If you think your liver is safe because you don’t drink or carry extra pounds, brace yourself—a household solvent hiding in plain sight may be quietly tripling your risk of irreversible liver scarring.
Story Snapshot
- PCE, a common cleaning chemical, triples the risk of liver fibrosis—even if you lead a healthy lifestyle.
- Dry cleaning, household products, and even tap water are stealthy sources of exposure.
- Major regulatory efforts lag behind science, leaving millions potentially at risk.
- Experts urge immediate awareness and screening before silent liver damage sets in.
PCE: The Silent Threat Lurking in Your Closet and Kitchen
For decades, PCE—tetrachloroethylene—has been the backbone of the dry cleaning industry and a staple in everything from spot removers to metal polish. Most Americans have brushed up against this chemical countless times, whether picking up pressed shirts or scrubbing a stubborn stain from the counter. Few suspect this invisible residue could quietly scar the organ that keeps their body’s chemistry in balance. Now, for the first time, a large-scale human study has delivered a jolt: exposure to PCE can triple your risk of developing liver fibrosis, a precursor to life-threatening liver failure, even without the usual suspects like alcohol or obesity in play.

Researchers from Keck Medicine of USC analyzed blood samples from thousands of American adults, spanning data collected between 2017 and 2020. Their findings, published November 12, 2025, in Liver International, are not just statistically significant—they’re paradigm-shifting. The more PCE in the bloodstream, the greater the liver damage. This dose-response relationship flips the script on who should be worried about liver disease, and it’s not just heavy drinkers or the overweight.

How Everyday Exposure Becomes a Hidden Epidemic
PCE’s journey from industrial workhorse to household hazard traces back over a century. Used since the early 1900s, it’s classified as a probable carcinogen by international authorities and has long been linked to cancers and nerve damage. Yet, despite mounting evidence of harm, PCE lingers in the air of dry cleaning shops, seeps into groundwater from improper disposal, and evaporates from the very products lining supermarket shelves. Even as the EPA works to phase out its use in dry cleaning, loopholes and lagging enforcement leave the chemical freely circulating in other consumer goods and in drinking water in some communities.
Who’s Sounding the Alarm—and Who’s Dragging Their Feet?
Dr. Brian P. Lee, lead author and liver specialist at Keck Medicine, puts it bluntly: “Exposure to PCE may be the reason why one person develops liver disease while someone with the exact same health and demographic profile does not.” For years, unexplained cases of liver scarring—where patients had no history of drinking, obesity, or hepatitis—have troubled doctors. Now, environmental toxins like PCE are emerging as the missing piece of the puzzle. The implication is sobering: millions could be at risk and not even know it. Regulatory agencies like the EPA hold the power to act, but industry resistance and slow-moving policy have left many gaps.
What Comes Next: Screening, Scrutiny, and a Call for Change
The immediate aftermath of the study’s release has been a flurry of media coverage and calls from experts for increased public screening. Doctors now urge anyone with significant PCE exposure—dry cleaning workers, frequent customers, those using certain household products, or people living near contaminated water sources—to get checked for liver damage, even if their lifestyle seems healthy. Long-term, the findings could reshape regulations, accelerate chemical phaseouts, and force a reckoning over the true cost of “clean.” For now, the message is clear: the greatest threats to your health may not come from choices you make, but from chemicals you never chose at all.
