Mass produced mericlones have been the biggest issues, especially Phalaenopsis. I have refrained the purchase of them generally, those statistics are very high. Most everyday phal growers don't care, I am not suprised, and I doubt the profit driven mericlone producers would throw out their whole batch because of a virus. I've caught phal viruses before, and I returned a plant (...no suprise the plant was put back on the shelf and sold again)
Support your hybridizers and true hobby vendors rather than your grocery store phal businesses.
I only consider seedling grown plants low risk for viruses now. And I rarely use clippers anymore, but I snap spikes and dead leaves and pseudobulbs off. Mericlones are not grown too closely together with seedling grown plants.
