I don't see that Rick.  People were ill and hospitalized.  When you serve food you take that risk.  It happened to Sekiya's in Kapahulu with e-coli.  We insure ourselves to spread out the risk of causing injury to others.  Genki and KOHA can take legal action if it chooses to.  Certainly there are more victims than those that have become ill.  How do you sue a company in the Philippines?  What court has jurisdiction?  There is nothing that can be done to change Sea Port (producer) from continuing it's behavior or to require the company to impose better health standards.  You can ban the companies product from being imported into the United States.  Do you think that the State Health Department can call the Philippine Government and tell them to shut Sea Port down.  Not a chance.  Hopefully, somebody got to Sea Port and informed them.
Example.  a drug dealer makes cocaine in Bolivia, traffics it to Los Angles, taken to New Jersey and somebody dies from an overdose.  Where do you go?
