HONG KONG , China ( CNN ) -- Unilever is recalling four batches of Lipton Milk Tea sold in Hong Kong and Macau after finding traces of the chemical melamine in the product , the company said Tuesday . Unilever Hong Kong Limited described it as a precautionary measure and said no other Lipton Milk Tea Powder products were affected . The announcement came a day after British confectioner Cadbury said it has recalled all of its Chinese-made candy products after preliminary tests showed they contained trace amounts of melamine . Some of the products were exported to Taiwan , Hong Kong , Australia , Nauru and Christmas Island , according to the company . They are the latest companies to get caught up in China 's tainted milk scandal , which began earlier this month when authorities discovered melamine in powdered infant formula . Watch how scare affects companies outside China » . Contaminated milk has sickened nearly 53,000 children in China , killing four . Countries around the world have since banned the import of Chinese products containing milk , or have withdrawn products that contain milk from China -- such as chocolates -- amid worries they contain melamine . Authorities have arrested 40 people in connection with the milk scandal , including two brothers who could face the death penalty if convicted . Investigators suspect people watered down milk in an attempt to sell more of it , and added melamine in order to fool quality checks , Chinese authorities have said . The toxic chemical is used to bolster apparent protein levels in diluted or poor-quality milk . Others arrested include 19 managers of pastures , breeding farms and milk-purchasing stations . Chinese authorities have said those arrested were involved in a network that made and sold melamine . Authorities have implicated 22 Chinese dairy companies in the scandal . Melamine is the same industrial contaminant from China that poisoned and killed thousands of U.S. dogs and cats last year . Health experts say ingesting melamine can lead to kidney stones , urinary tract ulcers , and eye and skin irritation . It also robs infants of much-needed nutrition . The U.S. Food and Drug Administration has said a company in Taiwan , the King Car Food Industrial Company , had recalled seven instant coffee and milk tea products that were sold in the United States under the Mr. Brown brand name . They contain a non-dairy creamer found to be contaminated with melamine . The FDA also recommends that U.S. consumers not eat White Rabbit Creamy Candy , which in China has been found to contain unacceptable levels of melamine . The candy 's maker , Guanshengyuan , has recalled its exports of White Rabbit Cream Candy .
