very common, where millions of items are used each day (e.g. metal cans), through occasional or irregular activities (e.g. cooking), to rare events such as repairs. Few — including quite common ones — fit closely the models in chapters 2 and 3, let alone the even simpler models used in regulations. This chapter identifies and briefly considers these situations. As far as possible, topics have been grouped under headings in alphabetical order. No attempt has been made to rate their relative importance.
