SINGAPORE: banned all dairy imports from China on Friday and the European Union demanded answers from Beijing as the baby formula scandal that has left thousands of infants ill across China spread to liquid milk. A government food quality watchdog in China said nearly 10% of milk and drinking yoghurt samples from three major dairy companies were contaminated with potentially deadly melamine. At the latest count, 6,244 children have become ill. Four have died and 158 are suffering "acute kidney failure".
