The traces were found during a periodic check for non-halal ingredients in food products by the Ministry of Health, which on Saturday said two of three samples of the company's products contained pork traces, the website said.

The two products, Cadbury Dairy Milk Hazelnut and Cadbury Dairy Milk Roast Almond, were readily available in stores throughout the country, Nikkei said.

Cadbury Malaysia, like most food makers in the country where Muslims make up more than 60 percent of the population, has all of its products certified halal to conform with Islam's dietary restrictions, one of which is a prohibition on pork.

The company said it was undertaking a full review of its supply chain to ensure halal standards, according to the report, and the Malaysian government said it will conduct inspection of all Cadbury Malaysia's products.

Cadbury Malaysia was not immediately available to comment on the Nikkei report.
