Dr. Hanner's team at the University of Guelph tested the presence of meats in sausages that were not labelled. The results shows that meat from other species is added in sausages and not mentioned on the label.
This type of fraud can be common and detection can be achieved through DNA identification of different animal species present in sausages. It remains to be seen whether the amounts of DNA correspond to fraud or rather to cross-contamination. Our next research project will focus on this aspect of fraud detection.
