Commendable to get this issue in the news and public awareness, but Hawaii definitely needs a comprehensive guide and resources as well as additional research.  I have read a lot of conflicting information and "we just don't know" from experts.  This article says water catchment is a risk; others have said no.  Does a certain level of filtration and UV water treatment mitigate the risk?  I don't think anyone knows.  This article is the first I've seen to talk about washing produce in a vinegar solution; others have said salt.  And probably no testing has been done to know what concentrations may be actually effective.  It is well past time for Hawaii to take aggressive action on this public health threat.
