Two samples of Cadbury chocolate that are said to have traces of pig (porcine) DNA have been taken from a factory in Bangi for tests, said Minister in the Prime Minister's Department Jamil Khir Baharom.

He said the samples were being examined by a laboratory in Petaling Jaya authorised by the Islamic Development Department (Jakim) to issue halal certificates.

The lab, gazetted as a competent food laboratory in food analysis, is accredited by the Department of Standards under the Laboratory Accreditation Scheme of Malaysia based on the Standard of MS ISO/IEC 17025: 2005 for DNA testing, including testing of processed foods.
