In California cryolite (fluoride plus aluminum) is legal to use on organic
produce. I've heard that sodium fluoride is a registered pesticide, but I
don't know if it's legal on organics.

Some foods are now being stored in large bins where they are fumigated with
sufurly fluoride to keep the bugs down. This is the same fluoride used to
kill bugs in those big tents you see put over houses. I don't know if
organic foods can be fumigated with fluoride in these bins, but I've heard
nothing to say they cannot. Because of this new practice, the fluoride
tolerance levels have been raised by the EPA far above what was considered
safe in the past.

Yes, we are all getting far more fluoride in our food these days than when
fluoridation started in the 1950. Some pro-fluoridation officials and
professor have denied this, but they are either ignorant or liars.
