For dry foodstuffs, you can microwave it when you bring it on the boat,
but
obviously this doesn't work with metal stuff. I've also heard that when
you
store rice, flour, etc., seal up a little piece of dry ice with it and the
CO2 will kill them. However, how many of us carry dry ice in the real
world?


There are plenty of truly airtight containers available into which you can
transfer dry goods before bringing them aboard. The simplest and best are
Ball canning jars, if you don't have little kids who can't manage glass
safely. In addition to the usual ring and cap lids, which are really meant
for canning, they also make plastic lids to fit both sizes of jars. In the
same section of the supermarket, you can usually find funnels made
especially to fit the jars, to make it much easier to pour stuff into them.
