Contaminated dairy products in China

An investigation is underway in China following reports of melamine-contamination of several brands of dairy products. The Ministry of Health of China has confirmed that as a result of this contamination, thousands of infants have developed kidney stones, a condition that is usually rare in infants [1]. Some children have died. Contaminated products manufactured in China have also been detected in Singapore and Hong Kong [2].

Melamine contamination was first detected in powered infant formula. However, following tests conducted by Chinese authorities, several dairy products from at least 22 manufacturers across China have been found to contain melamine at varying levels. An extensive recall of contaminated products has been implemented.

Advice for travellers

Melamine is an industrial chemical used in the manufacture of laminates, glues, and adhesives. Melamine is not an approved food additive, but is known to falsely boost the measurable level of protein when added to food products. The toxic dose of melamine is lower in children than in adults.

Travellers should avoid ingesting dairy products until all contaminated products have been identified and recalled. Mothers with breastfed infant children are advised to continue breastfeeding.

The Hong Kong Centre for Food Safety (CFS) has tested infant formula and other milk products manufactured in mainland China. A list of products that tested positive for melamine is available on the CFS website. There is currently no evidence that any of the affected products have been imported into the United Kingdom [3].

A series of frequently asked questions is also available, in English, on the CFS website.

Two national help lines, one in Beijing and one in Shanghai, have been set up which are available 24 hours a day:

• Beijing: 010 12320
• Shanghai: 021 12320
