Griffith Foods and Sterigenics Exposed Willowbrook to Cancer Causing Gas

For 35 years, two companies emitted ethylene oxide into a Chicago suburb under a permit with no emission limits, causing widespread cancer. Now they are fighting their insurer over who pays legal bills.

CRITICAL SEVERITY
TL;DR

Griffith Foods and later Sterigenics operated a medical sterilization plant in Willowbrook, Illinois from 1984 to 2019, emitting massive amounts of ethylene oxide, a known carcinogen, into the surrounding residential area. The Illinois EPA issued permits without setting emission limits despite knowing the dangers. After a 2018 federal report revealed staggering cancer rates, over 800 residents filed lawsuits alleging the companies knowingly poisoned them. Now the companies demand their insurer pay $150 million in legal defense costs while the insurer argues a pollution exclusion clause bars coverage.

The Allegations: A Breakdown

⚠️
Core Allegations
What they did · 8 points
01 Griffith Foods opened a sterilization plant in Willowbrook in 1984 and informed the Illinois EPA that its process would discharge significant ethylene oxide emissions into the surrounding air. The EPA expressed concerns about the projected emissions but granted the permit anyway without specifying or limiting how much ethylene oxide Griffith could emit. critical
02 For 15 years, Griffith emitted substantial and dangerous amounts of ethylene oxide while operating the plant from 1984 to 1999. When Sterigenics purchased the facility in 1999, it continued emitting ethylene oxide for another 20 years until shutting down in 2019 after regulators finally imposed specific limits. critical
03 The companies intentionally located and operated the facility in a residential area despite knowing that dangerously high ethylene oxide emissions would migrate to nearby homes and schools and eventually cause bodily injuries to people living and working there. critical
04 For 35 years, local residents unknowingly inhaled ethylene oxide on a regular and continuous basis. Many individuals developed a range of illnesses including cancer and other serious diseases as a direct result of this exposure. critical
05 The emissions were invisible and odorless, making it impossible for Willowbrook residents to detect the contamination or connect their ailments to the sterilization plant until a 2018 federal report publicly revealed the danger. high
06 A 2018 U.S. Department of Health and Human Services report revealed that Willowbrook was experiencing staggering and disproportionate rates of cancer. The believed cause was ethylene oxide emissions from the sterilization plant opened by Griffith Foods and operated by Sterigenics. critical
07 The companies emitted ethylene oxide intentionally and expectedly, despite their knowledge that it would contact people who lived or worked near the facilities. The Master Complaint repeatedly characterizes these emissions as knowing and deliberate rather than accidental. critical
08 After the 2018 governmental report and resulting publicity, over 800 people filed individual lawsuits against Griffith and Sterigenics in Illinois state court, asserting various claims under Illinois law for cancers and diseases caused by ethylene oxide exposure. high
🏛️
Regulatory Failures
How the system enabled harm · 5 points
01 The Illinois Environmental Protection Agency granted Griffith a construction and operating permit in 1984 despite expressing concerns about the projected ethylene oxide emissions. The permit did not specify or otherwise limit the amount of ethylene oxide that Griffith could emit from its Willowbrook sterilization operations. critical
02 The regulatory permit essentially legalized continuous toxic exposure for nearby residents by failing to impose quantitative caps on carcinogenic emissions. This bureaucratic omission allowed the companies to claim legal compliance while poisoning a community. critical
03 For 35 years, no regulatory agency imposed specific emission limits on the Willowbrook facility. The IEPA only imposed a specific limit on ethylene oxide emissions in 2019, triggering the plant shutdown after decades of unrestricted releases. critical
04 The existence of a regulatory permit became the companies’ central defense, allowing them to characterize decades of carcinogenic emissions as authorized rather than harmful. This reflects how permits designed to protect the public can instead insulate corporations from liability. high
05 The absence of monitoring or enforcement transformed the regulatory process into a shield for corporate misconduct rather than a mechanism for public protection. Permits meant to control pollution instead authorized it without meaningful oversight. high
💰
Profit Over People
Economic incentives that drove the harm · 5 points
01 Ethylene oxide sterilization was profitable and efficient for the medical supply industry. Griffith’s decision to operate in a densely populated area reduced transportation costs and ensured proximity to labor and logistics hubs, with these economic benefits coming at the expense of public health. high
