Glyphosate Reality:

Non-science used as science

I have read with interest the article on “Science, Non-science and Nonsense” written by Dr. Sarath Gamini De Silva in “The Island” of 11.3.2021. In this article “Dr. Sarath Gamini”, as he is popularly known in the medical circles, refers to me (without mentioning my name) and my research and a lecture given by me to the Sri Lanka Medical Association. This is my response to him, particularly, on the issue of glyphosate pesticide.

I take strong issue with Dr. Sarath Gamini’s erroneous characterisation of my research, related to glyphosates, and the categorization of the government decisions and policies related to the glyphosate pesticide. For clarity, let me reproduce the paragraph on glyphosate in toto from Dr. Sarath Gamini’s article, highlighting the area where he refers to me and my research:

“The campaign conducted blaming the weed killer glyphosate as a cause of the epidemic of chronic kidney disease of unknown origin in the farming areas, mainly in the North Central province, was one burning issue then. There was no scientific evidence to prove this, despite the efforts of some professors in the medical field to find some. However, the importation of the chemical was banned mostly due to political expediency. One is not aware of any other country in the world doing so. When a visiting Sri Lankan expatriate doctor claiming to be a researcher in the field was asked, he could name only a small country, still contemplating doing so. He was lost for words to answer probing questions on the matter. His research has since been discredited in the USA. How the ban adversely affected the productivity in the agricultural sector in Sri Lanka has never been assessed or discussed.”

I am an American Board-Certified Occupational Medicine physician, and I have worked as a tenured full professor for over 34 years in the California State University, Long Beach, which is one of the largest and most respected university systems in the United States. Second, I have published more than a dozen peer reviewed scientific articles, and have given over 50 public lectures in relation to the toxic effects of glyphosate pesticide. Except for an unsigned petition sent by some disgruntled supporters of pesticides (the contents of which were found to be completely false) my research has never been discredited in the United States, or anywhere else. In fact, I won several awards for my research, including the Research Accomplishment of the Year award from my university, the prestigious “International Award” from the Occupational Health and Safety Section of the American Public Health Association, and the Scientific Freedom and Responsibility (SFR) Award from the American Association for the Advancement of Science (an award that I shared with Prof. Channa Jayasumana). By the same token. As far as I know, Dr. Sarath Gamini does not have a single publication related to the toxicity of glyphosate pesticide. I raise this issue because one of the conditions that Dr. Sarath Gamini has stipulated, throughout his article, is that one has to be knowledgeable and competent in order to be able to make comments on any issue, within medicine or any other scientific field. Does that apply to Dr. Sarath Gamini, on the issue of Glyphosate as well?

Now, to get on to the content, throughout the paragraph on glyphosate, Dr. Sarath Gamini makes an assertion that the ban on glyphosate pesticide was made without any scientific evidence and “mostly due to political expediency” and he says, “One is not aware of any other country in the world doing so (the ban)”. These statements clearly demonstrate Dr. Sarath Gamin’s ignorance on the subject. Let me state the following facts for his knowledge, as well as that of the general public.

Hundreds of scientific research studies have linked glyphosate not only to Chronic Kidney Disease but also to many other health conditions, including autism, birth defects, inflammatory bowel syndrome and liver diseases. The World Health Organization’s International Agency for Research on Cancer reviewed the scientific evidence in a 2015 report and classified glyphosate as “probably carcinogenic to humans.” Glyphosate – brand name Roundup – is primarily associated with Non-Hodgkin Lymphoma (NHL), a cancer in the immune system. Following this determination, in October 2015, the first Roundup (Glyphosate) product liability lawsuit was filed against Monsanto in San Francisco District courts. In August 2018, a jury awarded $289 million in damages to the plaintiff – Dewayne Johnson – who is a former school groundskeeper for a California county school system when he developed NHL after spraying glyphosate regularly for several years. This amount was later reduced, during the appeals process. During this trial, evidence released by lawyers for the plaintiff tells an alarming story of ghostwriting, scientific manipulation, collusion with the United States Environmental Protection Agency (EPA), and previously undisclosed information about how the human body absorbs glyphosate. These documents provide a deeper understanding of the serious public health consequences of glyphosate, and the false advertising related to Monsanto’s conduct in marketing glyphosate.

