Newly published figures show for first time how US-style factory farms have spread across British countryside
There are more than 1,000 US-style mega-farms in England, Wales and Northern Ireland, including some holding as many as a million animals, according to a new investigation.
In the US, mega-farms are defined as those that hold more than 125,000 birds reared for meat, or 82,000 egg-laying hens, 2,500 pigs, 700 dairy cows or 1,000 beef cattle. These are labelled by US officials as a concentrated animal feedlot system (CAFO).
