Saudi Arabia said on Wednesday that harmful concentrations of melamine had been found in milk powder made by a Nestle plant in China but the world's largest food group rejected the findings.

'All Nestle dairy products sold in Saudi Arabia -- just as anywhere else in the world -- are absolutely safe for consumption. No Nestle product is made from milk adulterated with melamine,' Nestle said in a statement.

Saudi Arabia's Food and Drug Authority reported on its website (www.sfda.gov.sa) that high concentrations of the industrial chemical were found in products sold in the kingdom and warned consumers they could be harmful to health.

Saudi Arabia named the product as a 400-gramme pack of Nesvita Pro Bones and said the batch was produced on May 6, 2008 by a Nestle plant in China. The authority said the product must not be used by consumers of any age.

It said it had also found melamine concentrations harmful to chidren in three other batches of the same brand, in 1,800- and 900-gramme packs made November 19, 2007 and on February 25, 2008.

Nestle said it had organised a withdrawal of Nesvita Pro Bones Low Fat after a request from Saudi Arabia on October 18 to pull milk products made in China, pending results of tests.

Nestle said its tests on the product -- as well as those by an independent laboratory -- gave results well below limits defined by the World Health Organisation (WHO) as well as by authorities in Canada, New Zealand and the European Union.

Nestle made similar comments in October after Taiwan health officials ordered stores there to remove six types of Nestle dairy products after tests found traces of contamination.

Nestle said then its products were safe, adding that Taiwan's standards were 50 times stricter than global norms.

The Saudi agency said it also found melamine in a chocolate wafer cream it identified as 'Apollo' made by Malaysia-based ApolloFood Industries on June, 5, 2008.

The authority said it had tested 52 milk powder products, none intended for consumption by babies. All of the products were made in China or in countries which have found melamine-tainted products, it added.

China has raised to six the number of babies believed killed from drinking a melamine-tainted milk formula, and the number affected to 294,000.

Melamine is an industrial compound found in plastics that has been used to skew government protein content tests.

Chinese media first reported in September that babies had fallen ill after consuming melamine-tained formula, undermining confidence in Chinese-made food products.

The scandal, which is so far believed to have killed six babies and affected 294,000, prompted bans and extra checks on Chinese milk and food products in dozens of export markets.

Last year, melamine was found in China-made pet food ingredients that killed animals in the United States. The United States earlier this month issued an import alert for Chinese-made food products, calling for foods to be stopped at the border unless importers can certify that they are either free of dairy goods or free of melamine. - Reuters
