NEW ZEALAND: The New Zealand pork industry has been plunged into crisis after secret filming on an intensive pig farm was broadcast on TV this week. PM John Key described the footage, which showed pigs packed tightly together with some chewing on bars, as "very disturbing".

The broadcast led to a protest by animals rights activists outside the office of agriculture minister, David Carter. It also forced trade body New Zealand Pork to defend intensive production, claiming the prohibition of intensive farming would add $2 (77p) a kilo to the retail price of pork.
