Investigation of potential safety hazards during medical waste disposal in SARS-CoV-2 testing laboratory

Abstract: This study aims to investigate the potential safety hazards and provide reference for improving the medical waste disposal procedure in SARS-CoV-2 testing laboratory. Our SARS-CoV-2 testing group detected the RNA residue on the surface of medical waste with Droplet Digital PCR, and held a meeting to discuss the risks in the laboratory medical waste disposal process. After effective autoclaving, SARS-CoV-2 contaminated on the surface of medical waste bags was killed, but the average concentration of viral RNA r… Show more

“…Among these, RT-qPCR is widely used for the detection and relative quantification of SARS-CoV-2 nucleic acid targets. However, this method suffers from false-positive results (FPRs) and false-negative results (FNRs) when quantifying less abundant targets ( 21 24 ). Moreover, RT-qPCR relies on a standard curve to relatively quantify nucleic acid targets ( 25 ).…”

“…Medical waste should be sustainably managed to avoid adverse effects on the environment and living things (Romero & Carnero, 2019). During COVID‐19, many risks were involved in medical waste management (Lv et al, 2021). During the pandemic, proper medical waste management for public health care organisations became a major challenge in social, economic, environmental, logistics and operations aspects (Babaee Tirkolaee & Aydın, 2021).…”

“… Di Maria et al (2021) detected SARS -CoV -2 RNA on 15% of 1175 samples of solid waste such as plastic coffee cups, plastic glasses, beverage cans, and plastic bottles that contained saliva with a viral load ranging from 4.8 × 10 3 to 4.0 × 10 6 genome copies/swab. Pertaining to medical waste materials, SARS-CoV-2 RNA has been detected on outer surface of medical waste bags ( Lv et al, 2021 ) , surgical masks ( Hu et al, 2020 ; Pasquarella et al, 2020 ; Dargahi et al, 2021 ), PPE of health care worker ( Peyrony et al, 2020 ), used gloves ( Ye et al, 2020 ), PPE of medical staff including aprons and face shields ( Krambrich et al, 2021 ) and outer part of the N-95 masks ( Dargahi et al, 2021 ). In the above studies, only Hu et al (2020) and Krambrich et al (2021) tested viral infectivity.…”
