Maruha Nichiro Corp. plans to resume operations by September at a plant in Gunma Prefecture, where pesticide-frozen food was found tainted last year, President Shigeru Ito said Thursday.

At a news conference on a final report on the incident at its Agli Foods Corp. plant, Ito said Maruha Nichiro will restart after taking preventive measures such as installing more security cameras.

The report, compiled by a third-party panel, criticized Aqli Foods, one of the firms merged into Maruha Nichiro in April, for lacking awareness and knowledge of food safety and decision-making.

Maruha Nichiro plans to increase security cameras at the Gunma factory to about 170, up from five at the time of the incident, and tighten access to detergents and pesticides.
