Abstract
Since the establishment of procedures for the safety assessment of food products that use recombinant DNA technology, the manufacture, import, and sale of genetically modified (GM) foods that have not undergone safety assessment are prohibited under the Food Sanitation Act. Therefore, a performance study to confirm the GM food testing operations of each laboratory is very important to ensure the reliability of the GM food monitoring system. In 2022, GM papaya line PRSV-YK-which has not yet been authorized in Japan-was selected for testing, and a papaya paste and a DNA solution were used as the test samples. With these samples, a laboratory performance study of the DNA extraction and real-time PCR operations was conducted. This confirmed that the 18 participating laboratories were generally performing the DNA extraction and real-time PCR operations correctly. However, some laboratories using certain DNA amplification reagent with some real-time PCR instruments were not able to determine the PRSV-YK detection test. This suggests that the PRSV-YK detection test may not be able to correctly detect samples containing GM papaya when performed with these combinations of instruments and reagent. In order to ensure the reliability of the PRSV-YK detection test, it is necessary to examine in detail how the combination of DNA polymerase reagents and real-time PCR instruments affects the detection limit, and to implement an appropriate solution.

Abstract
With genetically modified (GM) food circulating on the market, a rapid transgenic food screening method is needed to protect consumer rights. The on-site screening efficiency of GM food testing is low. We report rapid sample-to-answer detection of GM papayas with loop-mediated isothermal amplification (LAMP) and a compact, portable, integrated microfluidic platform using microfluidic lab-on-a-disc (LOAD). GM samples were differentiated from non-GM papaya, based on the detection of a specific GM (P-35S (Cauliflower mosaic virus 35S promoter)) and non-GM DNA marker (papain) in 15 min. The detection limits for DNA and juice from papaya were 10 pg/µL and 0.02 µL, respectively. Our LOAD platform is a simple and robust solution for GM screening, which is anticipated to be a foundation for on-site testing of transgenic food.
