Abstract

The potential transmission of plant pathogenic viruses through processed foods could be a source of concern for global crop production; however, there is a lack of supporting evidence. The present study was conducted to investigate the presence of plant pathogenic viruses in five samples of gochujang (fermented red pepper paste) manufactured in Korea. Several viruses infecting pepper were detected by reverse transcription-polymerase chain reaction, among which the pepper mild mottle virus (PMMoV) was detected in all five samples, at concentrations ranging from 2.8 to 7.0 (log10 copies/ml). In addition, PMMoV was observed by transmission electron microscopy in all five samples. The samples exhibited viral pathogenicity to Nicotiana benthamiana plants, indicating that global trade of processed products could be a possible source of the transmission of plant viruses.
