Chinese dumplings containing pesticide have sparked a food scare in Japan.

Ten people, including a mother and her four children, have become ill after eating meat dumplings that authorities believe contained pesticide.

The company that imported the dumplings has issued an immediate nationwide recall for all food produced by the same Chinese factory.

Police say they are investigating the possibility of criminal negligence.

Japan imported around $1 billion worth of food from China last year - this scare will heighten concerns about its safety.
