Saudi Arabia's Food and Drug Authority has found a batch of a milk powder made by a Nestle plant in China to be highly contaminated with the industrial chemical melamine, the authority said on Wednesday.

"(The) Product contains high concentrations harmful to health ...," said the authority in a statement posted on its website (www.sfda.gov.sa).

A spokesman for Swiss-based Nestle was not immediately available for comment.

It named the product as the 400-gramme Nesvita pro-Bones and said the indicated batch was produced on May 6, 2008 by a Nestle plant in China.

The authority said the product must not be consumed by consumers of any age.

The authority said it had also found melamine concentrations that are harmful to chidren in three other batches of the same brand, but of different weights.

The agency also found melamine in a chocolate wafer cream it identified as 'Apollo' made by Malaysia-based ApolloFood Industries, according to the web site.

The authority said the four products must not be consumed by children. - Reuters
