Excreted glyphosate in urine of Danish cows was significantly
higher than from German cows and represents a higher intake from
feed. Interestingly, the glyphosate concentration in German dairy
cows kept in a GM free region excreted much less glyphosate than
conventionallymanaged cows. Thus, the prohibition of GM grains and
soy prevent these animals from consuming glyphosate with their feed.
Since organic farmers don`t live in an isolated area, the presence of low
levels of glyphosate could be attributed to contamination by air and rain
[2].
