Indicator and Pathogen Testing

Food microbiology research is done to test for indicator organisms in addition to pathogens and their toxins. Indicator organisms are specific organisms that can alert the possible presence of pathogens. Let s say, if our food microbiology laboratory detects the presence of Ccoliforms such as E. Coli, there is a possibility of fecal contamination and also the presence of pathogens such as the well-known Shiga toxin-producing strain.

Our microbiological analysis of food products & contact surfaces can test for common concerns as listed below as:
Indicator Microorganisms
  • Acid-resistant microorganisms
  • Fecal contamination indicators
  • Heat-resistant microorganisms
  • Psychotropic microorganisms
  • Spore-forming microorganisms
Pathogens and Toxins
  • Genus Listeria – Listeria monocytogenes
  • Salmonella
  • Legionella
  • Shiga Toxin-producing E. coli (STEC) including O157
  • Vibrio spp.
  • Clostridium perfringens
  • Bacillus cereus
  • Cronobacter spp (Enterobacter sakazakii)
  • Campylobacter
  • Enterotoxins
  • Pseudomonas aeruginosa
  • Shigella spp.
  • Yersinia
  • Staphylococcus aureus

We use testing methods which you can rely upon for detecting and identifying organisms that lead to health risks, food spoilage or other quality issues. To identify indicator organisms and pathogenic strains, we use such techniques which are widely used in the industry such as polymerase chain-reaction (PCR), pulsed-field gel electrophoresis (PFGE), chromatography and enzyme-linked fluorescent assay (ELFA).
