Unilever has recalled brands of Lipton milk tea powder in Hong Kong and Macau after they were found tainted with melamine.
The company says the chemical was found in four batches of the powder during its internal testing.
The recall is the latest fallout from the toxic milk scandal, which has sickened some 53,000 babies and killed four on mainland China.
Authorities have arrested 27 people in their probe into the scandal, which has spread beyond the initial brands of baby milk powder discovered this month.
