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.

Compliance Made Easy

Our Granucult® dehydrated culture media are quality controlled and tested in our ISO/IEC 17025:2005 accredited laboratories, with full compliance with EN ISO 11133:2014 and newer ISO standards. All information regarding compliance with additional reference standards are displayed on the product label and in the technical information available on our website. Our new all-in-one Certificate of Analysis provided with each batch of our dehydrated media product additional information besides the microbial performance data that can help in audit situations or lab inspections. Ideal for isolation and enumeration of indicator organisms due to the high reproducibility and low error rate, our ReadyPlate™ agar plates and ReadyTube™ bottles and tubes are quality controlled by ISO/IEC 17025:2005 accredited laboratories, and certified to be fully compliant with EN ISO 11133:2014, as well as with individual standards.

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.

Auxiliary Products

Anaerobic, microaerophilic and capnophilic microorganisms, such as Clostridia or Enterococcus, play a significant role in the food and beverage industries. The Anaerocult® product range includes systems for producing the anaerobic, microaerobic and capneic growth conditions that are required to cultivate these organisms. We have cost-efficient Anaerocult® products for all laboratory sizes.
