Health risks

Today (2023), the major part of the gm are resistant to herbicides, particularly glyphosate. It has been reported that, both the transgenic maize resistant to herbicides, such as the herbicide itself, are harmful to human health.

The safety of maize genetically modified has been challenged by various scientific studies, one of the most relevant the report of the molecular biologist frenchman Gilles-Eric Séralini in 2012, which showed that the transgenic maize NK603 Monsanto (consumed in Mexico through its import from the united States), generates damage in the kidneys and liver, as well as that it is possible generator of tumors. In addition, studies have been performed in other animals and have found a variety of adverse effects in addition to the component carcinogenic, as are alterations in the reproductive development (pre-natal and post-natal), hormones, neurotoxicity, endocrine disruption and the microbiome.

Given these effects harmful to health, it is necessary to push for labeling of food products containing gmos, and aspire to its prohibition for human consumption, direct and indirect. Also, studies have been conducted concerning the effects of transgenic-derived new methods of genetic engineering, as is the editing genetics by Crispr-Cas9, which is identified may cause cancer, removal or alteration of genetic sequences that do not seek change, the same thing happening with genes that are activated or silenced as a side effect. Again, this technology is controversial with regard to its effects on human health.

Unfortunately, we have found herbicides such as glyphosate in tortillas and other foods from the diet mexican, which in turn has resulted in the presence of glyphosate in human blood and urine.
