Objective

For food microbial inspection, faster results allow products to be shipped faster, especially for qualitative test, like coliforms, in case of a positive result. To act immediately with irregular results, it is important to get information faster.


Desoxycholate medium (DO) which used for coliforms detection requires at least 18 hours. On the other hand, Rapid-media (RM-DO) requires only 12 hours to get the results, and this has been reported before. Adding to this report, we report the possibility of further rapid detection of Escherichia coli with real-time & automatic colony counting system (ScanStation by INTERSCIENCE made in France) which allows incubate and colony-counting at the same time during 24 hours-incubation.

Conclusion

Use of Rapid Media-DO

Rapid detection of coliforms can be realized from 12 hours-incubation at the earliest

Use of ScanStation

ScanStation vrbl

Owing to 24 h-monitoring and continuous image analysis,
ScanStation counts only colonies for which sufficient growth is found from successive images.


It makes possible to get accurate information of colony-detection at early stage.
With ScanStation, it requires appx. 8 hours at earliest to detect first small colony hard to see by human eyes.

Combination of Rapid Media-DO and ScanStation proves that we can take quick actions when we find abnormal results (appx. 8 hours at the earliest).
