SYDNEY - A third product was withdrawn from sale in Australia Wednesday due to fears it may contain a contaminated milk product from China which has killed four children and sickened 53,000.

Food Standards Australia New Zealand (FSANZ) has already called for White Rabbit sweets and Chinese-made Cadbury chocolate eclairs to be voluntarily recalled over fears they may contain the chemical melamine, used in the manufacture of plastics.

"Australian importers of Lotte Koala Biscuits have also undertaken a precautionary withdrawal," it said in a statement.

"This follows overseas reports of contaminated ingredients. Consumers are advised to not consume the product. Consumers should dispose of the product safely out of the reach of children and pets."

FSANZ said authorities were testing a targeted range of products from China containing dairy items as a minor ingredient but so far only White Rabbit milk-based sweets had shown positive test results for melamine. - AFP/vm
