Hello to All:
       Although the question has not been addressed to me, I thought
that perhaps I should answer being that I am the "father of the
creature."  Yes, I am very much aware of the existence of PGMO.  Those
who read my files will notice tht I describe the reason for selecting
FGMO with abundace of detail.  For those of you who may have missed it,
please let me state it again.  FGMO is approved by the federal
government (hence also
state governments) in the USA for use in food handling operations.
While PGMO might be slightly priced below the cost of FGMO, PGMO does
not have approval from the government as a substance that can be applied
to the "tools" for food handling.  Since honey is food, I think that the
reason should be clear to everyone especially with the possibility of
honey being subject to regulatory procedures in the near future.  With a
lifetime experience in food hygiene, I would never advocate the use of a
substance that does not meet hygienic standards.  Perhaps when the use
of mineral oil as a bee miticide (as I have not doubt that it will
become!), beekeepers and honey packers will lobby the government for
approval of PGMO as an accepted substance that can be utilized in honey
handling operations.
     I would also like to emphasize for those of you who may have missed
my post.  A few days back I posted to Bee-L the names of two major
distributors of mineral oil in the United States including their
telephone numbers; (one of them  is a free  call:    1-800-245-3952).
      Good luck to all of you in the coming beekeeping season.
Best regards.
