Anthony Hazzard, regional adviser in Food Safety of WHO, said the United Nations health watchdog has already advised the 167 member-countries of the International Food Safety Authority Network to be on guard for the possible entry of 22 Chinese milk products found to be contaminated with melamine.
The WHO warning came as concerns for the tainted Chinese milk triggers a global ban on China's dairy products to include candies, yogurt, chocolates, rice balls, and ice creams.
British supermarket chain Tesco has ordered the removal from its shelves of Chinese White Rabbit Creamy Candies.
France has also ordered a stop to the importation of Chinese-made biscuits, candy or other foods that could contain Chinese dairy derivatives.
On Wednesday, South Korea followed the earlier decision of several Asian countries to ban the imports of Chinese food products containing milk.
Hazzard said, "Countries near China have people who are crossing the border all the time so the potential is there for illegal export of the melamine-contaminated products. Right now, we have no indications that there are illegal exports of contaminated milk products in the Philippines."
However, WHO is not calling for a total ban of milk products from China but said government must take necessary precautions to prevent the spread or entry of contaminated milk into their ports.
