HONG KONG - Anglo-Dutch company Unilever says it is recalling some of its Lipton-brand milk tea powder in Hong Kong and Macau after they were found to contain traces of an industrial chemical.

Unilever Hong Kong Ltd. says in a statement issued Tuesday that internal test results have found four batches of Lipton milk tea powder contaminated with melamine.

The company says it is recalling the products as precautionary measures. Hong Kong authorities did not find melamine in Lipton products so far.

The statement did not say whether the tainted products were manufactured in mainland China, but they are distributed in Hong Kong and Macau.

Last week, Unilever has removed Lipton Green Milk Tea from the Taiwan market because the product uses Chinese-made milk.
