EPA Raises Levels of Glyphosate Residue Allowed in Food

50. I'm not sure you fully understand what you just posted

You do realize the authors are talking about intentional or accidental ingestion of relatively large amounts of Roundup, and not exposure due to pesticide residue, yes?

>85 ml is more than 1/3rd of a cup in imperial or US measure. So there's a good reason for placing Roundup out of the reach of children, just like lots of other household chemicals. There's also recorded instances of some ingesting >500ml (more than 2 cups) with mild to moderate effects.

Between 1 January 1980, and 30 September 1989, 93 cases of exposure to herbicides containing glyphosphate and surfactant ('Roundup') were treated at Changhua Christian Hospital. The average amount of the 41% solution of glyphosate herbicide ingested by non-survivors was 184 +/- 70 ml (range 85-200 ml), but much larger amounts (500 ml) were reported to have been ingested by some patients and only resulted in mild to moderate symptomatology.

So basically if you ingest >85 ml of roundup you might die, or you might just get a mild case of the shits. Also keep in mind that ingestion via pesticide exposure to produce is measured in parts per million and roundup doesn't bioaccumulate in the body.
