Hong Kong authorities says tests have showed the amount of melamine in Britain's Cadbury chocolate and cookies exceed a safe level for human consumption.

The two contaminated samples announced Sunday are among a list of 11 Chinese-made products being recalled in parts of Asia and the Pacific by the British candy maker.

The center 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 Pacific went unanswered Sunday.

Cadbury has said preliminary tests showed traces of melamine in chocolates produced at its Beijing factory, but the exact level was not known.
