Food is business. Those who produce and sell it – seed companies, farmers, shops and restaurants – are inevitably major players in the GM debate, with those whose profits are the biggest tending to have the most to say. In this chapter we look at the pronouncements of supermarkets and biotech seed companies. Their voices, and their attitudes to GM food, are rather different. For while the biotech companies are almost by definition pro-GM, the supermarkets are more exible, prepared to be blown, pollen-like, in whatever direction the winds may take them.
