A statement from the House of Commons Environment, Food and Rural Affairs Committee said:
The evidence we received from retailers and food processors in the UK and Ireland suggests a complex, highly organised network of companies trading in and mislabelling frozen and processed meat or meat products in a way that fails to meet specifications and that is fraudulent and illegal.
We are concerned at the failure of authorities in both the UK and Ireland to acknowledge the extent of this and to bring prosecutions.
We are dismayed at the slow pace of investigations and would like assurance that prosecutions will be mounted where there is evidence of fraud or other illegal activity.