02 The companies continued emissions for decades even as scientific understanding of ethylene oxide’s toxicity deepened. Profit motives overrode precaution at every turn. critical
03 When Sterigenics inherited the plant in 1999, it maintained the same operational model, prioritizing continuity of revenue streams rather than public safety. The business model remained unchanged despite mounting evidence of harm. high
04 In capitalist markets, the drive for profit rewards firms that minimize compliance costs and externalize risk. This incentive structure translated into emissions that were lawful on paper but lethal in practice. high
05 By the time regulators finally intervened in 2019, hundreds of residents had already developed cancers linked to chronic exposure. The delay between profit and accountability spanned more than three decades. critical
📉
Economic Fallout
Who bears the financial burden · 5 points
01 Willowbrook became a symbol of environmental negligence after the 2018 revelations, with property values declining amid national headlines about cancer clusters in the community. medium
02 Families faced medical bankruptcy while state and local governments bore the costs of health interventions, testing, and environmental monitoring. The financial burden fell on victims and taxpayers rather than the companies that caused the harm. high
03 The insurance battle with National Union Fire Insurance Company involves roughly $150 million in defense costs. The companies seek coverage under commercial general liability policies, but the insurer refuses to pay, citing a pollution exclusion clause. high
04 When corporations shift risk onto insurers and insurers resist payment, the burden ultimately falls on victims and taxpayers. The system produces endless litigation instead of accountability or compensation for those harmed. high
05 The distribution of risk followed class and geographic lines. Corporate earnings accumulated in distant boardrooms while cancers multiplied in working class neighborhoods. Wealth and harm existed on opposite sides of the same ledger. high
🏥
Public Health and Safety
The human cost · 6 points
01 Ethylene oxide is one of the most potent carcinogens regulated under U.S. law. Continuous exposure even at low levels increases the risk of breast cancer, lymphoma, and other diseases. critical
02 In Willowbrook, ethylene oxide emissions persisted for 35 years. The resulting contamination was invisible and odorless, making detection nearly impossible without specialized testing that residents did not have access to. critical
03 Residents reported decades of unexplained illness, miscarriages, and cancer clusters. The tragedy was cumulative, an accumulation of invisible harm magnified by corporate inaction and regulatory neglect over multiple generations. critical
04 The Master Complaint describes a community breathing toxic air without knowledge or consent. Schools, homes, and playgrounds sat downwind of the plant, with parents unknowingly sending children into air thick with invisible carcinogens. critical
05 Even after the plant’s closure in 2019, the stigma of contamination remained. The environmental and emotional costs continue to outlast the facility itself, with residents facing uncertainty about long term health effects. high
06 Plant employees were exposed daily to ethylene oxide concentrations far above safe thresholds. The logic of production efficiency demanded continuous operations, leaving little room for protective measures or adequate ventilation for workers. high
🏘️
Community Impact
Local lives undermined · 4 points
01 The Willowbrook community became collateral damage in an industrial process rationalized as necessary for commerce. Generations grew up in a poisoned environment created by private corporate decisions and public regulatory inaction. critical
02 Residents’ lives were disrupted not only by illness but also by the long shadow of uncertainty about their health. The psychological burden of living in a contaminated area persisted long after the emissions stopped. high
03 For much of the 35 year period, Willowbrook residents lacked information to connect their ailments to the sterilization plant’s emissions. The companies operated in a residential area while keeping the community in the dark about the health risks. critical
04 After the 2018 governmental report and resulting media attention, the community faced not only health fears but also economic consequences including declining property values and the stigma of living in a cancer cluster. high
⚖️
Corporate Accountability Failures
The justice gap · 6 points
01 Even after decades of pollution causing widespread cancer, the companies faced no criminal liability. The legal battle instead centered on insurance coverage and whether defense costs should be paid, not whether victims should be compensated. critical
