Toxic dose

Ready-to-use prediluted glyphosate products rarely cause toxicity after ingestion.

In adults, ingestions of 5 to 50 mL of glyphosate concentrate may result in no symptoms or minor gastrointestinal symptoms only. Moderate symptoms occur with 50 to 100 mL of the concentrate, and severe symptoms are likely when 100 mL or more of the concentrate is ingested.
