A national food distributor is recalling chilled dog food that may be contaminated by metal fragments.

In newspaper advertisements today Auckland-based Mars New Zealand said it was recalling its Pedigree and Optimum brand "dog roll products" as a precaution to protect the health of dogs.

The voluntary recall relates to Pedigree brand beef and liver, lamb and vegetable, beef rice and vegetable, and chicken and rice dog rolls; and Optimum beef, lamb and vegetable, chicken and rice, and selected meats rolls.

All have "best before" dates between October 16 and 19.

The products were sold at grocery and pet food retail outlets through the county.

Consumers are urged not to feed the rolls to their dogs and to return them to the place of purchase for a full refund.