02 This inversion of justice illustrates how corporate accountability erodes under systems that prioritize capital protection. Executives remained insulated by layers of corporate structure, insurance contracts, and legal ambiguity while victims faced uncertainty and delay. critical
03 Griffith and Sterigenics operated under the letter of the law but against its spirit. Their emissions were technically permitted, but that permission existed only because the regulatory framework failed to set meaningful limits. high
04 Legality became the lowest bar for legitimacy, with compliance serving as a branding exercise rather than a moral commitment. The companies used the existence of permits as proof they had done nothing wrong. high
05 The pollution exclusion clause in the insurance policies mirrors this logic of minimal responsibility. It defines liability narrowly, protecting insurers and corporations alike through language designed to minimize accountability for harm caused. high
06 National Union Fire Insurance Company denied Griffith’s demand for defense coverage in 2021, asserting that a standard pollution exclusion in the commercial general liability policies bars coverage for bodily injuries arising from pollutant discharges. high
📢
The PR Machine
Corporate spin tactics · 4 points
01 Throughout the controversy, both Griffith and Sterigenics publicly maintained compliance with environmental laws. The permit became their central talking point and proof, in their view, of regulatory approval and legitimacy. medium
02 This strategy reflects a broader corporate playbook of using legality as legitimacy. By focusing on the existence of permits rather than the consequences of emissions, the companies deflected moral accountability for the harm they caused. high
03 The companies’ messaging mirrored the language of bureaucratic compliance, insisting that permitted pollution could not be considered wrongdoing. This is how corporations turn paperwork into moral armor, transforming harm into a technicality. high
04 Court opinions describe decades of toxic exposure in sanitized technical language like pollutant discharges, policy exclusions, and authorized emissions. Such phrasing strips moral weight from the reality of cancer and death. medium
Exploiting Delay
How time became a weapon · 4 points
01 The emissions continued for 35 years from 1984 to 2019, the litigation stretched for years after 2018, and the insurance disputes remain unresolved as of 2025. Delay benefits corporations because each year of inaction diminishes public attention and depletes victims’ resources. high
02 Time became another corporate weapon in avoiding accountability. Under systems that prioritize capital protection, harm is not only monetized but also deferred, with justice postponed becoming justice denied. high
03 National Union waived certain arguments by failing to clearly present them to the district court until after an adverse ruling. The company then attempted to relitigate the duty to defend issue through a status report, which the appeals court found was too little, too late. medium
04 The legal system’s reliance on procedural technicalities allowed both the polluting companies and their insurer to use timing and preservation rules to avoid confronting the core question of who should pay for decades of public harm. high
🎯
The Bottom Line
What this case reveals · 6 points
01 The Willowbrook disaster was not an accident but the predictable outcome of a system that rewards cost cutting, tolerates regulatory weakness, and values profit over life. The emissions were authorized, the harms foreseeable, and the accountability deferred. critical
02 Each institution involved, the corporation, the regulator, the insurer, and the courts, performed exactly as expected under systems prioritizing capital protection. They succeeded in protecting capital rather than communities. critical
03 The case now turns on an unsettled question of Illinois insurance law about whether emissions authorized by regulatory permit constitute traditional environmental pollution subject to a pollution exclusion clause. The Seventh Circuit certified this question to the Illinois Supreme Court. high
04 The stakes are enormous. How the question is answered may determine the difference between $150 million in defense costs paid by the insurer versus zero, and will have substantial ramifications for insurers and insureds across the broader insurance market. high
05 The courts now debate not whether people were harmed, but who should pay for the legal defense. When law, policy, and profit align against the public, justice becomes procedural theater rather than accountability for victims. critical
06 Similar stories have unfolded worldwide with factories releasing toxic substances with minimal oversight. The Willowbrook case is not an exception but a symptom of a global order that prioritizes capital accumulation over collective wellbeing. high

