Dairy products shortage predicted in China after Fonterra food scare

It takes 20 years to build a reputation and five minutes to ruin it, according to the legendary investor Warren Buffet.

The truism of that claim has been underlined by the recent food scare arising from a dirty pipe at a Fonterra processing plant in New Zealand.

Fonterra, the world’s largest dairy exporter and New Zealand’s biggest company, disclosed earlier this month that whey protein used in milk powder may have been tainted with botulism- causing bacteria.
