significant glyphosate exposure from desiccation:
2018.1.1: summary:
. increasing glyphosate exposure
may have adverse health consequences
and we are getting a lot more of it
since the 2002 practice of
using glyphosate for killing crops
to make harvesting easier.

Interdiscip Toxicol. 2013:
Celiac disease, and, more generally,
gluten intolerance, is a growing problem
worldwide, but especially in North America and Europe,
where an estimated 5% of the population now suffers from it.
It is a multifactorial disease
associated with numerous nutritional deficiencies
as well as reproductive issues and increased risk
to thyroid disease, kidney failure and cancer.
Here, we propose that glyphosate,
the active ingredient in the herbicide, Roundup®,
is the most important causal factor in this epidemic.
Fish exposed to glyphosate develop digestive problems
that are reminiscent of celiac disease.
Celiac disease is associated with
imbalances in gut bacteria
that can be fully explained by the
known effects of glyphosate on gut bacteria.

Dr. Richard Jackson and Charles Benbrook:
Why the steeply upward trajectory of
glyphosate residues in the U.S. population
between the 2004-2005 and 2014-2016 periods?
It is doubtful that the planting and spraying
of Roundup Ready crops is the cause,
since by 2004-2005, Roundup Ready technology
had already gained high levels of market penetration,
and overall glyphosate use has risen modestly
since 2005. Around 2002, farmers in the U.S.
started adopting pre-harvest,
desiccation uses of Roundup,
to speed the harvest of grain crops like
wheat, oats, and barley, as well as
edible beans and several other crops.
Such “harvest aid” uses of glyphosate entail
spraying fields about two weeks prior to harvest.
The objective is to speed up the drying of grain crops
so harvest operations can be started earlier,
and hopefully completed before onset of wet weather.

But spraying a mature grain or bean crop
so close to harvest
with a glyphosate-based herbicide
results in much higher residues
than traditional applications
done in spring or early summer.
Beginning around 2004
and over about the next decade,
incrementally more acres were sprayed
to speed up harvest in the U.S.
It is nearly certain that residues from
these applications
were largely responsible for
doubling the levels of glyphosate
and its metabolite found in the urine of
some California residents
from the 1993-1996 test period
to the 2014-2016 test period.