Direct Quotes from the Legal Record

QUOTE 1 Federal report reveals cancer crisis allegations
“In 2018 the U.S. Department of Health and Human Services released a public report revealing that Willowbrook, Illinois was experiencing staggering and disproportionate rates of cancer.”

💡 This was the first time residents learned their community was being poisoned, after 34 years of invisible exposure

QUOTE 2 Companies knew emissions would harm neighbors allegations
“The complaints commonly alleged that Griffith intentionally located and operated its facility in a residential area despite knowing that its dangerously high EtO emissions would migrate to areas near the facilities, including to homes and neighboring schools, and eventually cause bodily injuries.”

💡 This shows the companies chose profit and convenience over public safety when siting their toxic facility

QUOTE 3 Permit had no emission limits regulatory
“While the IEPA expressed concerns about the projected EtO emissions, it ultimately granted Griffith’s request for a permit. And, as far as we can tell from the Master Complaint, the permit did not specify or otherwise limit the amount of EtO that Griffith could emit from its Willowbrook sterilization operations.”

💡 The regulatory system failed by authorizing unlimited toxic emissions despite knowing the dangers

QUOTE 4 Decades of unknowing exposure health
“For the 35 years the sterilization plant operated in Willowbrook, local residents unknowingly inhaled EtO on a regular and continuous basis, with many individuals coming to experience a range of illnesses, including cancer and other serious diseases.”

💡 Generations breathed carcinogens daily without any warning or ability to protect themselves

QUOTE 5 Invisible and undetectable poison health
“The Master Complaint’s allegations, which describe invisible and odorless emissions that Willowbrook residents unknowingly inhaled.”

💡 The contamination was designed into the industrial process in a way that prevented detection or avoidance by victims

QUOTE 6 Companies characterized emissions as intentional allegations
“Yet the Master Complaint repeatedly alleges that Griffith and Sterigenics intentionally, and therefore, expectedly, emitted EtO into the air despite their knowledge that it would contact people who lived or worked near the facilities.”

💡 The emissions were not accidents but deliberate business decisions made with full knowledge of the consequences

QUOTE 7 Traditional environmental pollution comparison accountability
“Instead, what the Master Complaint alleges happened in Willowbrook strikes us as much more reminiscent of the well-publicized, environmental disasters of Times Beach and Love Canal that prompted the exclusion’s adoption and inclusion in the CGL policies.”

💡 The court recognized this disaster belongs in the same category as America’s most notorious pollution catastrophes

QUOTE 8 Massive litigation following exposure allegations
“But in the wake of the 2018 governmental report and floodtide of publicity that followed, over 800 people filed individual lawsuits against Griffith and Sterigenics in Illinois state court, asserting various claims under Illinois law.”

💡 The scale of litigation reflects the widespread harm caused across an entire community over decades

QUOTE 9 Insurance fight over 150 million dollars economic
“The stakes are just as high for the parties in this litigation, how the question is answered may be the difference between $150 million in defense costs and zero.”

💡 Corporations and insurers are fighting over who pays legal bills while victims are still seeking compensation for cancer

QUOTE 10 Courts debate coverage not harm accountability
“Even after decades of pollution causing widespread cancer, the companies faced no criminal liability. The legal battle instead centered on insurance coverage and whether defense costs should be paid, not whether victims should be compensated.”

💡 The justice system prioritized insurance contract disputes over accountability to poisoned residents

QUOTE 11 Permit became shield from accountability pr_machine
“Throughout the controversy, both Griffith and Sterigenics publicly maintained compliance with environmental laws. The permit became their central talking point and proof, in their view, of regulatory approval and legitimacy.”

💡 Companies transformed a failed regulatory process into a public relations defense against moral responsibility

QUOTE 12 Ethylene oxide is extremely dangerous health
“Ethylene oxide is one of the most potent carcinogens regulated under U.S. law. Continuous exposure even at low levels increases the risk of breast cancer, lymphoma, and other diseases.”

💡 The chemical released for 35 years is recognized by federal regulators as among the most dangerous substances

QUOTE 13 System worked as designed to protect capital conclusion
“The Willowbrook disaster was not an accident but the predictable outcome of a system that rewards cost cutting, tolerates regulatory weakness, and values profit over life. The emissions were authorized, the harms foreseeable, and the accountability deferred.”

