In recent years there have been increasing concerns about the potential health risks of genetically modified foods. Consumer perceptions vary between countries, but are probably most pronounced in Europe and least in North America. These have had a profound and controversial effect on the development of markets for GM products. This book presents a compilation of studies of consumer acceptance to GM foods. Theses studies utilized different methods and evidence including: price and expenditure data; experimental methods; "willingness to pay"; consumer attitudes; and economic consequences. Case studies cover a range of countries, including the USA, several European countries, Japan, New Zealand and Colombia. Chapters are based on papers presented at meetings of the International Consortium on Agricultural Biotechnology Research, held in Ravello, Italy.
