Safety in the cockling industry was set to be discussed at a meeting involving government officials in Lancashire.
Mrs Smith says the government must act to improve cockler safety
Geraldine Smith, MP for Morecambe and Lunesdale, set up the meeting following the deaths of 21 cocklers in February.
The gathering on Monday was also prompted after 130 cocklers were rescued when two tractors collided in Morecambe Bay.
Mrs Smith has warned another tragedy is "waiting to happen" and is calling for tougher regulation of the industry.
The collision, on 7 August, took place four miles offshore, close to Hest Bank, where the Chinese cockle pickers died in February after becoming stranded by the tide.
Members of the fisheries section of the Department for Food and Rural Affairs (Defra) are taking part in the meeting at Morecambe Town Hall.
Following the recent rescue, Mrs Smith said: "There is a tragedy waiting to happen in that bay.
"I have tried to make it crystal clear that if further action is not taken, someone will
"It is really up to the government to do something about the situation."
She said there was a particular problem with Chinese illegal workers at Morecambe Bay, and called for temporary work permits for them and a proper licensing system.
She has also criticised the Heath and Safety Executive (HSE) for a "complacent" attitude to the issue of safety in the bay.
However, the HSE said it had been working with Defra and the Department for Work and Pensions on safety and licensing issues.
