Every year, approximately 94 million cases of Salmonella gastroenteritis, with 155000 deaths, are reported each year and 85% of them reported to be food-borne. Investigation of the foods whether they are clean for Salmonella and sensitivity, easy applicability, absence of false positivity and negativity and the speed are the features sought in the analysis method for this investigation. It is not desirable for analysis to detect the presence of dead bacteria in food. Although the final product does not contain microbiologically harmful live bacteria during the food process, the detection of dead bacteria transmitted before the process causes the food product to be unfairly diagnosed as harmful. To prevent this situation, the analysis kits depending on molecular methods, increase their microorganism detection levels up to to 104 while reducing their sensitivity. Since the molecular methods cannot discriminate dead and live organisms, a confirmation test is required to prove that the positive result of the analysis belongs to the live bacteria in the food, which results in additional cost and time loss. In the same way, it is necessary to verify whether the colonies that grow in the gold standard culture method, belong to Salmonella bacteria. In the developed system; 105 dead bacterial DNA is eliminated in the food to prevent false positive results and the minimum detection limit is 10 bacteria. Also, in developed system, 4 primers specific to 6 regions of DNA are used. Therefore, the specificity of the method is very high (99.9%) and no verification test is needed. Since PCR systems require a device with complex temperature control units, they can make analysis in a laboratory-dependent manner. In the proposed system, DNA is amplified at constant temperature; no temperature cycle is required, therefore no complex instrument and laboratory infrastructure are required. All the procedures can be easily performed outside the laboratory on a portable mini-heater where pre-enrichment, DNA isolation from the sample and PCR steps are performed. For molecular analyses, the device is required to display the result of imaging or analysis. In the developed method, DNAs amplified by the loop-mediated isothermal DNA amplification method, are hybridized and combined with the labeled probe and then can be read by lateral flow method with the naked eye. As the results are visible by eye, no additional device is required. The classical culture method is accepted as the gold standard, but the duration of analysis is 7 days for positive samples, 3 days with verification test, for the molecular methods, and 5.5 hours including pre-enrichment time in the developed system.
