In 2010 I saw the documentary ‘Food Inc.’ at BAFTA - a deeply unflattering look inside America’s corporate-controlled food industry and its knock-on effects to the country’s farmers and the health of its citizens. The film showed that the Big Food corporations put their vast profits way above a nation’s health and that this is happening on a global basis.

A year later I met Tracy Worcester who produced the acclaimed and widely broadcast documentary ‘Pig Business’. Now in 21 languages and 7 country-specific versions, it highlights the horrors associated with modern industrial-scale pig production. She continues to make films through her campaign Farms Not Factories, to raise awareness about the rise of factory pig farming, a system which abuses animals, pollutes the environment, threatens human health through dangerous overuse of antibiotics and wrecks rural communities. Her solution is to urge consumers to ‘turn their nose up’ at pig factories and only buy meat from high animal welfare farms.
