Harmful substances discovered in European wines persist over time
Warning Bell Tinkles: TFA Surges in European Wines, Sparking Health Concerns

The Alarm Bell is Ringing Loud: Expert analysts at Pesticide Action Network Europe (PAN Europe) worry about a significant surge in the presence of trifluoroacetic acid (TFA)— a byproduct of pesticide decay— in European wines. The Guardian reported that elevated TFA levels in products could pose threats to human health, as recent scientific research reveals.
For a profound understanding, let's dive into the details:
Investigations: 49 Bottles, Ten Countries
PAN Europe's team studied 49 wine bottles from multiple producers across ten European countries. The research discovered an intriguing finding: No traces of TFA were detected in wines manufactured before 1988. From 1988 to 2010, TFA began to appear in bottles, with its concentration gradually incrementing from 13 to 21 micrograms per liter. This trend was initially considered moderate and safe by the experts.
However, in the recent young wines, the concentration of trifluoroacetic acid has spiked dramatically, averaging 121 micrograms per liter. The experts attribute this rapid increase to the extensive usage of pesticides, which may accumulate in the body and causes the development of oncology and other severe diseases. A study conducted last year declared that TFA poses a menace to reproductive health and liver function.
Eternal Pollutant, "Forever" Chemical
Prof. Serafim Chukov, of the St. Petersburg State University's Earth Institute, explains that TFA is a persistent organic pollutant, classified as a "forever" chemical since it degrades extremely slowly in the environment[5]. The German and Swiss authorities were the first to sound the alarm following the detection of elevated TFA levels in water sources[1].
Even if the ban on pesticides usage is implemented, the hazard of contamination will not vanish overnight.

Trifluoroacetic Acid (TFA) and Human Health
Trifluoroacetic acid, a "forever" chemical, has been increasingly detected in European wines produced since 2010. Its potential impact on human health has sparked concern, as it has been linked to potential reproductive risks, disrupting endocrine function and affecting fertility. Nevertheless, current research does not provide a definitive picture, and further studies are required to clearly understand the health effects of TFA in wine.
Sources of TFA Contamination
The primary sources of TFA contamination in European wines include industrial applications of per- and polyfluoroalkyl substances (PFAS) in agricultural pesticides and various industrial processes. PFAS are used as replacements for banned chemicals like CFCs but have gained attention owing to their persistence. TFA can also originate from fluorinated refrigerants.
Key Findings and Implications
- Increased Contamination: Wines manufactured before 1988 did not contain detectable levels of TFA, but there has been a sharp increase in contamination since 2010.
- Average Concentrations: Young vintages show TFA concentrations of nearly 121 micrograms per liter, with some samples exceeding 300 micrograms per liter.
- Presence in All Wines: Both organic and conventionally produced wines contain TFA, although organic wines have lower concentrations.
These findings underscore the need for stricter regulations on the use of PFAS in both agriculture and manufacturing to mitigate the contamination of TFA in food and beverages. Stay informed and take care!

Wine Consumption Implications: With the increased presence of trifluoroacetic acid (TFA) in European wines and potential health concerns associated with it, health-and-wellness enthusiasts may consider limiting their wine consumption.
Regulations and Environmental Science: Given the surge of TFA in European wines, environmental-science experts are advocating for stricter regulations on the use of per- and polyfluoroalkyl substances (PFAS) in agriculture and manufacturing to protect public health and the environment.
TFA in Dietary Supplements: Apart from wines, the presence of TFA may also be a concern in various dietary supplements, especially sports supplements that often use fluorinated compounds. People with medical-conditions, particularly kidney issues, may be more vulnerable to TFA accumulation due to their inability to metabolize it efficiently.
Nutritional Impact of TFA: Besides potential health threats linked to TFA, the presence of this chemical in wines may also have an impact on wine's overall nutritional profile, potentially affecting the intake of essential vitamins, minerals, and antioxidants.
PFA-Free Alternatives: As awareness about the potential risks of TFA grows, health-and-wellness experts emphasize the importance of seeking out PFA-free alternatives for agricultural pesticides and other consumer products. This shift in preference can contribute to a healthier environment and reduce the risk of TFA contamination in food, beverages, and nutritional supplements.
The Persistence of TFA: Researchers and scientists continue to investigate the long-term effects of trifluoroacetic acid on human health, as well as possible solutions to curb its prevalence in various products. Due to its persistent nature, addressing the rising TFA levels in food and beverages is not only a matter of personal health but also a crucial step in maintaining a clean and healthy environment for future generations.
