The food system’s synthetic chemicals, including pesticides, plastic additives, PFAS (“forever chemicals”), and other industrial compounds, are increasingly being linked to severe health problems and staggering economic costs around the world. A landmark global assessment has estimated that the health burden attributable to these synthetic chemicals may be as high as $2.2 trillion annually, driven by rising rates of cancer, infertility, neurodevelopmental disorders, and other chronic diseases. This article breaks down what the evidence shows, why it matters, and what researchers and policymakers are calling for now.
What the Latest Evidence Reveals: A Hidden Cost of Modern Diets
A major international report released in 2025 found that chemicals embedded deep into modern food systems, from pesticides used on crops to plastic additives in food packaging, are contributing to a massive global health burden. The analysis concluded that exposure to phthalates, bisphenols, pesticides, and PFAS “forever chemicals” may cost up to $2.2 trillion in health impacts each year, an amount comparable to the combined profits of the world’s 100 largest listed companies.
These synthetic chemicals enter the human body through food, water, and air, and accumulate over time. Even limited accounting of environmental impacts like agricultural losses and costs to meet water safety standards adds another $640 billion annually to the total burden.
How These Chemicals Enter the Food Chain
- Pesticides: Used extensively in industrial agriculture to protect crops, leaving residues on produce and in soil.
- Phthalates & Bisphenols: Plasticizers and stabilizers widely found in packaging, food processing equipment, and disposable containers.
- PFAS: Persistent, bioaccumulative compounds used in grease-resistant food wrappers and non-stick cookware that can contaminate soil and water.

Why These Chemicals Cause Harm: Science of Exposure
Endocrine Disruption and Developmental Impacts
Many of the food system’s synthetic chemicals are known endocrine disruptors, substances that interfere with natural hormone systems. These disruptions are linked to reproductive disorders, obesity, metabolic disease, and cognitive impairments, and can have lifelong effects, especially when exposure occurs in utero or during childhood.
Chemical pesticides like organophosphates, neonicotinoids, and herbicides have also been linked to neurological damage, hormone disruption, and chronic illnesses. Exposure can occur through ingestion of residues on fruits, vegetables, and grains, as well as through contaminated water sources.
Persistence and Bioaccumulation
PFAS, sometimes called “forever chemicals” because they resist breakdown, are of particular concern because they accumulate in the environment and in human tissue. Studies have detected PFAS in drinking water supplies, soil, and even rain, and these compounds are associated with liver damage, immune dysfunction, and increased cancer risk.
Because many of these chemicals are persistent and widely dispersed, they can enter food chains and biological systems globally, creating chronic exposure even at low doses.

Economic Burden: A $2.2tn Annual Hit
The global economic cost associated with the food system’s synthetic chemicals is not just theoretical; it’s measurable and substantial. According to the 2025 assessment:
| Metric | Estimated Value | Notes |
|---|---|---|
| Annual health burden | $2.2 trillion | Costs from disease, disability, loss of productivity |
| Additional ecological impacts | $640 billion | Agricultural losses, water safety costs |
| Chemicals on the market | 350,000+ | Many are untested for safety |
| Increase in chemical production since the 1950s | 200× | Massive surge in synthetic chemical output |
This burden includes direct healthcare costs, lost workdays, reduced productivity, disability, and premature mortality resulting from chemical-linked diseases. Some researchers argue the true burden is likely even higher, as many chronic effects and ecological damages remain unpriced or undercounted.

Health Impacts on People and Populations
Cancer and Chronic Diseases
Long-term exposure to synthetic chemicals in food and packaging has been associated with elevated risks of multiple cancers, including breast, prostate, and colorectal cancers. Research suggests that additives like bisphenol A (BPA) and certain pesticides may contribute to tumor growth through endocrine disruption and genotoxicity.
Emerging studies also link chemical exposures to metabolic diseases, such as obesity and type 2 diabetes, with evidence showing that some plasticizers can interfere with fat metabolism and insulin function.
Reproductive and Developmental Harm
Exposure to endocrine-disrupting chemicals early in life can impact fertility and child development. For example, PFAS exposure has been associated with reduced fertility, thyroid disruption, and lowered birth weights in various populations. Researchers warn that such effects could have demographic consequences over decades.

Regulatory Gaps and Weak Oversight
A major driver of these health costs is the lack of robust regulatory oversight for many synthetic chemicals. Unlike pharmaceuticals, which undergo rigorous safety testing before approval, most industrial chemicals used in food packaging, agricultural processes, and processing equipment face little pre-market safety evaluation and limited post-market monitoring.
Organizations such as the Joint FAO/WHO Expert Committee on Food Additives (JECFA) provide guidance on acceptable contaminant levels, but many countries lack resources or policies to enforce global best practices consistently.

What Needs to Change: Solutions and Policy Options
Strengthen Chemical Safety Assessments
Expanding global capacity for pre-market safety testing, transparent risk assessment, and ongoing monitoring of synthetic chemicals is essential. This includes greater investment in science to understand combined exposures and long-term effects, not just individual chemicals in isolation.
Reduce Use in Food Production and Packaging
Phasing out chemicals of great concern, especially PFAS, certain plasticizers, and persistent pesticides, and replacing them with safer alternatives or sustainable practices could reduce exposure and long-term health costs.
Improve Regulatory Coordination
Coordinating international standards and enforcement — harmonizing approaches across major regions like the EU, U.S., and Asia- would help ensure a level playing field for industry while protecting public health and ecosystems.
Promote Safer Agricultural Practices
Supporting organic and regenerative farming that minimizes reliance on synthetic pesticides, and adopting technologies such as biological pest control, cover cropping, and soil health management can lessen chemical burdens on food and water.

Broader Implications: Environment, Society, and Equity
The health burden of synthetic chemicals is not just a medical issue; it’s a societal and environmental justice challenge. Vulnerable populations, including children and low-income communities, often face higher exposures due to proximity to agricultural zones, limited access to clean water, and reliance on packaged foods.
In addition, chemical runoff and residues harm ecosystems and wildlife, disrupting reproductive cycles in fish and amphibians, damaging soil health, and polluting waterways, impacts that ripple through food chains and livelihoods.
Addressing the food system’s synthetic chemicals is thus part of a larger imperative to protect planetary health, safeguard food security, and reduce inequalities in health outcomes worldwide.
The mounting evidence shows that the food system’s synthetic chemicals are not just environmental pollutants; they represent a global public health crisis with massive economic costs. Tackling this challenge will require bold science-based policy, international cooperation, and a shift toward safer, sustainable food systems for future generations. Lessons from emerging research and policy innovations provide a path forward, but the clock is ticking.
