The company which supplied halal food found to contain traces of pork DNA has been identified as McColgan Quality Foods Limited, a Northern Ireland-based company.
The company was named as the source of "the very small number of Halal savoury beef pastry products" found to contain pork DNA which it supplied to prisons.
In a statement, food distributor 3663 said:
3663 would like to clarify that the very small number of Halal savoury beef pastry products that have been withdrawn from supply were only ever distributed to custodial establishments.
The products in question are from one particular food manufacturer, McColgan Quality Foods Limited, and have not been distributed to any other customer.
All Halal products from this manufacturer have been withdrawn.
