The presence of glyphosate residues in organs and meat of cattle
is not a surprise since cows excretesignificant amounts of glyphosate
in urine. An animal study with Sprague-Dawley rats reported that
approximately 35-40% of the administered glyphosate dose was
absorbed from the gastrointestinal tract so that urine and feces were
equally important routes for elimination after one oral application
[24]. These authors also found that glyphosate accumulated in bones.
Considering the strong chelating stability of glyphosate for calcium,
accumulation in bones is not surprising. Our own results showed that
glyphosate is detectable in intestine, liver, muscle, spleen and kidney
tissue
