Rapid monitoring of SARS-CoV-2 on fruits and vegetables using reverse-transcription loop-mediated isothermal amplification assay

COVID-infected people handling fruits and vegetables may spread the virus to healthy people on contact. Here we examined if SARS-CoV-2 was detectable on the fruits, vegetables, hand gloves and packaging materials collected from the open markets and pack houses in India. During the study (2021-22), swabs from 748 samples representing the majorly traded items were tested using RT-LAMP assay. The sensitivity and specificity of the kit were found to be equivalent to the RT-PCR assay. All test samples were found negative for SARS-CoV-2. Thus, it can be concluded that the virus is unlikely to spread to foods and packaging materials through human contact.
