Sainsbury's is recalling its own-brand sliced wholemeal bread after some pieces of metal were found inside. The Food Standards Authority (FSA) said: "The presence of metal pieces makes these products unsafe to eat and presents a risk to health."

The recall affects Sainsbury's thick and medium-sliced wholemeal breads, weighing 800g and with the best before date 19 January 2016. No other products are thought to have been affected.

Sainsbury's said "We have been made aware of the possible presence of tiny metal pieces in a small number of the above products. As a precautionary measure, we are asking customers who have purchased this product with the best before date, to return it to their nearest Sainsbury's store, where they will receive a full refund. No other products or date codes are affected by this issue, and we apologise for the inconvenience this may cause."

The FSA advises customers that have already bought the product not to eat them and to return them to the store where they were purchased for a full refund.
