YOKOHAMA (Kyodo) Police on Monday raided four companies suspected of reselling moldy rice as edible in 2007.

The raid took place before the Agriculture, Forestry and Fisheries Ministry filed criminal complaints against the four companies later in the day.

As the three-year statute of limitations for prosecution over breaching the food hygiene law will expire in about a month, the Kanagawa Prefectural Police are planning to turn their case against the companies' officials to prosecutors by the end of August.
