Forever Chemicals (PFAS) Found in Hershey’s Chocolate

Hershey’s Sweet Deception

TL;DR

  • The Accusation: A class-action lawsuit (Case No. 1:24-cv-01868-CCC) alleges that The Hershey Company sells iconic candies like Reese’s Peanut Butter Cups and Hershey’s Kisses in wrappers contaminated with dangerous levels of PFAS, also known as “forever chemicals.”
  • The Misconduct: Hershey markets its products as safe and high-quality. The lawsuit claims this is fraudulent, as the company fails to disclose that its packaging contains toxic, carcinogenic substances that persist in the human body and the environment.
  • The Stakes: Consumers paid a premium for products they believed were safe. The lawsuit seeks economic damages for this deception and demands Hershey stop using contaminated packaging. The FDA banned PFAS in food packaging in February 2024, yet independent testing shows the chemicals remain.

The raw data exposing which of your favorite candies are contaminated is in The Contamination Matrix below.

An American Icon, A Hidden Poison

The Hershey Company built an empire on nostalgia and trust. Its products are fixtures of childhood holidays and daily treats. The company’s marketing relies on this image, promising quality and safety so consumers can “rest assured they can enjoy Hershey’s products without any risks.” A new class-action lawsuit filed in the U.S. District Court for the Middle District of Pennsylvania alleges this promise is a calculated lie.

The complaint, brought by plaintiff Jonathan Parish on behalf of millions of consumers, asserts that the wrappers on products like Hershey Milk Chocolate Bars, Reese’s Pieces, and Almond Joy contain heightened levels of per- and polyfluoroalkyl substances (PFAS). These are synthetic “forever chemicals” that do not break down in nature or the human body. They accumulate over time and are linked by the CDC to cancer, liver damage, decreased fertility, and thyroid disease.

The Non-Financial Ledger

The harm here is measured in more than the price of a candy bar. It is measured in the corrosion of trust. Every time a parent gives their child a Hershey’s Kiss, they are acting on a belief in the safety of that product, a belief cultivated by decades of branding. The lawsuit alleges this act of trust is being betrayed at a sub-cellular level.

“Plaintiff’s purchase and consumption of Confectionery Products has resulted in Plaintiff’s suffering physical impact in the form of being exposed to a non-bargained for agent with potent mutagenic properties that operates at the cellular and sub-cellular levels…”

This is the core of the deception. Consumers are not just buying chocolate; they are unknowingly buying exposure. The lawsuit argues that had people known the truth, they never would have purchased these products, or at least not on the same terms. The cost is a loss of bodily autonomy and peace of mind, a tax paid by the public for corporate negligence.

Societal Impact Mapping

Public Health Catastrophe

PFAS are toxic even at very low levels. The Centers for Disease Control and Prevention (CDC) links them to a host of devastating health effects, including cancer, liver damage, and immune system disruption. Because these chemicals are “forever,” every exposure adds to the body’s cumulative burden. By packaging its products in contaminated materials, Hershey is contributing to a slow-motion public health crisis, one bite at a time.

Environmental Degradation

The “forever chemical” moniker is literal. When a candy wrapper is thrown away, the PFAS within it does not disappear. It leaches into soil and groundwater, contaminating ecosystems for generations. The lawsuit notes that the use of PFAS is entirely unnecessary for this type of packaging, making the resulting environmental pollution a direct consequence of corporate indifference.

Economic Inequality

The economic injury, as outlined in the lawsuit, is clear: consumers paid for a safe, premium product and received a defective, dangerous one. This transfers wealth from the working class to corporate shareholders. The long-term costs of healthcare and environmental cleanup associated with PFAS contamination will be borne by the public, while Hershey continues to profit from the products causing the harm.

The Contamination Metric

33.2 mg/kg

Highest Fluorine Level Detected in Almond Joy/Mounds Wrappers

This level of contamination is unnecessary, unsafe, and comes from chemicals now banned by the FDA for use in food packaging.

The Contamination Matrix

Independent third-party testing, cited in the lawsuit, revealed the presence of specific PFAS compounds and total fluorine in the wrappers of many popular Hershey products. The data shows a widespread contamination problem. While KitKat Bar wrappers tested low for specific compounds, they still contained measurable levels of fluorine, a key indicator of PFAS.

Total Fluorine Levels (mg/kg) in Wrappers Almond Joy Reese’s Cups Reese’s Pieces Hershey Bar Kisses Cookies n’ Cream KitKat Bar 0 10 20 30 40 Fluorine (mg/kg) 33.2 26.7 23.4 17.2 15.0 11.7 12.0

What Now?

This legal action is a critical first step. Accountability does not end in the courtroom. Real change requires sustained pressure on the corporate officers and regulatory bodies that allow this to happen.

Corporate Watchlist

  • The Hershey Company Board of Directors: Ultimately responsible for corporate policy and risk management.
  • Chief Quality & Compliance Officer: Directly oversees the safety and standards of products and their packaging.
  • Head of Supply Chain Management: Responsible for sourcing the materials, including the contaminated wrappers, used in production.

Regulatory Watchlist

  • Food and Drug Administration (FDA): While they have banned PFAS in food packaging, enforcement and testing of existing products on shelves is crucial.
  • Environmental Protection Agency (EPA): Responsible for addressing the environmental contamination caused by PFAS from discarded packaging.

The Path Forward

Support class-action lawsuits like this one. Demand that retailers pull contaminated products from their shelves. Organize locally to raise awareness about corporate negligence and advocate for stricter regulations with real teeth. True power lies in mutual aid and collective action against the corporations that prioritize profit over public health.
