Just read a post about dried papaya possibly being dusted with flour.
Please note that the same is true of those nice plump dates that don't stick
together.
One food store that I visit occasionally in Victoria BC (Overwaitea) has a
loose-leaf book in its bulk food section that gives information about the
foods and lists these 'extra' ingredients. It is not infallible, but
helpful.
