Shanghai has tightened its grip in fighting food safety crimes, with violators likely to face life bans in the industry.

The Standing Committee of the Shanghai Municipal People's Congress convened to listen to explanation and interpretation of the local measures (draft) on safeguarding food safety.

The deputies also heard a review report of the draft measures to implement the national law on food safety, which urged "the strictest punishment" for violators. The report said that any food companies found operating against the law or caught operating irresponsibly should be barred from the business, while anyone implicated in such illegal businesses should be banned from the food industry for life.

According to the draft measures, local food watchdogs should tighten supervision through a credit system, in which food safety watchdogs will assess food industry producers, businesses and online third-party platforms, record their scores and make the information public.

Authorities should enhance supervision against those with poor credit, according to the law.
