Test interpretations

We provide food and feed manufacturing companies with recommendations regarding appropriate microbiological test and interpretation of test and re-test results for pathogens.

Indicator Organisms: The meaning of indicator organism test results are frequently confusing and often misinterpreted. Kornacki Microbiology Solutions interpret the test results relative to each particular instance, situation or food. Reference article: Kornacki, J.L. and J.L. Johnson. 2001. Enterobacteriaceae, Coliforms and Escherichia coli as Quality and Safety Indicators. Chapter 8, In R.S. Flowers, et al. (eds.), Compendium of Methods for the Microbiological Examination of Foods, 4th ed. APHA, Washington D.C.

Pathogens: The results of pathogen testing are frequently challenged. These challenges fall into several categories:

Laboratory cross contamination. See Consulting Services>GLP
Contamination during sampling.
Disparities in retest results.
Actual product contamination.

Kornacki Microbiology Soluions, LLC can assist you in determining the true source of your positive pathogen results.

Spoilage Organisms: Undesirable food product defects; gasiness, off flavors, excessive acidity, color etc, can result from food contamination with spoilage organisms. The levels of these organisms may be of no effect, great effect or potential future effect depending upon extrinsic and intrinsic factors. We can help you interpret the meaning of spoilage organisms test results on a case by case basis and or recommend additional tests or actions.
