Glyphosate, GMOs, and Growing Food Sustainably, feat. Chuck Benbrook

Nicole Shanahan hosts Chuck Benbrook, an American agricultural economist, researcher, and organic agriculture advocate with decades of experience in pesticide law and regulation. Benbrook has served as an expert witness in multiple glyphosate litigations and worked extensively on national pesticide policy.

Key Takeaways
  1. 01

    "It's very difficult to avoid glyphosate completely through the American diet" - Chuck Benbrook on ubiquitous pesticide exposure

  2. 02

    Bayer has spent over $20 billion dealing with glyphosate litigation, nearly losing the $63 billion Monsanto acquisition value

    European Roundup formulations are safer than US versions - EU banned POEA surfactants in 2017 while US continues using them

  4. 04

    Pre-harvest crop desiccation accounts for 95% of dietary glyphosate exposure but only 2-3% of total usage

  5. 05

    Glyphosate causes DNA mutations in bone marrow stem cells, leading to non-Hodgkin's lymphoma and leukemia

  6. 06

    "Most Roundup formulations don't even say to wear gloves when you're spraying it" - Chuck on inadequate safety warnings

Nicole Shanahan hosts Chuck Benbrook, an American agricultural economist, researcher, and organic agriculture advocate with decades of experience in pesticide law and regulation. Benbrook has served as an expert witness in multiple glyphosate litigations and worked extensively on national pesticide policy.

The conversation centers on glyphosate, America's most widely used pesticide, examining its health impacts, regulatory failures, and the corporate strategies surrounding its continued use. Benbrook draws parallels between glyphosate disclosure issues and mRNA vaccine transparency concerns, while exploring Bayer's acquisition of Monsanto and the ongoing litigation crisis.

Key topics include the mechanisms by which glyphosate causes cancer, the stark differences between European and American formulations, the pesticide industry's state-by-state preemption campaign, and the broader implications for American agriculture and public health. The discussion also touches on reproductive health impacts and references The Handmaid's Tale as a potential warning about fertility decline from chemical exposures.

The Glyphosate Ubiquity Problem in American Food

Despite organic food availability, "it's very difficult to avoid glyphosate completely through the American diet" due to its ubiquitous presence in the environment and food supply.

Families eating all-organic diets still show high glyphosate levels in urine tests, indicating exposure through water, air, or cross-contamination from widespread agricultural use.

Pre-harvest crop desiccation - spraying Roundup before harvest to dry crops - accounts for "95% of the exposure across 330 million Americans" while representing only 2-3% of total glyphosate use.

European farmers achieve similar corn and soybean productivity without genetically engineered seeds or high-volume Roundup spraying, proving alternatives exist.

How Glyphosate Triggers Blood Cancers Through DNA Damage

Glyphosate moves through skin into bloodstream via surfactants designed to penetrate plant epidermis, with "about 10% of cardiac output at all times being pumped through bone marrow."

In bone marrow, glyphosate contacts hematopoietic stem cells during DNA replication and differentiation, causing mutations that trigger abnormal cell growth leading to non-Hodgkin's lymphoma.

New research links glyphosate to leukemia in addition to non-Hodgkin's lymphoma, with evidence suggesting other blood cancers may also be connected to exposure.

"It takes a lot of glyphosate and a lot of Roundup to make people sick" - most litigation plaintiffs were heavily exposed for 10-30 years through direct application.

Bayer's $20 Billion Litigation Crisis and European Safety Standards

Bayer has spent over $20 billion on glyphosate litigation costs, with the company's market cap nearly losing the entire $63 billion Monsanto acquisition value within six months of the first California trials.

"They didn't buy Monsanto because they wanted to sell Roundup. They bought Monsanto because of the genetically engineered seeds and the intellectual property" - Chuck on Bayer's acquisition strategy.

European Union forced safer Roundup formulations in 2017 by banning POEA surfactants, while Monsanto chose not to implement the same safety improvements worldwide despite internal discussions.

Bayer may eventually sell its agricultural division and create a shell company with $20-30 billion to handle remaining liability, effectively capping future victim compensation.

The Preemption Campaign to Block Failure-to-Warn Lawsuits

Georgia and North Dakota passed preemption laws preventing glyphosate failure-to-warn claims in state courts, with the pesticide industry targeting 11 states total this year.

"Most Roundup formulations that both farmers buy and homeowners buy, it doesn't even say to wear gloves when you're spraying it" due to Monsanto's marketing strategy emphasizing safety.

Current federal law makes pesticide manufacturers responsible for label warnings, not EPA, based on Supreme Court precedent from Texas farmers harmed by Dow AgroSciences herbicide.

Preemption would give companies "a stay out of court forever card" and remove incentives for developing safer formulations or adequate warnings.

Reproductive Health Crisis and Population Decline Warnings

Declining sperm quality trends in developed countries could make "live births become rare" within 20-30 years if continued, making The Handmaid's Tale "maybe not just science fiction."

The 1996 Food Quality Protection Act mandated extra safety layers for pregnant women, infants, and children, but "the industry fought back" and prevented meaningful implementation.

"America could have the safest, most delicious, nutritious food supply in the world" without new science - it's "just a question of priorities about the kind of system that we're willing to support."

Pesticide exposures particularly harm reproductive health because "the whole human reproductive process is so complicated and elegant and vulnerable to chemical insult."
