First off, we need to contain the situation. The ship may still have zombies onboard, so a perimeter needs to be set up around the ship and no one should be allowed on or off of it. Secondly, quarintine the victims, both living and dead. We don't want an accidently infection started up because of them. Thirdly, we need response teams set up so that if an incident is called in, we can respond to it immediately with the plan of containing the area to keep it from spreading.

IMO our primary goal is first to keep it contained. Once its contained to specific area, then we deal with removing the problem.
