HONG KONG (AP) -- Hong Kong's food safety agency said Thursday it has found excessive levels of an industrial chemical in a sample of Chinese-made biscuit sticks.
The chemical melamine was detected in EDO Pack Almond Cacao Biscuit Sticks produced by Hong Kong company EDO Trading Co., the Center for Food Safety said in a statement.
The amount of melamine, which is used to make plastics and fertilizers, was 8.5 parts per million in the sample. Hong Kong has set the safe level at 2.5 ppm.
A man surnamed Wong who answered the phone at EDO's office said the company ordered a recall of the product after it was notified about the results.
"Our internal inspection earlier found our products are fine, so we'll have to check again," the man said, declining to give his full name because he was not authorized to speak to reporters.
The biscuit sticks were manufactured by the company's factory in the Chinese coastal city of Qingdao, he added.
The man said the company has used Chinese milk as a raw material in its products but he did not know which brand.
Various Chinese-made milk and dairy products have been found to contain melamine, which is blamed for killing four babies and sickening more than 50,000 in mainland China.
Authorities say Chinese suppliers might have added melamine, which is rich in nitrogen, to watered-down milk to deceive quality tests for protein.
