Sick chicken

In a groundbreaking investigation, Ecostorm and the Guardian went undercover to expose conditions inside the British chicken factories that supply some of the biggest supermarket and fast-food chains in the business, including KFC, Tesco, Aldi, Asda, Marks & Spencer and Nando’s. Undercover footage, photographic evidence and information from whistleblowers revealed how strict industry hygiene standards to prevent the contamination of chicken with the potentially deadly campylobacter bug can be flouted on the factory floor and on farms.

The investigation and film, published in July 2014, sparked a major food scandal, prompting the health secretary to launch an immediate inquiry into the revelations and sparking widespread coverage both in the UK and internationally.
