MCC has developed new Quick Tests for the Presence of Salmonella and E. coli O157:H7. They are the same tests that were sold during the early 1990Âs for detecting the presence of those bacteriaÂs and through years of improvement the tests now perform within minutes, allowing for quick detection and segregation of products for confirmation.
The strips will detect the presence of Salmonella or E. coli in a prepared sample with some distilled water added or by swiping across a moist counter top etc. If there is no color development the test is negative and if there is a slightly light blue to a dark blue color change then the test is positive. The tests enable easy visual interpretation of the results within a color development time of 3 to 5 minutes for Salmonella and 10 to 20 minutes for E. coli.
The tests are simple to use and require only a clean plastic cup, a plastic spoon and some distilled water or bottled drinking water (unchlorinated) and a non-absorbent surface to lay the test strip on for development.Salmonella: Response time between 3 and 5 minutes depending on the amount of CFUÂs present, down to several CFUÂs. The color response is a light blue to dark blue color change and its sensitivity was somewhere between 98.9% and 99.9%.E. coli O157:H7: Response time between 10 to 20 minutes depending upon the number of CFUÂs present, down to several CFUÂs. The color response is a light blue to dark blue color change and its sensitivity was between 98.9% and 99.8%.
The strips are easy to use and the response times allow for investigators and inspectors in the field to have a result within a short period of time, before the product reaches the consumer. The use of these strips is unlimited when it comes to checking food supply and surface contamination. They are used with several easy to follow and understand instructions.
This product has been used in past years under the MCC name and has recently been released with improvements to cope with the demand for Quick Tests that are truly rapid within minutes instead of hours.These Quick Tests were developed for use in the field as well as in any environment where one might want to test for the presence of Salmonella or E. coli before product is released, product is processed or product is consumed. Other new tests are being developed in the area of viral and biological contamination of food supplies, food environments, water and other areaÂs where animal or human consumption may take place.
