Please pardon the commercial message here, but the LM issues raised here are why our company has seen such a growth in the use of Chlorine Dioxide in various process stages in the seafood industry........this chemical solution can dramatically reduce/eliminate listeria mono. on most seafood products.

Yes, but if the product comes contaminated already, the environmental
programs for sushi (especially the ones containing sashimi) operations
would be useless. Remember freezing prevents the growth of bacteria, but
it doesn't effectively kill them.
If the operations at the vessel levels are good, I would add a listeria
test just as a confirmation. A negative test with accompanying CoA would
do it for the lot (and lots are usually big).
Listeria in fish like salmon are extremely (and scarely) common. Until
couple of years ago nobody really worried about it. However, with the
sushi industry booming, it makes it very risky not to have this hazard
controlled.
Another fact to be considered is if this product will make to the US,
which has a zero tolerance for Listeria. If not, I wouldn't worry about
it as many other countries allow it to a certain level.
