New Zealand dairy companies are taking no chances with melamine, the chemical behind the toxic milk tragedy in China.
They have changed a component in their processing systems found to be the source of low-level contamination from melamine.
The Food Safety Authority started testing dairy products in New Zealand after the scandal broke and found minute traces of melamine in a milk protein, lactoferin, produced by Westland Milk Products.
Another company, Tatua, also found tiny traces in its lactoferin, which is used in some baby formulas, nutriceutical products and health drinks.
In both cases levels were well below the safety threshold set by the authority. Nonetheless, both Tatua and Westland have changed the filters they were using.
Subsequent testing has detected no traces of melamine.
