TUESDAY, Oct. 24, 2017 (HealthDay News) — Levels of the herbicide Roundup in human urine have increased dramatically among California residents inside the past two decades, a brand new study reports.
Roundup (glyphosate) is usually used to protect genetically modified corn along with also also soy crops by weeds along with also also also is usually used on wheat along with also also oats, said the study’s lead author, Paul Mills. He is usually a professor of family medicine along with also also public health at the University of California, San Diego.
Urine collected by 100 Californians between 1993 along with also also 2016 show of which glyphosate levels have gone up with the advent of genetically modified crops, Mills said.
inside the early samples, “there were very low levels — they were only detectable in 12 out of 100 people,” Mills said. “Then over the next 22 years, we found about a 1,000 percent increase inside the levels found inside the 100 people, on average.”
However, the study does not show of which exposure to glyphosate directly caused any health problems in these people, noted Dr. Nima Majlesi, director of medical toxicology at Staten Island University Hospital in brand new York City.
“I think these studies have a huge flaw in of which they actually haven’t shown any adverse outcomes in human beings,” Majlesi said. “All you’re seeing is usually numbers.”
Some strains of corn along with also also soy have been genetically altered to render them immune to Roundup, allowing farmers to spray the herbicide without fear of damaging their crops. However, there’s some scientific dispute regarding Roundup’s potential hazard to humans.
In 2016, the entire world Health Organization concluded of which “glyphosate is usually unlikely to pose a carcinogenic risk to humans by exposure through the diet.” In July, though, California became the first U.S. state to add glyphosate to its list of known carcinogens.
For the study, Mills along with also also his colleagues made use of urine samples of which had been collected along with also also preserved for years as part of a long-term study of healthy aging. They tested those along with fresh samples in 100 people for the presence of both glyphosate along with also also aminomethylphosphonic acid (AMPA), an organic chemical produced when the body processes glyphosate.
Average glyphosate levels in urine increased by 0.024 parts per billion inside the 1993-1996 samples to 0.314 parts per billion inside the 2014-2016 samples, the researchers found.
The average levels inside the newer samples reached as high as 0.449 parts per billion after the researchers excluded people with non-detectable levels of glyphosate.
Glyphosate, widely used in residential landscaping, has been found in drinking water, although Mills believes the levels in human urine increased mainly by people eating foods exposed to the herbicide.
“the item’s unlikely of which all these folks are spraying of which much Roundup in their yards every day, to get the levels we observed,” he said.
Though the study focused on Californians, Mills noted of which Roundup is usually “the most widely used chemical herbicide inside the entire world” along with also also of which similar results would certainly probably be found across the United States.
“Our research is usually showing of which a lot of us across the U.S. likely have fairly significant levels of these compounds, unless we take up an organic diet,” he said.
Mills noted of which animals fed low doses of glyphosate have wound up with liver damage akin to fatty liver disease, adding of which “we could have found a signal why so many people are having of which increase in liver disease.”
However, Majlesi said of which the increased glyphosate levels detected inside the study are tiny.
“Even though they’ve gone up, you’re talking about miniscule amounts inside the urine of which mean very little, clinically,” he said. “There are levels of which are rising, although what do those levels mean? I think of which’s where people start to over-interpret data.”
Mills said his team does have medical data on the people inside the study, along with also also in their next phase of research the researchers will examine whether exposure to Roundup has caused any health problems.
inside the meantime, both Mills along with also also Majlesi said of which people concerned about exposure to glyphosate should consider buying certified organic foods.
“Wash your fruit, along with also also be aware of the fact of which if you’re not buying organic, the item probably is usually protected by glyphosate,” Majlesi said.
The study was published Oct. 24 inside the Journal of the American Medical Association.
