Nissin Food Products, Co., which makes the Cup Noodle brand instant noodles, said it was recalling the products and advised customers not to eat noodles that had an odd smell or damaged packaging. The recall only applies to the Cup Noodle brand instant noodles in Japan.

The recall covers 500,000 cups of instant noodles, according to Japanese media reports.

It is the latest case of tainted food to strike Asia in recent months. The industrial chemical melamine was found in a host of Chinese-made milk products in September, prompting a string of recalls in dozens of countries.
