New Zealand recalls dairy products over botulism fears

New Zealand has triggered a global recall of some of its milk products after a contamination scare.

The dairy giant Fonterra says traces of a bacteria that can cause botulism were found in an ingredient used for making milk powder.

China, which imports nearly 90% of its milk powder from New Zealand, has already ordered potentially tainted products off supermarket shelves
