Swiss authorities say they have found high concentrations of melamine in biscuits from Thailand and Sri Lanka and have called on other European countries to withdraw the products.
Authorities in the canton (state) of Geneva say tests have shown high melamine levels in the Thai biscuits Milk Cookies S&P and the Sri Lankan candies LemonPuff Munchee.
Melamine in milk has been blamed for the deaths of four infants and for sickening more than 54,000 others in mainland China.
The authorities said in a statement Monday that the European distribution channels for the two biscuits have been identified.
They say tests on a dozen baby milk products have shown no melamine contamination.
