“…These parameters can be divided into technical parameters such as detection limit, time of analysis, validation of the method, sensitivity and specificity, and additional parameters like equipment, operation, and costs (De Boer and Beumer 1999;Swanenburg et al 2005;Meloen et al 2001;Ivnitski et al 2000;von Blankenfeld-Enkvist and Brännback 2002). In the case of a suitable method for detection of Salmonella in fresh poultry meat with the purpose to steer the destination of the finished products, the parameters of the method should fulfill the requirements, which are discussed below.…”

In the perspective of an announced prohibition to bring Salmonella-contaminated fresh poultry meat on the retail market as of December 2010, requirements are postulated for rapid methods for detection of Salmonella in poultry meat. These rapid methods should deliver reliable results in time to make it possible to steer the finished products in poultry slaughterhouses into the direction of the fresh poultry market or into the direction of industrial treatment. The most important requirements are the detection limit (1 cfu/25 g), the time of analysis (within hours up to a maximum of 24 h), the sensitivity and specificity, and the validation of the rapid detection method. To determine a requirement for the number of samples to be analyzed per unit of time of the detection methods, a sampling plan for pooling of samples is suggested. Information of commercially available detection methods from literature and data provided by the suppliers was compared to the postulated requirements. The results showed that none of the commercially available detection methods meet all the suggested requirements. For all available methods, the time of analysis is too long to steer the production process in time. This implicates that faster methods should be developed before the announced prohibition can be sensibly introduced. Also, information about sensitivity and specificity, which is essential for the reliability of the rapid test method, should be examined in a more uniform way.

“…Recently, various biosensors have been developed for pathogenic bacteria detection because of their improved speed, sensitivity and reliability. Sensitivity of a conventional biosensor is between 10 3 and 10 4 cfu/ml with an assay time around 2 h under ideal conditions (Ivnitsk et al, 1999(Ivnitsk et al, , 2000Rand et al, 2002;Su and Li, 2004).…”

The realization of rapid, sensitive, and specific methods to detect foodborne pathogenic bacteria is central to implementing effective practice to ensure food safety and security. As a principle of transduction, the impedance technique has been applied in the field of microbiology as a means to detect and/or quantify foodborne pathogenic bacteria. The integration of impedance with biological recognition technology for detection of bacteria has led to the development of impedance biosensors that are finding wide-spread use in the recent years. This paper reviews the progress and applications of impedance microbiology for foodborne pathogenic bacteria detection, particularly the new aspects that have been added to this subject in the past few years, including the use of interdigitated microelectrodes, the development of chip-based impedance microbiology, and the use of equivalent circuits for analysis of the impedance systems. This paper also reviews the significant developments of impedance biosensors for bacteria detection in the past 5 years, focusing on microfabricated microelectrodes-based and microfluidic-based Faradaic electrochemical impedance biosensors, non-Faradaic impedance biosensors, and the integration of impedance biosensors with other techniques such as dielectrophoresis and electropermeabilization.

“…The enzymes, antibodies and nucleic acids are the main bioreceptor classes that are mostly used in biosensors applications. In general, they are immobilized on a support which can be the detector surface, its vicinity or a transporter (Ivnitski et al, 2000;Lazcka et al, 2007;Oh et al, 2005;Radke & Alocilja, 2005;Velusamy et al, 2010). The biosensors classification according to the nature of the variable parameter converted by the transducer in electric signal can be seen in Figure 1, but a more complete classification is given in Figure 3.…”
