Cadbury chocolates SA Halal or haram?

Question

Assalam O Alaikum,(Cadbury chocolates SA Halal or haram?). I'm from South africa and recently my father went to Pakistan and as a present he took some cadbury cholocates with him. But later the family members said that cadbury chocolates are declares haram in malaysia and contained dna of PORK. At this point I search internet and found that SANHA is playing with muslims and trying to declare cadbury chocolates halal without testing the products. What is the real story?
