The illegal food dye has been shown to cause cancer in mice, but the risk to humans is thought to be extremely low.
The Sudan I dye was in chilli powder used by Premier Foods to make a Worcester sauce then used in other products.
Recall 'costing £100m'
The recall of products is the biggest in British history and has involved soups, sauces, crisps and ready meals. It is estimated to be costing about £100m.
David Statham, FSA director of enforcement, said previously that removing all the affected products from the food chain had been "an enormous undertaking".
Mr Statham said although the risk to health was very small, consumers should not have been exposed to contaminated products.
"We have worked hard to ensure that food companies meet their responsibilities to consumers."
Local authorities will check what actions have been taken.
"We will also work with them in considering what enforcement action may be appropriate following these investigations."
Sudan I is a red dye which is commonly used to colour solvents, oils, waxes, petrol and shoe and floor polishes.
Since July 2003, all dried and crushed or ground chilli coming into the EU must be accompanied by a certificate showing it has been tested and found to be free of Sudan I.
