Glyphosate in corn

Corn has been conspicuous in the CFIA not by its absence, but by absence of glyphosate from it. We understand most of the corn grown on industrial scale in north America as well as elsewhere may be RoundUp ready and laced with glyphosate. And yet, it shows up with relatively low concentration in comparison with some other crops such as say wheat or chick pea.

Corn story, on around 6,000 CFIA test records

While the reason for this deserves to be investigated separately, the CFIA readings as they stand, can also throw light on country specific data as well as data on which kinds of corn based food shows up with how much glyphosate. The table here is based on country profile from some 250 odd tests done on corn based foods out of about 6,000 total tests from CFIA.

The largest block among countries is, again, unknown. I suspect most of these to be of Canadian origin. Anyhow, the general average glyphosate and AMPA count per sample of corn based food tested by CFIA that originated from Canada or “Unknown” are 3. The country at the top of the list is USA, followed by Italy and Mexico.

USA
For USA, glyphosate starts showing up in some corn starch, and a lot of corn based pre-cooked meal, also often described as called cornmeal in one word.

Italy
In the case of Italy, there are many samples of corn based food with no glyphosate. However, their average seems to have been spoiled by a few cases of food items identified as San Zenone Organic Corn pasta, which show over a hundred ppb. So, in the case of this particular food description, even organic is contaminated. Many other kinds of corn based organic and conventional pasta, such as Penne Rigate, gluten free organic corn pasta – are without glyphosate. However, some but not all of the same Penne Rigate, but without the “organic” in it, has glyphosate.

Mexico
Mexico had a near perfect reading of zero glyphosate in foods originating from there. But it has been spoiled by some corn based foods such as taco shells, tortilla and corn chips.

Canada + Unknown
Among corn based foods from “unknown” and Canada,  tortilla, chips, corn flakes and corn bran are among the culprits, having detectable amounts of glyphosate.

Thailand, Philippines & China
Although the sample base is smaller, corn based foods from these countries as tested by CFIA appear to contain no measurable glyphosate or AMPA at all. Out of these, China’s story could be controversial since it is a heavy producer and consumer of glyphosate laced food. We are told that China also grows smaller quantities of organic food and is very careful in ensuring that only organic stuff is exported so that their market and reputation is not spoilt.

Glyphosate Screen Positive
Apart from all above, a large number of glyphosate screen test shows positive (as against negative) for many food types and that includes corn. Most of the positive results come from samples originating from the US, with much lesser numbers from other nations.

Thats it for now.