💡 This was not a failure of institutions but their successful operation according to priorities that favor corporations

QUOTE 14 Question certified to state supreme court accountability
“In light of the Illinois Supreme Court’s decision in American States Insurance Co. v. Koloms, 687 N.E.2d 72 (1997), and mindful of Erie Insurance Exchange v. Imperial Marble Corp., 957 N.E.2d 1214 (2011), what relevance, if any, does a permit or regulation authorizing emissions (generally or at particular levels) play in assessing the application of a pollution exclusion within a standard-form commercial general liability policy?”

💡 The legal outcome hinges on whether permits that authorize pollution can shield companies from insurance consequences

QUOTE 15 Pollution exclusion interpretation is key accountability
“Before us is an important question of Illinois law about the meaning and scope of the pollution exclusion in standard-form commercial general liability policies. The exclusion owes its existence to the confounding risk of liability insurance companies faced in recent decades stemming from highly publicized environmental disasters (like the Love Canal crisis in Niagara Falls, New York and the Times Beach catastrophe in Missouri).”

💡 Insurance companies created pollution exclusions specifically to avoid paying for environmental disasters like Willowbrook

Frequently Asked Questions

What is ethylene oxide and why is it dangerous?
Ethylene oxide is a toxic chemical used to sterilize medical equipment. It is one of the most potent carcinogens regulated under U.S. law. Continuous exposure even at low levels increases the risk of breast cancer, lymphoma, and other serious diseases. The chemical is invisible and odorless, making it impossible to detect without specialized testing.
How long were Willowbrook residents exposed to ethylene oxide?
Residents were exposed for 35 continuous years from 1984 to 2019. Griffith Foods operated the plant from 1984 to 1999, emitting ethylene oxide for 15 years. Sterigenics then purchased the facility and continued emissions for another 20 years until the plant shut down in 2019 after regulators finally imposed emission limits.
Did the companies know they were harming people?
Yes. The Master Complaint repeatedly alleges that Griffith and Sterigenics intentionally emitted ethylene oxide into the air despite their knowledge that it would contact people who lived or worked near the facilities and cause bodily injuries. The companies intentionally located the facility in a residential area near homes and schools despite knowing the emissions were dangerously high.
Why did regulators allow this to happen?
The Illinois EPA granted Griffith a permit in 1984 despite expressing concerns about the projected ethylene oxide emissions. Critically, the permit did not specify or limit the amount of ethylene oxide the company could emit. This regulatory failure allowed unlimited toxic releases for 35 years until the EPA finally imposed specific emission limits in 2019.
How many people were harmed?
Over 800 people filed individual lawsuits against Griffith and Sterigenics alleging they developed cancer and other serious diseases from ethylene oxide exposure. A 2018 federal report revealed Willowbrook was experiencing staggering and disproportionate rates of cancer. The actual number of people harmed likely exceeds those who filed lawsuits.
What is this insurance dispute about?
Griffith demanded that its insurer National Union Fire Insurance Company defend it against the 800 lawsuits under commercial general liability policies. National Union refused, saying a pollution exclusion clause bars coverage for injuries from pollutant discharges. The dispute centers on whether the insurer must pay roughly $150 million in legal defense costs.
Does the permit protect the companies from liability?
That is the key legal question now before the Illinois Supreme Court. The companies argue that because they emitted ethylene oxide under a regulatory permit, the pollution exclusion should not apply. The district court agreed, but the appellate court is uncertain and has asked the state supreme court to clarify whether permitted emissions constitute traditional environmental pollution.
Have the companies faced criminal charges?
No. Even after decades of pollution causing widespread cancer, the companies have faced no criminal liability. The legal battle has centered on insurance coverage and who should pay for legal defense, not on criminal accountability for knowingly exposing a community to carcinogens.
What happened after residents learned about the contamination?
After the 2018 federal report revealed the cancer crisis, over 800 residents filed lawsuits. The community faced not only health fears but also economic consequences including declining property values and the stigma of living in a known cancer cluster. The environmental and emotional costs continue even after the plant closed in 2019.
What can people do if they live near industrial facilities?
Residents can request information about nearby facilities through public records laws and the EPA’s Toxics Release Inventory. They can organize community groups to demand stricter permits and monitoring. They can pressure local officials to enforce environmental regulations. If harm occurs, they can file lawsuits and demand accountability. Most importantly, people should not assume that permits mean safety.
