Johnston Mooney & O'Brien have recalled all loaves of bread with a best before date of 11 February 2018 as they may contain small pieces of metal.
The company has said the move is a precautionary measure and that no bun or roll products are affected.
It added that any potentially affected packs have been removed from supermarket shelves in co-operation with retailers and any that were in the distribution system have been recalled.
Anyone in possession of a Johnston Mooney & O'Brien bread product with the best before date 11 February 2018 may return it to where it was bought for a full refund.
Alternatively, they can send the empty packaging with their name and address for a full refund to: Johnston Mooney & O'Brien, 11 Jamestown Road, Finglas, Dublin 11.
The company has apologised for any inconvenience caused by the recall but said it believes it is the most appropriate course of action, however slight the risk might be to consumers.
