Leading Chinese dairies are now being investigated in connection with the tainted milk scandal after the banned substance Melamine was found in fresh supplies too.
Four babies have already died in China and thousands are ill in hospital after drinking infant formula laced with the chemical compound.
Now cartons of fresh milk, yoghurts, ice-creams and other milk products are being removed from shop shelves across China and Hong Kong, and further afield in Asia and Africa, even though the Chinese government insists most are safe .
Melamine, if consumed in conjunction with certain other chemicals, can cause kidney stones and renal failure.
It is commonly added to animal feed to make it appear higher in protein content.
Of samples taken from two top dairy producers, 10 per cent of the milk was found to be contaminated.
