Salmonella Serovars

Conventional methods for detection of Salmonella serovars in foods are generally time-consuming and labor intensive. A real-time PCR method has been developed with custom designed primers and a TaqMan probe to detect the presence of a 262-bp fragment of the Salmonella-specific invA gene. The method has been tested with a total of 384 field-isolated Salmonella serovars and non-Salmonella stock strains, as well as 420 U.S. Food and Drug Administration food samples, comprising a variety of food matrices. The method was highly specific in detecting Salmonella in spiked chili powder and shrimp samples, with a sensitivity of 0.04 CFU/g. In addition, the method is faster, more accurate, and less costly than the traditional U.S. Food and Drug Administration's Bacteriological Analytical Manual cell-culturing and the AOAC International–approved VIDAS methods to detect Salmonella in foods.

Detection And Quantification

The aim of the present study was the implementation of molecular techniques in the detection and quantification of allergic substances of peanut in various kinds of food products, e.g., breakfast cereals, chocolates and biscuits that are frequently related to allergies. In some cases, the presence of peanuts can be due to contamination during production and are not declared on the label. A total of 152 samples were collected from supermarkets and were analysed by a Real Time PCR method. The results indicated that 125 samples (83,3%) were found positive in peanut traces but the most important finding is that from the 84 samples that had no allergen declaration for peanuts, 48 (57,1%) of them were found positive. In conclusion, Real Time PCR can be a very important tool for the rapid detection and quantification of food allergens.

Seed Dna

The detection of potentially allergenic foods, such as sesame seeds, in food products is a major concern for the food-processing industry. A real-time PCR method was designed to determine if sesame seed DNA is present in food products. The PCR reaction amplifies a 66-bp fragment of the sesame seed 2S albumin gene, which is detected with a sesame-specific, dual-labeled TaqMan probe. This reaction will not amplify DNA derived from other seeds present in baked goods, such as pumpkin, poppy, and sunflower seeds. Additionally, this assay will not cross-react with DNA from several tree nut species, such as almond, Brazil nut, cashew, hazelnut, and walnut, as well as four varieties of peanut. This assay is sensitive enough to detect 5 pg of purified sesame seed DNA, as well as sesame seed DNA in a spiked wheat cracker sample.
