I would disagree.
There are standards of different qualities of flowerbulbs. The lowest
quality, which is usually sold as pre-packed, or on a discounted price can
have 10% virus infection on a visual inspection. Most lily viruses do some
leaf mottling but you have to train your eyes to see them. Some lily
viruses (Lily symptomless virus) don't cause mottling at all. This virus is
very common in Lilium lancifolium. I have had infected lilies for quite a
long time, some varieties died within years, but mostly the Asiatic hybrids
and Longiflorum survived for a long time. Which is nice for my mum, she
likes flowers, and bad for me who likes healthy plants.
Here you can see Lilium Longiflorum 'White Heaven' infected with probably
Lily Mottle Virus…
(there are some other virus infected plants in this album)

Not all varieties are produced by tissue culture, and they still can be
infected, because it takes 3-5 years to have a flowering sized bulb from
TC. The older varieties which are produced by scales, the botanicals
(species and varieties) and those which are not good for cutting are not
Tissue Cultured.
Even the latest varieties can be infected. Last year I bought some Landini
bulbs and they were the most expensive bulbs on the market here, from 3
bulbs 2 were infected with Macrophomina phaseoli. I planted them in a soil
where no plants were growing for 7 years. I assume this must came with the
bulbs, and this year there was a 35% drop in the price of this bulb. The
only symptoms i saw is that they went into dormancy earlier, and din't
produced any stem bulblets in the soil. I cut the stem half and i saw the
micro sclerotia.
