Is meat from wild game in treated areas okay to eat?

Category: Health

Yes. Both lab and forest studies show that glyphosate does not accumulate in the tissue of animals living in treated areas. A moose study by Wolastoqey Nation in New Brunswick (WNNB) found glyphosate was not detected in tissue samples and showed that moose meat is not a source of glyphosate in the diet of humans.

Based on laboratory studies, glyphosate does not bioaccumulate in tissues and is known to be rapidly excreted in the urine and feces of experimental animals even when exposed at very high experimental dose levels (Williams et al. 2000). Newton et al. (1984) reported that mammalian herbivores, carnivores and omnivores had visceral and body contents at or below observed levels in ground cover and litter and that residues were largely associated with the viscera (presumably largely in the digestive tract) and that other non-visceral body parts contained residues less than 0.5 ppm in all cases. Couture et al. (1995), summarizing results of studies conducted in Quebec, reported no detectable glyphosate residues in meat or liver of hares, moose or deer (1 sample only) collected in the hunting season (2 months after treatment), despite measureable residues in stomach contents, urine and feces of these animals. One of 19 kidney samples taken from hare contained a measureable level (0.208 ppm) of glyphosate.

Launtenschlager has reported results of a study, which investigated residues of glyphosate in moose meat from an area, which had been treated approximately two months before sampling. The authors reported that glyphosate residues were detected in only one sample out of 31 tested and that this single positive finding was likely the result of contamination.

Glyphosate forestry products are also used in agricultural settings, and it is therefore expected that the exposure to glyphosate from food products (i.e., fruits and vegetables from direct treatment with glyphosate) or animal commodities such as meat, milk and eggs (derived from livestock animals exposed to glyphosate -treated feed) will cover potential exposure from inadvertent residues in moose following a forestry use. The potential inadvertent exposure from consumption of moose meat is therefore not of concern.

In April 2015, the PMRA released their latest review of glyphosate and declared that the weight of evidence indicates that glyphosate does not present unacceptable risk to human health.
