Trifluoroacetic acid (TFA) has emerged as one of the most concerning PFAS in Europe’s food supply – particularly in cereals, a staple consumed daily by millions. A report from PAN Europe reveals a widespread and largely unmonitored contamination trend that raises serious questions about food safety, regulatory blind spots, and future monitoring strategies.
Amid this growing concern, liquid chromatography-mass spectrometry has never been more essential, and this is exactly where SCIEX and Phenomenex play a pivotal role.
TFA: A little‑known but ubiquitous “forever chemical”
A first-of-its-kind EU‑wide investigation by PAN Europe shows just how prevalent TFA contamination has become across cereal-based foods. According to the report:
- TFA was found in 82% of sampled cereal products, spanning 16 European countries.
- Wheat-based items, including bread, pasta, and breakfast cereals, had the highest concentrations, consistent with prior findings.
- At these levels, children’s daily cereal consumption may exceed proposed acceptable intakes, with estimated exposures reaching 184% of PAN Europe’s ADI.
TFA forms as a persistent degradation product from fluorine-containing gases (F-gases), pesticides and pharmaceuticals. Once released, it resists breakdown, accumulates in water, soil, crops, and, most critically, ends up in everyday foods.
The findings make one thing clear: food has become a major and underrecognized exposure pathway for ultrashort-chain PFAS such as TFA.
Why detecting TFA is so challenging
Unlike longer-chain PFAS compounds, ultrashort-chain species like TFA are:
- Highly mobile, easily moving through soil, and water
- Difficult to extract with conventional sample prep
- Hard to chromatographically retain and separate due to their small size and polarity
- Often missed in routine PFAS monitoring, which traditionally focuses on PFOS, PFOA, PFNA, and similar compounds
This complexity is a major reason why TFA contamination has remained “unseen and unregulated” across Europe — until now.
To address this analytical gap, labs must rely on high-sensitivity, high-specificity mass spectrometry workflows capable of quantifying ultrashort-chain PFAS at low μg/kg or sub‑μg/kg levels.
SCIEX: Enabling accurate, defensible TFA testing in food
It has become increasingly important for labs to detect even the most elusive contaminants, including ultrashort-chain PFAS such as TFA.
Here’s how SCIEX and Phenomenex technology addresses the analytical challenges:
- Sensitivity suitable for ultrashort-chain PFAS
Modern triple-quadrupole mass spectrometers, including the SCIEX 7500+ system, widely used in PFAS research, provide the sensitivity and resilience required to detect ultrashort-chain PFAS, such as TFA, at trace concentrations.
- End‑to‑end solutions with Phenomenex
For challenging PFAS assays, lab mangers need solutions that can deliver results time and time again. SCIEX and Phenomenex partner to combine expertise in PFAS testing and provide end-to-end solutions for robust and precise quantitation of PFAS compounds in a variety of matrices, enabling labs to:
- Minimize background contamination
- Improve reproducibility
- Meet tightening regulatory expectations

- SCIEX OS software for confident reporting
Advanced analytical software platforms used in PFAS workflows help laboratories process and review large data sets and, separate true findings from matrix interferences, which are all critical when dealing with contaminants such as TFA. These platforms also support traceability and reporting, which become increasingly important as regulatory discussions evolve. SCIEX OS software provides a streamlined platform for acquisition, processing, QA/QC, and reporting across PFAS methods.
Why this matters now for food testing labs
Regulators are beginning to recognize the severity of ultrashort-chain PFAS contamination, but food-based monitoring is still limited. TFA currently escapes most EU food safety monitoring systems, leaving a major surveillance gap.
With rising consumer concern, growing media attention, and clear scientific evidence of widespread contamination, the demand for high‑quality, high‑sensitivity analytical data will only accelerate.
