One of the biggest question marks about the genetically modified organisms created by Monsanto and other companies is the issue of “substantial equivalence,” a blanket definition made by the FDA that asserts that the crops are considered to be equal to non-GMO crops.
Because of this declaration, no compulsory safety testing is required by regulatory agencies in order for a new crop to be approved and enter the market.
Making matters even more confusing is the fact that GMOs (also known as genetically engineered seeds or crops) have registered patents, which suggests that the crops must be inherently different in some pretty substantial ways from traditional ones.
Are GMOs really “substantially equivalent” to non-GMO crops? Common sense says that the definition doesn’t quite fit, and now a new study on a particular type of GMO maize has added even more fuel to the fire.
Molecular Profiling Shows: GMOs Cause Large Increases in Toxic Compounds
As mentioned in a new article from the website GMWatch.org, a new analysis using “cutting-edge molecular profiling methods” has shown once again that GMOs contain many substances that differ greatly from organic or conventional crops, and may be linked to health problems.
The study, published by Scientific Reports, found large increases in two potentially toxic compounds in NK603, while also showing that 117 proteins and 91 metabolites were altered in the maize by the genetic transformation process, the GMWatch article said.
Carried out by an international team of researchers including Gilles-Eric Séralini, who produced a study linking Monsanto corn and glyphosate to tumors in rats (it was controversially unpublished in one journal and later republished in another), the study casts serious doubt on a 2009 European Food Safety Authority GMO panel declaration.
The EFSA panel concluded that the Monsanto maize is “compositionally equivalent to conventional maize” except for just the original intended change, which is the presence of additional proteins that make the corn able to withstand sprayings of glyphosate-based herbicides such as the company’s flagship Roundup product.
But the new study suggests that the EFSA’s conclusions may were incorrect.
As the GMWatch article noted:
“The researchers’ in-depth analysis of the types of proteins (“proteomics”) and small biochemical molecules (“metabolomics”) revealed major differences between NK603 maize and its non-GMO counterpart.
“A total of 117 proteins and 91 small molecule biochemicals (metabolites) were found to be significantly altered in NK603 corn by the GM transformation process. The GMO and non-GMO maize were grown in the same location and under the same conditions, ruling out the possibility that environmental factors such as the spraying of Roundup or different growing soils caused the differences.
“Polyamines found to be present in increased amounts in GMO NK603 corn included putrescine and cadaverine,” the study concluded.
