Plant-Based Alternatives: A Study Reveals the Presence of Mycotoxins and Calls for Regulation

The Rise of Plant-Based Alternatives in the Face of a Microscopic Reality

The growing adoption of plant-based diets is permanently transforming our supermarket aisles. While these new consumption patterns address environmental and ethical concerns, a recent analysis highlights a microscopic component in these specific products that has been little studied until now. In a report written by journalist Harry Cockburn and published on May 6, 2026, attention is drawn to an unexpected prevalence of specific natural compounds within these alternatives.

A team of researchers examined plant-based foods and beverages sold in the United Kingdom. Their work, the results of which were published in the scientific journal Food Control, reveals the widespread presence of mycotoxins in hundreds of products available in supermarkets.

The scale of the discovery is based on a representative sample of 212 rigorously tested products. The results of the analyses are unequivocal: every single sample examined contained at least one of the 19 different types of mycotoxins identified by the scientists during this screening campaign.

The Source of Toxins in Everyday Products

To understand these results, it is important to define the nature of these undesirable substances. Mycotoxins are toxic compounds naturally produced by fungi. In small quantities, these substances pose little risk to the human body. However, they routinely find their way into plant-based foods due to the very nature of their composition.

Indeed, the raw materials essential for producing these substitutes—such as grains, legumes, and seeds—can be exposed to mold. This fungal contamination typically occurs during critical stages of field cultivation or during storage in agricultural silos.

The diversity of the 212 products tested illustrates the extent of this exposure. The researchers analyzed a wide range of meat and dairy alternatives designed to replace traditional burgers, as well as vegetarian chicken pieces and vegan sausages. As for beverages, oat, almond, and soy milks were also scrutinized, confirming the presence of these fungal compounds in everyday diets.

Levels Within Standards, but a Risk of Accumulation

The research team, composed of academics from the University of Parma in Italy and Cranfield University in Bedford, UK, was keen to qualify these findings. Although a variety of mycotoxins were detected across all plant-based alternatives, the levels measured in the British foods tested remained below the guideline thresholds recommended by the European Union.

According to the study’s authors, these moderate concentrations reflect the rigor of current manufacturing processes, highlighting what they describe as the high-quality standards of the British food industry.

Nevertheless, the scientists issued a warning regarding long-term consumption habits. They caution that a diet consisting largely of meat and dairy substitutes could lead to a gradual accumulation of mycotoxins in the body, which could potentially cause health problems if the situation is not properly managed.

Researchers in the journal Food Control detail the extent of these health risks: “In very severe cases, exposure to mycotoxins can cause health problems such as liver and kidney damage, a weakened immune system, and cancer.”

A regulatory vacuum amid rapid market growth

The study highlights a modern paradox: consumption of plant-based alternatives to dairy and meat has risen sharply, but scientific research to determine exactly what people are eating—and the potential health implications—has not kept pace.

The research team is closely monitoring this gap. They note: “The European market for plant-based products has experienced unprecedented growth in recent years.” They go on to add that “although the environmental and nutritional benefits of increased consumption of plant-based products are well established, gaps still exist in their safety assessment, particularly regarding the presence of potential unregulated contaminants.”

This lack of comprehensive data currently prevents researchers from accurately mapping the potential risk. The authors explain: “With only a few studies exploring the prevalence of mycotoxins in [plant-based meat alternatives] and [plant-based beverages], a clearer picture of the occurrence of mycotoxins in plant-based foods is still lacking,”

Risk Assessment and Call for Prevention

Andrea Patriarca, a lecturer in mycology at Cranfield University, offers a reassuring yet cautious perspective on these findings. She highlights the ubiquitous nature of these compounds: “Mycotoxins are naturally present in food and cannot be completely avoided. As consumers, we should not be frightened or deterred from enjoying a variety of products.”

The real challenge lies in institutional oversight and the creation of legal frameworks adapted to these new habits. She explains: “However, a significant concern arises when new foods enter the market, as there are currently no established regulations to monitor mycotoxins. Our research data helps food safety organizations assess risks, particularly in complex, multi-ingredient products.”

To address these gaps, scientific teams are continuing their investigations on a European scale. Andrea Patriarca concludes by outlining the next steps in their work: “We are currently collaborating with the University of Parma to assess the risks the population faces based on different dietary habits. Our goal is to advise policymakers and raise awareness among vulnerable consumers.”
