I received one response to my query on chopped dates.. Basically there is,
in this persons statement (I don't know how justified) a good chance of
wheat flour being present unless the product is marked kosher for passover.
I didn't try to talk to the companies about it. I haven't found this very
usefull anymore since they sometimes just try to tell you what they think
you want to hear.
Sorry the response wasn't greater.
