Well that's rather an alarmist take. If we use the film as a basis, you're right. There is the potential for disaster. If you get these creatures wet, they multiply, rather like the Tribbles. Feed it at the wrong time, and it will transform into a being that will wreak havoc. But I think we're all well-prepared enough to deal with the consequences of either scenario, should anyone be foolish enough not to follow the rules.
