Hong Kong authorities say tests have showed the amount of melamine in Cadbury chocolate and cookies exceed a safe level for human consumption.
The two contaminated samples announced today by the Centre for Food Safety are among a list of 11 Chinese-made products being recalled in parts of Asia and the Pacific by the Cadbury.
The centre says samples of the brand's Dairy Milk Cookies Chocolate and Dairy Milk Hazelnut Chocolate Bulk Pack have been found to contain melamine above the city's legal limit.
Calls to Cadbury offices in London and Asia went unanswered today.
Cadbury has said preliminary tests showed traces of melamine in chocolates produced at its Beijing factory, but the exact level was not known.
