麻豆约拍

China and Russia have banned imports of powdered milk and whey products from a New Zealand dairy firm, after it emerged they'd been contaminated with botulism - an extremely dangerous source of food poisoning. Fonterra, the company concerned, is one of the world's leading exporters of dairy products, and has now apologised for the mistake. But it's very bad news for New Zealand, where the economy depends heavily on its multi-billion dollar dairy export industry.

And what's it like to farms in two countries at once? We look at the issues facing farmers whose land straddles the English-Welsh border, now that the two countries have devolved - and different - agricultural systems.
