The Clean Label Project in the United States has released an extensive report that has stirred debate across the coffee world, revealing findings that undermine the long-standing perception of organic coffee as a guarantee of purity. The report shows that every single organic coffee sample tested contained industrial and environmental contaminants, including residues of pesticides that are officially banned in organic agriculture, raising fundamental questions about certification credibility and agricultural oversight.

The investigation covered fifty-seven different coffee products representing forty-five leading brands in both the U.S. and global markets. Each product was subjected to a rigorous series of laboratory analyses, with more than seven thousand individual tests performed in total. Samples included coffees across all common roast levels—light, medium, and dark—and were taken from the most prevalent packaging formats on the market, from bags and pods to metal cans.

The most striking and controversial result was the detection of aminomethylphosphonic acid, or AMPA, in one hundred percent of the organic samples. AMPA is a breakdown product of glyphosate, a herbicide that has generated global controversy due to its suspected health risks and that is strictly prohibited in certified organic farming. According to the report, the universal presence of AMPA in every sample tested delivers a shock to consumers, many of whom turn specifically to organic coffee in search of a product free from chemical residues.

Although glyphosate itself was detected in only a few of the samples, the consistent appearance of its by-product across all organic coffees raises alarming concerns about the pathways through which contamination occurs. Researchers point to multiple possibilities: runoff from neighboring conventional farms contaminating organic fields, wind drift carrying spray particles across boundaries, or legacy residues lingering in soils for decades that continue to affect crops long after application has ceased.

The report did not stop at AMPA. It also revealed the presence of heavy metals in every single sample, including lead, cadmium, mercury, and arsenic. While most levels remained below the maximum thresholds set by the European Union for food safety when measured against typical daily consumption volumes, experts stress that cumulative exposure over long periods cannot be dismissed as harmless. For regular coffee drinkers, this raises concerns that extend well beyond a single cup.

Equally concerning was the universal detection of acrylamide, a chemical that naturally forms during the roasting process and is classified as a potential carcinogen. Levels of acrylamide were particularly high in medium roasts compared to very light or dark roasts, suggesting that the most popular roast category among consumers could also pose the greatest risk.

The study further highlighted the role of packaging in contamination. Phthalates, chemical compounds associated with plastics and known for their potential to leach into food and beverages, were especially prevalent in canned coffees, followed by pods, with bagged coffee showing the lowest levels. Researchers emphasized that packaging is not simply a marketing tool or a method to preserve flavor; it plays a direct role in determining the chemical purity of the product consumed.

Geographic origin was another factor influencing contamination. African coffees tested in the study generally displayed lower levels of heavy metals, while Hawaiian coffees showed higher concentrations, a result attributed to the mineral-rich volcanic soils in which they are cultivated. This underscores that agricultural environments themselves can significantly shape the safety profile of the beans, regardless of organic practices.

The Clean Label Project stressed that the purpose of this study is not to frighten consumers or to dissuade them from drinking coffee, but rather to raise awareness of hidden risks and equip people with the knowledge they need to make informed decisions. Among its recommendations: consumers should look for brands with independent certifications that verify product testing, favor darker or very light roasts to reduce acrylamide exposure, avoid canned coffee in favor of bagged products, and follow ongoing testing results published regularly by the organization.

The broader implications of the report are profound. Coffee is one of the most consumed beverages in the world, with more than one billion people drinking it daily and a U.S. market valued at more than 269 billion dollars in 2024 alone. The findings remind us that the coffee industry, despite its global cultural and economic importance, is not immune to environmental and industrial contamination. For producers, regulators, and consumers alike, the lesson is clear: the label “organic” does not automatically guarantee absolute purity.

The report concludes with a call for stricter oversight of organic certification processes, greater transparency across supply chains, and more independent research to restore and sustain consumer confidence. In a world where billions of cups of coffee are consumed every single day, the integrity of this industry matters not only for enjoyment and tradition but also for the health and trust of communities worldwide.
