Our Ultra Klean E-coli and Salmonella test kit was created to address the growing problem of contamination of our nation's food supply. Our easy-to-use test strips are an enzyme detection test with a cut-off level of 7.5 CFU/ml. In as little as 20 minutes you can know whether or not your food has unsafe levels of e-coli or salmonella. The results are easy to read. No color change on the test strip is a negative result, while a color change means a positive result.
