The acclaimed science writer uses chicken as the lens for examining everything that has gone wrong in the modern agricultural system: overuse of antibiotics, threats to the environment, violations of animal welfare, destruction of farm economies and rural civic structure, disruption of international trade and delivery of over-processed, obesity-promoting, nutritionally hollow food. McKenna takes us from vast poultry farms to laboratories, kitchens and street-food markets around the world, revealing how economic, political and cultural forces converged to make our favourite meat a hidden danger. Boycott is chair of the London Food Board.
