A famous study suggests that the popular Roundup might be related to the hepatic illness.
A group of patients who were enduring a hepatic illness had high glifosato levels in the urine, the main ingredient to eliminate the weeds in Roundup, according to investigators of the University of California, San Diego (UCSD).
"We think that the patients who had a more serious illness had higher levels of excretion of [glifosato], what means that they had higher exhibition levels, probably across its diet", said the main investigator Paul Mills. He is the director of the Center of Excellency for Investigation and Training in Integral Health of UCSD.
Till now, the debate on the effects of the glifosato in the health has centred to a great extent on the fears of that the chemist causes cancer.
At the beginning of this month, a jury of California granted 2 million $ to a couple who said that the long-term exhibition not Hodgkin did the Roundup that they were developing the same type of cancer, the linfoma, with four difference years.
That happened days after the Agency of Environmental Protection of the United States (EPA) was expressing a draft of conclusion that the glifosato "does not present risks for the public health" and "it is not probable that it is carcinogénico for the human beings".
Dr. Kenneth Spaeth is a chief of occupational and environmental medicine in Northwell Health in Great Neck, New York. Another area of potential reason said that the finds of the study of the UCSD with regard to the hepatic illness raise "to worry for this product and its use generalized in the whole world."
The glifosato is the herbicide most used in the United States, said the investigators. The herbicide was developed and patented by Monsanto in the decade of 1970, and it represents approximately half of the annual income of the company.
The ultimate parent of Monsanto, Bayer, it expressed a bulletin in which it indicated that a previous investigation needed to take the product to the market has demonstrated that the glifosato is sure.
"All the pesticides, including the glifosato, are analyzed by its potential of damaging the hepatic function in tests that are based on recognized protocols internationally and are realized in accordance with the good laboratory practices", said Bayer. "All these tests demonstrate that the glifosato does not damage the hepatic function".
Mills said that he was interested by the possible effects of the glifosato in the liver after studies that demonstrated that rats and laboratory mice fed on the chemicals stretch to develop a form of illness of the greasy liver not related to the consumption of alcohol.
To see if the herbicide might be related to a similar illness in human beings, Mills and its companions examined samples of urine of 93 patients suspicious of having an illness of the greasy liver.
Liver biopsies took to determine if the patients had hepatic illness and the gravity of its condition. Urine samples took to determine its exhibition to the glifosato.
The investigators thought that the glifosato residue was significantly major in patients with hepatic illness that in those with a healthier liver. Also there seems to be a relation dependent on the dose: all the more glifosato there is in the urine, worse it is the health of the liver of a person.
In its declaration, Bayer said: "Although we are still examining this study recently released, the information indicates that the investigators did not consider the possible existing metabolic disorders to be factors of confusion, included in the participants, what would do that the results of the study were not reliable".
Although the study could not prove the cause and the effect, the investigators said that the finds kept on being significant even after bearing in mind the age, the race / ethnic group, the corporal fat and the diabetes state.
Mills said: "Bearing in mind these questions, I would like that the EPA was saying 'we are going to throw another glance to this'".
The glifosato might damage the liver of several ways, he suggested.
The chemical substance might interfere with the aptitude of the liver to process the fats and to do that they accumulate in the organ. Or it might damage the genes that regulate the metabolism of the fats in the liver.
The glifosato is used to improve the yields of the commercial cultivation on having eliminated the weeds that they would drown to the plants, therefore big part of the exhibition of a person to the chemist stems probably from the diet, said Mills.
The best way of being protected would be to adopt an organic diet, eating only food that have not been cultivated by herbicides or pesticides, he told.
On having observed that its study was small, Mills hopes that other investigators should do a pursuit to major scale to examine the effects of the glifosato in the liver.
"I hope that other laboratories in the whole country that should have hepatic centers or other available samples also should examine it and should see what type of sign they find", he said. "That would help us to advance".
