Electrochemical genosensing of food pathogens based on graphite-epoxy composite... 

Contamination of food, food pathogens and food safety... 

These growing and enrichment steps are relatively time-consuming, having a total assay time of up to 1 week in certain food pathogens [6]. Although classical culture methods can be sensitive, they are greatly restricted by the assay time. 

Rapid detection methods to detect food pathogens... 

GEC-based platforms are useful and versatile transducer materials for electrochemical DNA genosensing of amplicon food pathogens. 

For all the aforementioned reasons, it is possible to conclude that GECs-based platforms are very suitable for DNA analysis of food pathogens. 

However, the nucleic acid-based assays for the detection of food pathogens show problems regarding the sensitivity of the polymerase enzyme to environmental contaminants, difficulties in quantification, the generation of false-positives through the detection of naked nucleic acids, non-viable microorganisms or contamination of samples in the laboratory, and may limit the use of PCR for the direct detection of microbial contamination.