In a second case, the jury awarded a staggering $2 billion in damages to a couple – Alva and Alberta Pilliod. In court proceedings, the Pilliods testified to using Roundup regularly, starting in 1982. The couple used the consumer version of the weedkiller, whose label lacked any warnings about covering skin or wearing protective masks. Following these successes in courts, more than 18000 cases have been filed by people who developed cancer after regularly spraying glyphosate. According to some legal reports, Bayer – the German company that bought Monsanto in 2016 – has formally submitted a $8 billion for a global settlement. In March 2020, Monsanto also agreed to pay $39.5 million as a settlement for falsely advertising Roundup is “safe” for people and pets. The settlement, which was filed in federal court in Kansas City, Missouri, resolves allegations brought by several plaintiffs who claimed Monsanto failed to warn consumers about the health risks of glyphosate.

Following the lawsuits and the expert epidemiological evidence that was presented in courts, more than 20 countries have now banned, or restricted, the use of glyphosate. Although Monsanto’s new owner, Bayer, is fighting hard to limit these restrictions, the list is growing day by day. Some of these countries include Belgium, Denmark, France, Thailand, Vietnam, Saudi Arabia, Oman, Bahrain, and Mexico. There are many cities and institutions in the U.S., including, New York, Key West, Los Angeles, the Universities of California and Miami who have now regulations to restrict the use of Glyphosate-based pesticides.

In his article, Dr. Sarath Gamini describes the revocation of the ban on glyphosate for the use in tea and coconut cultivation as a “fortunate” one. In my mind, this was one of the most “unfortunate” Cabinet decisions for several reasons: First, this policy decision was taken without much scientific advice. There was an Expert Committee that was appointed to provide advice on this matter. I was invited as an expert to testify. However, two weeks before the hearings were scheduled, the Cabinet paper was approved hastily. The main argument put forward was that there was not enough of a labour force for the removal of weeds, manually. However, many weeds have now developed resistance to glyphosate, so that one has to use manual labour to complete the process of weed removal. Second, there is no tracking and post-marketing monitoring process available in Sri Lanka to ensure that this toxic pesticide does not end up in the hands of fruit and vegetable growers and in our food. Third, the regulatory costs of protective equipment, biomonitoring and the certification of the tea and coconut products to ensure that their glyphosate levels are within acceptable limits is costly – a cost that outweighs the benefits. By now it should be clear to the reader that I have a completely opposing view on glyphosate to that of Dr. Sarath Gamini De Silva.

Furthermore, in this article Dr. Sarath Gamini describes how, over the past few years, we have seen many untruths, hypocrisy and myths being propagated by professionals misleading the ignorant public and creating social unrest and even violence. As examples, the author describes, among others, several recent incidents, including the alleged sterilization of women without consent in Kurunegala, the propagation of a questionable local medicine that was touted as a cure for Covid-19, and the issue of compulsory cremation of deaths due to Covid. I will not comment on any of these issues for two reasons: First, I was not present in the country when most of these incidents took place; Second, I have not studied the social and political dynamics, surrounding these incidents, and the policies.

Therefore, in conclusion, I would like to say this to Dr. Sarath Gamini De Silva: Now that you have talked about glyphosate, please “walk the walk” and demonstrate that you have the expertise on the subject and that you know what the “established knowledge” is. Dr. Sarath Gemini’s view of the established knowledge on glyphosate is completely antithetical to that of mine. Therefore, I would like to invite Dr. Sarath Gamini De Silva to a public debate about the toxicity of glyphosate and the appropriateness of using the pesticide in Sri Lanka agriculture.
