Re-read "A 2015 study by the Canadian Food Inspection Agency found glyphosate in 30 percent of 3,200 food products. Similar studies have found glyphosate exceeding maximum residue limits (or MRLs) in Cheerios, beer, and wine."
The first sentence is saying a DETECTABLE amount of glyphosate is found in 30% of a huge number of food products.
The second sentence is saying excessive amounts have been found in some of these three specific food products.
Put together, it sounds like 30% of products have excessive glyphosate in them, but if you go back to the source [0], you'll find that:
"The overall compliance rate for these surveys, based on Canadian Maximum Residue Limits (MRL), was 98.7 %. No samples of fruits and vegetables, soy products, or infant foods were found to contain residues exceeding Canadian limits."
So 30% contain detectable residue, 1.3% contain residue above the Canadian MRL.
(Which, hey, room for improvement in compliance, but it's deceptive to act like 30% of food is above the MRL.)
