The Ministry of Justice is to suspend a firm supplying meat to prisons after tests found that it may have provided pies and pasties described as Halal - but with traces of pork DNA.
The Food Standards Agency (FSA) said the "local authority" involved was investigating, while the MoJ said the products have been withdrawn.
Justice minister Jeremy Wright said the incident was "absolutely unacceptable".
Under Islamic law, Muslims are strictly forbidden to eat pork.
