If a visual inspection and culling of obvious defective units is part of
the normal fill process, which it invariably is, this process is done for
media fills, and defectives are culled and rejected without incubation,
just as defective product units would be removed and not sold. To
incubate obviously defective items which would normally be removed and
rejected in the normal process, is absurd.
