The FSA is meeting retailers and suppliers today, David Cameron's spokesman has confirmed, and the first "meaningful" results of a programme of product tests by retailers and suppliers should be available by Friday and will be made public.
Those tests may point to the possibility of fraudulent behaviour, the spokesman said. But he played down the chances of an import ban on meat products given that EU law only permits such a move in the case of a risk to public health. He added:
When it comes to questions of food safety, the right thing to do is to go on the expert advice, and we have had that from the FSA and the Chief Medical Officer.
The spokesman said "the primary responsibility is with the retailers and suppliers" in the horsemeat contamination scandal, plus a "responsibility on those purchasing to check with their retailers and suppliers about the steps they have been taking to ensure the correct labelling".
