BBC Farming Today interviewed Dr Harriet Bartlett about research she led into different types of pig farming, which concludes the current pork labelling schemes do not help to identify the best pig farms for the climate, anti-biotic use, environment and animal welfare overall. "Our results really show that instead of [labelling systems] focusing on the production method or farm type, it would be much better to focus on outcomes that people care about, so actual outcomes for animal welfare and the environment," said Dr Bartlett.
