Summary: The increasing demands for food, lack of arable land, and limited water resources pose important challenges for humanity in the century ahead. Food-related diseases have been on the rise and have significant impacts on the global economy. Therefore, ensuring food safety is essential and should be taken into consideration by health policy makers. In recent decades, there have been significant improvements in laboratory diagnosis of foodborne pathogens, aiming to increase accuracy, sensitivity, and decrease the time and facilities required for diagnostic tests. Loop-isothermal mediated amplification (LAMP) is a simple and sensitive rapid test that reduces the dependency on current facilities required for conventional molecular methods. The incorporation of laboratory sciences with engineering has also led to the development of a new approach called lab-on-a-chip, known as a point of care (POC) diagnostic method. Here, we provide a state-of-the-art review on available diagnostic techniques from conventional PCR to microfluidic LAMP for the detection of foodborne parasites.

Summary: Lab-in-a-Package is a novel food packaging platform that allows sampling, concentration, and detection of pathogenic bacteria within closed food packaging without opening it. The platform utilizes an inclined food packaging tray and a reagent-infused membrane to maximize fluid localization and serve as a reagent-immobilizing matrix and an antifouling barrier for the sensor. It is validated using a newly discovered Salmonella-responsive nucleic acid probe, enabling hands-free detection of target pathogens at a level of 10(3) colony forming units (CFU) g(-1) in packaged chicken. Real-world in situ detection is simulated using a handheld fluorescence scanner with smartphone connectivity.
