Technical Abstract: A portion of genomic RNA 1 of tobacco rattle tobravirus (TRV) was amplified by reverse transcription polymerase chain reaction from each of eight processed potato chips from three different bags purchased at three locations. The positive chips all had symptoms typical of corky ringspot disease, caused by TRV infection, and consisted of dark brown arcs and rings. Sequence analysis of the 463 bp amplicons confirmed that the products were indeed TRV in origin and were 97% identical to TRV sequences of isolates originating in Washington, Florida, and Wisconsin. Chip extracts were not infectious when mechanically inoculated onto tobacco leaves. To the authors’ knowledge this is the first report of the detection of plant virus genomic RNA in a processed food product.
