A scientific study of 100 “single species” sausage, such as beef, pork, chicken, turkey and others, was conducted in Canada. It found that 14% of sausages were mislabeled as single species but contained additional undeclared species. There is some encouraging news, however: While this is still an issue that requires monitoring, 14% mislabeling is a lower rate than detected in a previous study conducted a year ago. The samples were tested at the molecular level with DNA Barcoding and ddPCR (Droplet Digital Polymerase Chain Reaction) to detect the species via their DNA.
