University of Guelph researchers have developed an advanced molecular tool to improve surveillance and detection of Salmonella in poultry. Using a method called CRISPR-SeroSeq, the team can identify multiple Salmonella serotypes in a single sample, offering more accurate monitoring and aiding outbreak investigations. Led by Dr. Shu Chen and Dr. Carlos Leon-Velarde from the Agriculture and Food Laboratory, this research enhances existing food safety measures by addressing the complexity of over 2,600 known Salmonella serotypes.
