Are Your Beloved Tortillas Sprayed with Trouble?

In the heartland of tortilla consumption, where every meal seems incomplete without the comforting embrace of a freshly made tortilla, there's a culinary conspiracy afoot. Glyphosate and glufosinate, the dynamic duo of herbicides, have stealthily infiltrated the world of corn production, leaving us wondering if our beloved tortillas are unwittingly harboring more than just masa magic.

Mexico, the land of vibrant traditions and rich culinary heritage, boasts an average per capita consumption of 196.4 kg of corn. A staggering 66.1 kg of that corn metamorphoses into the beloved, pliable discs known as tortillas. But here's the catch – our favorite flatbreads might be carrying an unexpected hitchhiker in the form of glyphosate and its sidekick, glufosinate.

These herbicides, renowned for their weed-walloping prowess, are not just confined to the fields. They saunter into our kitchens through the very corn that gives life to tortillas. Alarming studies suggest a link between glyphosate and glufosinate and the onset of diseases like cancer, along with potential damage to our intestines, liver, and kidneys. It's time to take a closer look at the hidden ingredients in our daily masa delight.

Enter the Pesticide Residue Laboratory, a clandestine hero fighting the herbicide heist in our tortillas. Nestled within the National Laboratory for Food Safety Research at CIAD's Regional Coordination in Culiacán, this crack team of culinary sleuths is on a mission to unmask the true nature of our tortilla treasure.

Their battleground? The very essence of tortilla creation. Glyphosate, aminomethylphosphonic acid (AMPA), and glufosinate are under the microscope, with the team tirelessly working to quantify their presence in corn tortillas. It's a culinary CSI, but with fewer fingerprints and more chemical compounds.

Cooking Up Answers

The tortilla-making process, a masa and heat, introduces a fascinating twist. Can the thermal treatment applied during cooking dance the herbicides out of our beloved tortillas? The researchers at CIAD are determined to find out, challenging the assumption that the relatively short cooking time of masa-tortilla may not be enough to banish these unwanted guests.

Preliminary results reveal a tantalizing tidbit – during the tortilla's sizzling affair with the heat, AMPA takes a hit, experiencing a more substantial degradation. However, the tag team of glyphosate and glufosinate remains resilient, refusing to bow out gracefully. These findings are the breadcrumbs leading the researchers deeper into the labyrinth of tortilla production, leaving us all on the edge of our seats, wondering if our daily indulgence is a potential source of chronic herbicide exposure.

Behind every culinary hero, there's a supporting cast, and for CIAD's Pesticide Residue Laboratory, that role is played by the National Council of Humanities, Science, and Technology (Conahcyt). Their backing, in the form of the research project titled: Monitoring and tracking of potential routes of dispersion of transgenic sequences and herbicide residues in corn and derived products for human consumption. This paves the way for a safer, more transparent culinary landscape in Mexico.

As the research inches closer to unveiling the secrets of herbicide persistence in our tortillas, we're left pondering the true cost of our daily indulgence. Are we unknowingly ingesting a side of herbicides with our tacos, or is the culinary curtain about to rise on a herbicide-free tortilla utopia? The stage is set, the tortillas are in the spotlight, and the culinary world is holding its breath for the grand finale of this herbicide problem.
