Rapid and standardized methods for detection of foodborne pathogens and mycotoxins on fresh produce

Due to the increase in consumption of fresh produce regarding to the health demand in the last decades, a considerable portion of foodborne outbreaks has been trackbacked to contaminated fresh produce, which have appeared as highly possible vehicles for foodborne outbreaks nowadays. Delays in detection of pathogens and mycotoxins on fresh produce hindered the trace-back investigations in finding the source and revealed the urgent need of rapid and reliable methods. In the frame of this review, we summarized available fast, reliable and standardized methods (conventional, molecular, rapid and recently developed methods) used for detection of the most common foodborne pathogens and mycotoxins which are the most likely causative agents of outbreaks caused by contaminated fresh produce.


Molecular evaluation and antimicrobial susceptibility testing of Escherichia coli isolates from food products in Turkey
Kyere, Emmanuel Owusu; Bulut, Ece; AVŞAROĞLU ERKAN, MÜRŞİDE DİLEK; Soyer, Yeşim (Springer Science and Business Media LLC, 2015-06-01)
Some strains of Escherichia coli can be important food borne pathogens. Characterization and antimicrobial resistance testing of 28 E. coli isolates from random food samples obtained in Van, Turkey were performed. Primers for 6 indicator genes (fliC, stx1, stx2, eae, hlyA, and rfbE) for shiga toxin-producing E. coli and 5 indicator genes for each pathogroup (bfpA, aggR, ipaH, daaD, st, and lt) were used. E. coli isolates were also typed using pulsed field gel electrophoresis with the XbaI restriction enzyme...
Comparison of thermal sterilization and high hydrostatic pressure-HHP on furan formation, microbial and nutritional quality in commercial baby foods
Kültür, Gülçin; Alpas, Hami; Department of Food Engineering (2013)
Furan, which is a lipophilic contaminant and formed during heating process in foods, has been pointed out as a danger in baby foods since it has been classified as “possibly carcinogenic to human” by IARC (International Agency for Research on Cancer). Hence, a great concern has been addressed to the analysis of this substance in baby foods. This study aims to prove that sterilization of baby foods is possible by high hydrostatic pressure (HHP) without allowing the formation of furan. Firstly, HHP treatments...
Efficiency of high pressure treatment on inactivation of pathogenic microorganisms and enzymes in apple, orange, apricot and sour cherry juices
Bayındırlı, Alev; Alpas, Hami (Elsevier BV, 2006-01-01)
The purpose of this study was to investigate the effect of high hydrostatic pressure with a mild heat treatment on Staphylococcus aureus 485, Escherichia coli O157:H7 933 and Salmonella Enteritidis FDA in apple, orange, apricot and sour cherry juices. The effectiveness of the treatment on polyphenol oxidase activity in apple juice and pectinesterase activity in orange juice were also determined. An inoculum of microorganisms was completely inactivated at 350 MPa and 40 degrees C in 5min. The residual polyph...
Development of immunoaffinity based detection platforms for food pathogens
Çam, Dilek; Öktem, Hüseyin Avni; Department of Biology (2016)
Salmonella and E.coli, food pathogens, are among the very important pathogens threating the health. Rapid and easy detection of these pathogens is crucial. In this context, lateral flow assay (LFA) platform prepared by gold nanoparticles (GNPs) based on antibody for Salmonella and E.coli O157:H7 was developed in the first part of this study. In second part, single chain variable fragments (scFv) and SNAP-Tagged full IgG (fusion protein) of se155-4 antibody specific to Salmonella were genetically produced. T...
Current applications of exopolysaccharides from lactic acid bacteria in the development of food active edible packaging
Moradi, Mehran; Guimarães, Jonas T; Şahin, Serpil (Elsevier BV, 2021-08-01)
The lactic acid bacteria (LAB) are usually recognized as safe for consumption and comprise several genera with different technological and health-promoting potential for food applications, including probiotic characteristics. Their exopolysaccharides (EPS) have interesting film-forming properties and may be used to produce edible packaging, as a structural enhancer, a bioactive agent or probiotic carrier in edible films and coatings. In these days, there is a specific demand for food products with reduced a...
