molecular typing
A way of identifying specific strains of organisms by looking at their genetic material. Often used to characterise bacteria or viruses
In food safety, molecular typing is a set of laboratory methods used to identify and compare the genetic makeup of microorganisms, like bacteria, to see how they are related. This helps scientists track where bacteria come from and how they spread.
EFSA uses molecular typing to investigate foodborne outbreaks, monitor pathogens like Salmonella or E. coli, and study antimicrobial resistance. By comparing the DNA of bacterial strains from food, animals, or humans, EFSA can link cases, trace contamination sources, and provide accurate risk assessments. Molecular typing is also used in GMO risk assessment to identify and characterize inserted genes, verify genetic stability, and check for unintended changes or interactions. EFSA relies on these analyses to ensure GMOs are safe for human and animal consumption and to assess potential environmental impacts.
