Describe what DNA fingerprinting is and how it is used in food safety

What will be an ideal response?


DNA fingerprinting is a technique in which bacterial DNA "gene patterns" ("fingerprints") are identified and stored in electronic databases. These patterns enable researchers to distinguish among the various strains of a bacterial pathogen. In food safety, DNA fingerprinting enables public health workers to ascertain whether the bacterial strain causing a foodborne illness in humans is the same as the strain identified in a food suspected of causing illness. Finding the same strain in a food and in ill individuals provides information on the source of the illness and enables public health personnel to track the course of the illness.
