The Hidden Risks in Convenience: Ultra-Processed Foods Dominate Acrylamide Alerts, Study Finds
A groundbreaking 17-year analysis conducted by researchers at the University of Novi Sad has shed new light on the persistent issue of acrylamide contamination in the European food supply. The study, published in the journal Toxics, reveals that ultra-processed foods (UPFs) are the primary drivers of "serious-risk" and "alert" notifications within the EU Rapid Alert System for Food and Feed (RASFF). As regulatory bodies across the globe grapple with the health implications of process-induced contaminants, these findings underscore a critical intersection between industrial food manufacturing and chemical safety.
Main Facts: The Acrylamide Connection
Acrylamide is a chemical compound that forms naturally in starchy food products during high-temperature cooking processes, such as frying, baking, roasting, or toasting. Specifically, when foods rich in starch, certain sugars, and amino acids—notably asparagine—are heated above 120°C, the Maillard reaction occurs, giving food its characteristic browned color and flavor. However, this same reaction creates acrylamide, a substance classified as a potential human carcinogen.
The University of Novi Sad study analyzed 98 RASFF notifications spanning from 2009 to 2025. By applying the NOVA food classification system, researchers categorized these notifications to determine if there was a correlation between the degree of food processing and the prevalence of contamination. The results were stark: UPFs, defined as industrially formulated products containing ingredients of little to no culinary use, accounted for a staggering 84.7 percent of all acrylamide-related notifications. Furthermore, these products represented 85.7 percent of all notifications classified as "serious risk," highlighting a significant public health concern.
The health risks associated with chronic exposure to acrylamide are well-documented in toxicological literature. The compound is considered potentially neurotoxic, genotoxic, and carcinogenic, with research suggesting links to reproductive and developmental health issues. Moreover, specific studies have identified associations between high dietary intake of acrylamide and an increased risk of breast cancer, among other malignancies.
Chronology: The Regulatory Landscape and Monitoring Trends
The landscape of acrylamide monitoring in Europe has shifted dramatically over the past two decades. A critical turning point occurred in 2017 with the implementation of Regulation (EU) 2017/2158, which established benchmark levels and mandatory mitigation strategies for food business operators.
The data analysis shows a distinct surge in RASFF notifications following the 2017 regulation, and another notable increase in 2019, when the EU expanded the categories of food subject to mandatory monitoring. While a casual observer might interpret this rise as a sudden increase in contaminated food, the researchers clarify that this is a result of improved surveillance and stricter enforcement rather than a deterioration in food safety standards. The regulatory net became finer, allowing authorities to detect and report levels of contamination that might have previously gone unnoticed.
Between 2023 and 2025, the number of notifications remained consistently high, reflecting a sustained focus on compliance. This period has been characterized by increased laboratory testing and a greater emphasis on supply chain accountability, ensuring that the benchmarks set by the EU are not merely suggestions but performance targets that manufacturers are expected to meet.
Supporting Data: Where the Risk Resides
The study highlights that not all food categories carry equal risk. Cereals and bakery products—specifically biscuits, crackers, and crispbreads—topped the list of implicated categories. These items are frequently subjected to intensive thermal processing, which is highly conducive to the formation of acrylamide. Prepared dishes and snack foods, particularly potato chips and fried potato products, followed closely behind.
Of the 98 notifications examined in the study, 28 were categorized as posing a "serious risk" to consumer health. When drilling down into the UPF data, the researchers found that 32.4 percent of these products were categorized as serious-risk, while an additional 14.9 percent were labeled as potentially serious-risk.
This data aligns with broader nutritional surveillance. The 2026 French Total Diet Study (TDS) corroborates these findings, identifying fried potatoes, sauteed potatoes, potato chips, and cookies as the primary contributors to acrylamide exposure among the French population.
Furthermore, the Novi Sad team examined market surveillance studies to account for the variability in acrylamide concentrations. They found that even within a single category, such as breakfast cereals or roasted coffee, there is significant inconsistency. This variability is often linked to the specific technology used in processing. For instance, a 2026 study from the University of Münster highlighted that "gun-puffing"—a common method for creating airy breakfast cereals—tends to result in significantly higher concentrations of acrylamide compared to other thermal processing techniques. This suggests that the industrial process itself, rather than just the raw ingredients, is the primary variable that needs to be optimized.
Official Responses and Regulatory Implications
The findings have ignited calls for a more robust regulatory framework. The researchers at the University of Novi Sad argue that UPFs should be the primary focus of future mitigation and surveillance efforts. They emphasize the need for "optimized processing technologies," where manufacturers utilize vacuum frying, lower-temperature baking, or enzymatic treatments (such as the use of asparaginase) to inhibit the formation of acrylamide at the source.
The European Commission is currently evaluating the potential for moving beyond benchmark levels to establish legally binding maximum levels for specific food categories. This move is supported by consumer advocacy groups who have long argued that voluntary guidelines are insufficient to protect the most vulnerable populations from long-term carcinogenic exposure.
In the United Kingdom, the Food Standards Agency (FSA) is similarly engaged in a comprehensive review of evidence regarding acrylamide occurrence. The FSA is currently gathering data to determine whether current policy is sufficient or if more stringent legislative action is required to ensure that food manufacturers prioritize safety over the industrial efficiency that currently characterizes the production of ultra-processed goods.
However, there is cause for optimism. Industry-wide efforts to mitigate acrylamide have proven successful in specific instances. The most recent French TDS observed a notable decline in acrylamide levels in some of the most commonly consumed foods, including a significant reduction—and in some cases, the total absence—of acrylamide in roasted coffee. This demonstrates that when industry stakeholders are provided with clear, evidence-based mitigation strategies, they are capable of significantly reducing the toxicological footprint of their products.
Implications for Public Health and the Food Industry
The implications of this 17-year analysis are twofold. For consumers, the study serves as a reminder of the importance of dietary patterns. While it is impossible to eliminate acrylamide entirely from a diet that includes thermally processed foods, the dominance of UPFs in the data suggests that reducing the intake of highly processed snacks and bakery products can naturally lead to lower exposure to this contaminant.
For the food industry, the message is clear: the era of lax oversight is ending. As analytical techniques improve and regulatory agencies adopt more rigorous monitoring, the variability in acrylamide levels—which currently fluctuates wildly between different brands and processing methods—will likely become a point of legal and reputational liability.
The researchers conclude that the path forward requires a three-pronged approach:
- Continuous Monitoring: Enhanced, real-time testing of products that undergo high-heat processing.
- Technological Innovation: A systemic shift in how UPFs are manufactured, favoring processes that naturally suppress the formation of process-induced contaminants.
- Regulatory Evolution: The transition from benchmark-based compliance to strict, enforceable maximum levels, particularly for food categories that consistently appear in RASFF notifications.
As the scientific community continues to map the relationship between ultra-processing and chemical toxicity, this study provides a crucial roadmap for policymakers. By targeting the most problematic segments of the food supply—those categorized as UPFs—regulators can address the most significant sources of acrylamide exposure, thereby enhancing food safety standards across the European continent and beyond.
The task ahead is not merely to regulate, but to encourage a fundamental shift in food processing culture. The success of some sectors in reducing acrylamide levels proves that it is possible to maintain the quality and shelf-life of food products while simultaneously prioritizing the health and safety of the consumer. In an age where convenience often dictates market trends, the challenge remains to ensure that these modern comforts do not come at an unacceptable cost to public health.
