Overview of #290 Zach Lahn — Inside America’s Cancer‑Causing Chemical Problem

This episode of The Sean Ryan Show features Zach Lahn (introduced in the transcript as Zach Lane), a sixth‑generation Iowan, regenerative farmer, businessman, and gubernatorial candidate in Iowa. The conversation centers on agribusiness consolidation, pesticide exposure (especially glyphosate and paraquat), rural decline, captured regulatory agencies, and the political/policy responses Zach proposes at the state level. Zach combines personal family history (he restored his family farm; his father had non‑Hodgkin’s lymphoma) with policy critique and advocacy for state‑level action to protect public health, family farms, and local culture.

Guest background

  • Zach Lahn: regenerative farmer, founder of Homeplace Ventures, husband and father, son of a pastor; running for Iowa governor as an anti‑establishment/state‑focused candidate.
  • Motivation: preserve family farming culture, address what he sees as a public‑health crisis linked to agrochemicals, and resist corporate/foreign influence in Iowa.

Main topics covered

  • Agribusiness consolidation and lobbying influence
  • Right‑to‑repair and equipment control (tractor/Deere example)
  • Who owns farmland (out‑of‑state investors, hedge funds)
  • The mismatch between what Iowa grows and what Iowans eat (ethanol/feed vs food)
  • Data centers and developer tax incentives vs local benefit
  • Water pollution (nitrate runoff, tile drainage) and municipal treatment limits
  • Pesticides: glyphosate (Roundup) and paraquat — health risks, regulatory failures, litigation, and immunity concerns
  • The federal executive order invoking the Defense Production Act (DPA) to boost domestic glyphosate production and its immunity implications
  • Political strategy: focus on state power (economic nationalism / “Iowa first”), suing federal agencies, refusing certain corporate subsidies, and running a campaign free of big‑ag donors

Key facts & statistics cited

  • Average U.S. farmer age: 58.1; Iowa: 57.6.
  • Producers under 35: ~296,480 nationally (≈9%); Iowa under 35: 15,782.
  • Agribusiness lobbying (past ~10 years): ~$1.5 billion; top five companies profits ≈ $150 billion over same period.
  • Family farms lost: ~100,000 nationally (context provided); Iowa lost ~10,000 family farms over 20 years.
  • At least 25% of Iowa farmland now owned by out‑of‑state investors.
  • Iowa imports ~95% of food consumed; only ~0.03% of Iowa’s acres produce food that ends up on consumers’ plates in original form (~9,000 acres of 24 million).
  • Farmer bankruptcies increased 70% in Iowa last year (as cited).
  • Farmer suicide rate up ~50% over the last 20 years (as cited).
  • Example: Google and QTS bought ~1,400 acres south of Cedar Rapids; received ~$529 million in tax rebates to create ~30 jobs (Zach criticizes the cost per job).

Glyphosate and paraquat — technical & regulatory points

  • Distinction: pure glyphosate molecule vs glyphosate‑based herbicide formulations (GBHs). GBHs include surfactants (e.g., POEAs) that increase plant/skin penetration and are often far more toxic than the pure molecule.
  • EU vs U.S.: EU banned the U.S. formulation of Roundup/GBHs (not glyphosate molecule itself); Monsanto/Bayer reformulated products for EU markets to reduce some toxicity.
  • Health concerns: links to non‑Hodgkin’s lymphoma (numerous lawsuits/jury verdicts), genotoxicity, potential bone marrow accumulation (glyphosate is a chelator that binds calcium), and persistent residues in people’s urine even after dietary changes.
  • Paraquat: extremely toxic, used in research to induce Parkinson’s in animals; banned in many countries and even in the country where a major manufacturer is based.
  • Testing/regulatory gaps: EPA historically requires testing of the active molecule, not always the full commercial formulation; tolerance limits for residues can be raised by industry petition (example: oats tolerance increased dramatically to accommodate desiccation practices).
  • Litigation: Bayer/Monsanto has paid large settlements and lost jury trials; internal documents (“Monsanto files”) show corporate knowledge and regulatory capture in Zach’s view.

Policy developments & concerns

  • Feb 18 executive order invoking the Defense Production Act to boost domestic glyphosate production: Zach argues it effectively grants immunity (Section 707 language, broad interpretation) and shifts liability onto taxpayers. He and others (including EWG’s Ken Cook) view this as dangerous.
  • State remedies Zach advocates:
    • Use state authority (Chevron reversal precedent) to sue federal agencies and reclaim regulatory control.
    • Refuse refundable tax credits to foreign/state‑owned multinationals (cited: Syngenta—alleged Chinese state ownership—and $7.5M in refundable credits from Iowa).
    • Stop or renegotiate massive tax abatements that deliver little local employment value (data center example).
    • Protect family farms and incentivize local food production for schools.
    • Push for transparency in legislation (e.g., disclose who drafted provisions inserted into bills).
    • Oppose immunity laws for pesticide manufacturers and push for labeling/warning requirements.

Personal stories & motivation

  • Family farm history: ancestors who emigrated, Civil War service, multigenerational homestead sold in 2005 and bought back by Zach in 2014; restored farmhouse board‑by‑board using family photos.
  • Personal health connection: Zach’s father (crop consultant) diagnosed with non‑Hodgkin’s lymphoma — a motivating factor in Zach’s pesticide activism.
  • Faith and stewardship: ties stewardship of land and community values to his Christian faith and campaign mission.

Notable quotes / lines of argument

  • “Safe products don’t need immunity.” — used to argue against liability shields for agrochemical companies.
  • “Silence is a lie.” (Jordan Peterson cited) — Zach frames speaking out as a moral imperative in politics.
  • Recurrent theme: regulatory capture — “these companies are not your friends,” and agencies have been influenced by industry lobbying.

Main takeaways

  • Zach presents glyphosate and other agrochemicals as a serious public‑health threat exacerbated by industry tactics (reformulations, lobbying, and legal maneuvers to avoid liability).
  • He argues federal institutions are deeply captured and that meaningful change should be pursued at the state level: suing federal agencies, refusing certain corporate incentives, and putting “Iowa first.”
  • The conversation links environmental contamination, rural economic decline, loss of family farms, and rising cancer rates into a single policy/ethical crisis.
  • Zach’s candidacy is framed as grassroots/state‑level resistance to corporate capture and cultural erosion, not as a conventional partisan run for D.C.

Suggested actions (from themes in the episode)

  • For voters: prioritize state races and gubernatorial policy platforms — state government can act on many of the issues discussed.
  • For communities: demand transparency (who wrote specific legislative provisions), oppose undue tax breaks to foreign/state‑owned companies, and press local officials on water quality and local food sourcing.
  • For health & environmental advocates: support independent testing of commercial formulations (not only active ingredients), push for full disclosure of tolerances and historical industry petitions, and oppose immunity provisions that shield manufacturers from product liability.
  • For researchers/journalists: continue investigating internal corporate documents, regulatory decision pathways, and local incidence maps correlating pesticide use and cancer outcomes.

Bottom line

This episode is a mix of personal testimony, data‑driven claims, policy critique, and campaign messaging. Zach Lahn positions agrochemical exposure (primarily glyphosate and paraquat) and corporate/regulatory capture as central threats to Iowa’s health, communities, and food sovereignty. He advocates state‑level legal and policy responses, greater transparency, and a cultural/political reframing to prioritize local well‑being over corporate and foreign shareholder interests.
