Discount supermarket chain Aldi has issued a recall for hot dog rolls after metal shavings were detected inside some products.

People who purchased Aldi's six-pack "Bakers Life" hot dog rolls with the "best before" date of July 14 are being urged to not consume the product and return it to the store.

The rolls, packaged in a 450g plastic bag, were sold in Aldi's NSW and ACT stores. The "best before" date can be found on the plastic bag clip.
