3.1.5 Many of the dangers to our health resulting from the food we eat arise from the way it is produced, that is, the modern intensive farming practices involved. Thus a national food safety agency that fails to address the question of food production will be unlikely to protect us effectively from damaging our health through the food we eat. So we need a much broader approach to the issue than the traditional British approach where local health officials only intervene at the level of food retailing, for instance inspecting premises where food is prepared or sold.
