Letter to Maseca re: flour from genetically modified corn




Hi folks,

I just wrote this letter today asking for clarification from Maseca and for them to follow up on doing the right thing by our communities and not use flour from genetically modified corn, which is produced by Monsanto in the U.S.  Please feel free to write them also to pressure them to do what they said they would do, to not use frankenstein corn.  Here is the page where you can write them – http://www.mimaseca.com/en/maseca-responde-tus-dudas/



First is the Spanish, then the translation.        




Muy buenas tardes.

Me gusta mucho hacer tortillas con Maseca, pero vi que usan harina que viene del maíz  modificado genetícamente que hace Monsanto, o sea, de las semillas modificadas genetícamente.  Estan saliendo unos estudios scientificos que demuestran que la comida que viene de semillas modificadas genetícamente esta dañando la salud de nuestras comunidades.

Además, como colombiano, entiendo bien la muerte que trae Monsanto con la fumigación del pulmón del mundo, la zona Amazonica y las comunidades ahí.  Me parece que no se le puede tener confianza a dicha corporación en relación a la comida para nuestras comunidades.

Además oí que ustedes anunciaron recientemente que van a parar de usar ese maíz.  Queria saber cuando lo van a hacer para poder comprar su producto de nuevo en ese entonces.

Como empresa mexicana, me parece que sería bien respaldar a los agricultores mexicanos, no les parece?

Se lo agradecería mucho recibir una respuesta a este asunto importante.

Muchas gracias,
Rafael A. Mutis

Good afternoon.

I really enjoy making tortillas with Maseca, but I see that you use flour that comes from genetically modified corn made by Monsanto, or rather, from seeds which are genetically modified.  Some scientific studies are beginning to come out which show that food which comes from genetically modified seeds is damaging the health of our communities.

In addition, as a Colombian, I understand well the death that Monsanto brings to the lung of the world, the Amazon basin and the communities there.  It seems to me that we cannot trust that corporation in relation to food for our communities.

In addition, I heard that you announced recently that you will stop using that corn.  I want to know when you will do so so I can again begin to buy your product then.

As a Mexican company, I think it would be good to support Mexican farmers, don’t you think so?

I would really appreciate a response to these important issues.

Thank you very much,

Rafael A. Mutis

  1. Hello, I found your post after doing a search to see if Maseca’s Masa Harina was GMO or not. I wanted to say kudos to you for contacting them in regards to this important issue. I will also send them an email! Just curious, has the company replied to your letter yet? Like you, I refuse to purchase their products until I can be guaranteed that they use non-gmo corn.



    • Thank you for your kudos and words. I still have not heard back, but I have heard that Mexico has said no to GMO corn. I’m not sure how that will happen, since they destroyed their own domestic agricultural industry with the advent of NAFTA, but it seems hopeful.

      Keep up the fight!

      Cool blog!



      • As promised, I sent Maseca an email and I have included their response below. The only widely available brand (that I am aware of, that is) that sells non-GMO corn flour products is Bob’s Red Mill.

        Dear Customer;

        Azteca Milling LP, a producer of corn flour, uses only corn from varieties developed in the United States to be then planted and harvested as well in the United States.

        United States Government approves the use of all commercially available GMO corn varieties for human consumption, therefore, the corn purchased and processed into corn flour by Azteca Milling L.P. may or may not contain GMO material, since both are planted throughout the country.

        The only GMO corn that Azteca Milling L.P. tests is Starlink, a GMO yellow corn variety that was developed and produced only for animal consumption which is no longer produced and planted. We are still testing it because the EPA has not taken it off the list of un-approved for human consumption.

        Azteca Milling L.P., maintains continuous attention to this matter due to the sensitive effect of genetic modifications in our food supply.

        Best Regards.


      • Great. Their response is interesting. There was just a decision in a Mexican court outlawing gmos, so we will see how that works. Here is a brief summary – http://healthimpactnews.com/2014/mexican-judge-throws-out-monsanto-appeal-to-challenge-gmo-corn-ban/

        Take care!
