A project led by researchers from the Universitat Autònoma de Barcelona (UAB) could offer consumers data about the milk they are drinking.

The ClearFarm Project proposes using electronic monitoring tools dubbed Precision Livestock Farming (PLF) technology connected to QR codes on milk carton packaging so that customers can trace milk to its farm of origin.

According to the researchers, the PLF technology would offer ongoing, real-time monitoring of livestock like cows via wearable sensors. Such sensors would collect data about the animal’s activity and eating patterns, for instance, and ultimately insight into their well-being.

Currently, certification schemes for animal welfare have been informed by single visits to a farm, once or twice a year. As such, that information is limited, according to researchers.

"ClearFarm will be the first platform to provide non-stop, real-time information on animal welfare. Consumers and producers will be able to view information from every single animal on the farm, every single day of the year," the researchers explained.
