Japan's health watchdog plans to tighten food safety rules and make protecting public health its priority, officials said Friday.

The Ministry of Health, Labor and Welfare will submit a bill to the ordinary Diet session next year to revise the current Food Sanitation Law, after listening to public opinion, they said.

The latest move, which will seek to codify the protection of public health, comes in response to a slew of recent public health fiascoes and scandals.
