Fingerprinting microbes to solve food contamination mysteries

  • Researchers in Norway have developed a new technique able to trace microbial food contaminants within the production chain. The technique uses Fourier Transform Infrared (FTIR) spectroscopy to ‘fingerprint’ the unique spectral image of over 200 food microbes. Scientists analyse samples throughout the food production process to identify and locate the source of contaminants.
  • The method can be used by non- experts and is quicker and more economical than conventional microbial identification techniques.

Though numerous contamination identification techniques are available, given the high profile of food safety it is important that government consider all technological advances to improve monitoring and detection.
