Limits for Melamine in Food Fixed Only Recently: WHO

Many countries have only recently fixed limits for industrial chemical melamine in food products, a World Health Organisation expert said.

This is because the chemical was not considered a substance found in food before a scandal broke out in China where milk products were tainted with the substance, Peter Ben Embarek, WHO food safety expert told AFP late Thursday.

Spokesman for Cadbury Britain Says Melamine Found in Recalled Food
British sweet maker Cadbury found traces of the industrial chemical melamine in Chinese-made products recalled in Hong Kong, Taiwan and Australia, a spokesman for the company said Monday.

"To my knowledge, the EU, Hong Kong and New Zealand have only in recent weeks fixed a transitory limit of 2.5 milligrams per kilogramme for food products, with the limit lowered to 1 milligram per kg for food consumed by children," Embarek said.

He added that "melamine has nothing to do with the food chain and therefore no standard had been fixed on a global level.

"There are billions of chemical products that normally should not be found in food -- it is therefore impossible to fix a limit for all the chemicals. That's the case of melamine," he said.

Chinese President Demands Action as Milk Tests Find Melamine
Chinese authorities said Wednesday that tests had found traces in nearly 12 percent of milk powder products of an industrial chemical that has so far sickened 53,000 children, killing four.

Standards are only fixed for chemicals or elements that are known to be present in food products as they were used during the production process, such as pesticides, explained Embarek.

Melamine, besides internal contamination, could also be found in traces due to accidental contamination through product packaging or through contact with certain surfaces during the manufacturing process.

Milk Sold in Chinese Shops Contains Melamine
Chinese authorities have found melamine in milk sold in stores, state television reported Thursday, widening a scare over contaminated powdered milk in which four people have died.

Some fertilizers, which are rarely used, also contain melamine which could then be the source of traces found in food products, he added.

However, at low levels, the substance posed no health threat.

Milk Farmers in China Blamed in Baby Formula Scare
The Chinese firm whose baby formula is blamed for killing one infant and sickening dozens has accused dairy suppliers of adding a chemical to their milk to up protein content, state media said Friday.

"Melamine has a rather low toxicity -- in traces or in low doses, it is eliminated by the organism without harm," he said.

But with at least four children killed and 53,000 sickened in China by milk products tainted with melamine, governments around the world have moved to test food products containing milk from China.

Authorities, including those in Hong Kong and Taiwan, have banned products that were found to contain melamine.
