Denmark develops pig traceability without tattoos

A Danish research institute developed a method that guarantees pig traceability without the need to tattoo.

The new method could save pig producers much effort in the future and remove the discomfort for pigs, according to the Danish Meat Association.

Before pigs are sent to slaughter, they normally receive a stamp with a number in order that they can be traced for product safety reasons.

The so-called 'group method' of tracing has been developed by Danish researchers to allow dispatch of pigs to the slaughterhouse in groups. Upon arrival at the slaughterhouse, the truck driver enters the freight delivery details into a computer terminal. The origin of the group is immediately noted by an electronic data system. Only the door of one pen is opened at a time where the animals are then kept in groups of 15.

The pigs are sent to slaughter in groups of 7 or 8. This procedure is electronically monitored. A scanner checks each belt to ensure that it is empty before dispatching the next group of pigs to slaughter. Finally, chips in the chains where the animals are hung ensure traceability of pork.

Danish Crown has used such a system for two years now, but the Danish Meat Research said it still needs fine-tuning.

Currently, tattooed pigs have been used. As soon as veterinary authorities approve the system, the tattoo will no longer be necessary.
