Genki Sushi and Koha Foods very probably are more victims than anything else.  Their business is in the toilet from the bad publicity they have recieved.  They likely thought that buying their seafood from a reputable and licensed Washington state source was sufficient diligence.  Sea Port Foods bears a greater level of culpability, as they purchased the scallops from an inadequately supervised firm in the Phillipines, but where did the contamination come from there?  I don't see Mr. Marler going after Sea Port Foods when they really should be the target.  Follow the money...who has the deepest pockets?  I would really like the opinion of an epidemiologist as to the practicality of vaccinating every food service worker in a tourist area against Hep A.
