"No GMO" is now officially an advertising gimmick...

32. Glyphosphate must be absorbed by the plant in order to work.

Washing it off will not remove what has been absorbed.

And residues can remain stable in foods for a year or more, even processed foods.

Glyphosate must be absorbed into the foliage to be translocated to the sites of action.

Glyphosate-containing herbicides are applied in large amounts to both genetically modified
(GM) crops and non-GM crops. GM crops may receive two or three applications of
glyphosate in a season [1] while glyphosate-containing herbicides may be sprayed just
before harvest onto non-GM cereals, pulses, sunflowers and oilseed crops. This is done to
remove weeds and dry out the grains, a process called ‘dessication’ [2]. Glyphosate remains
largely unchanged in non-GM plants, but GM plants will convert glyphosate into aminomethyl
phosphonic acid (AMPA), N-acetyl-glyphosate or N-acetyl-AMPA, depending on the type of
genetic modification used [3]. When conducting risk assessments of residues in food, the
European Food Safety Authority views such breakdown products as equivalent to glyphosate
[4].
Once applied, glyphosate and its break down products are transported throughout the plant
into the leaves, grains or fruit [5]. They cannot be removed by washing, and they are not
broken down by cooking [6]. Glyphosate residues can remain stable in foods for a year or
more, even if the foods are frozen, dried or processed [7]. Some processing may even
concentrate the residues; for example, during production of wheat bran the glyphosate
residues may be concentrated by a factor of four [8].
