Aside from simple hog improvement, genetics is now being used for DNA traceability. Traceability is important for tracking drug residue, food safety, and marking our pork worldwide as Canadian. The goal of traceability is to trace meat through retail, distribution, processing, slaughter, production, breeding and genetics. DNA tracking could be useful for the slaughter and processing, where tags and tattoos fail to be effective. There is research going on to identify efficient methods of DNA tracing with the goal to make it cost effective and reduce error.

To put this method into practice, replacement gilts will be blood sampled and the sample placed in a bar coded tube. The gilts ID is written next to the bar code and sent to a lab. Although this system is aimed towards quality control and proof of origin, this system can also be used for genetic improvement of the pigs because the carcasses of course will be examined at slaughter.
