Test for Quality Indicator Organisms

Quality Indicators

A food scandal or product recall is highly damaging for the food industry, consumers and brand, so prevention is key. It is therefore necessary to continuously improve the test parameters in food production facilities and final products.

One parameter that exemplifies this commitment is quality indicator organisms. These organisms indicate potential hazards to the finished products, which can lead to costly product recall.

The term quality indicator organism can be interpreted in a number of ways. It can be used to describe:

  • An index organism to indicate the presence of pathogens.
  • A measure of hygiene level and proper sanitation practices in production facilities.
  • An indicator of the quality of the product during post production.
  • A marker for fecal contamination.
  • An indicator of the presence of organisms that can lead to spoilage.

Media for Quality Indicator Organism Testing

There are different ways to test for quality indicator and / or index organisms, including traditional methods using our gold standard Granucult® dehydrated media, or our ready-to-use ReadyPlate™ or ReadyTube™ media. In addition, we have a full range of convenient media that can be tailored to your needs.


GranuCult™ low-dust granules are a dehydrated culture media compliant with the new EN ISO 11133:2014 standards as well as other ISO standards and FDA-BAM/USDA-FSIS methods for testing food and water samples.

Rapid and Convenient Microbiological Testing

What if you could use fewer handling steps for your quantitative indicator organism testing, without compromising your results? Streamline your workflow by trying our new color-coded MC-Media Pads for rapid and convenient microbial testing. Compliant with international food and beverage standards (AOAC/Microval) and strain controlled according to EN ISO 11133, this media method can be used for convenient microbiological testing for E. coli, Yeast and Mold, oliform, Staphylococcus aureus, or total aerobic microbial contamination. The clear color coding means that you will always pick the right one at a glance.

For complex matrices, we recommend SimPlate® tests which provide rapid and easy to interpret results, particularly with food and environmental samples that may be challenging for other rapid methods.

Our SimPlate® tests have been validated by international standards (AOAC/MicroVal) and are available for detection of Enterobacteriaceae, coliforms & E. coli, yeast & molds and for total viable counts.
