OSAKA -- Police in Hyogo, Ehime and Tokushima prefectures plan to search three sales offices of Nippon Food Inc. and related locations next week in connection with their investigation into a beef-mislabeling scam, police sources said Thursday.

Nippon Food is a subsidiary of Nippon Meat Packers Inc., which is better known as Nippon Ham.

The searches next week will cover Nippon Food offices in western Japan and mark the third searches carried out in connection with the mislabeling case since the investigations into the now-defunct Snow Brand Food Co. and Nippon Shokuhin Co., the sources said.
