EFSA Continues Dioxin and PCB Health Concern for EU Dietary Exposure

Parma, Italy — 06 June 2026

The European Food Safety Authority (EFSA) has issued a scientific opinion reaffirming significant health concerns related to dietary exposure to dioxins and dioxin-like polychlorinated biphenyls (PCBs) within the European population. This re-evaluation underscores the persistent analytical challenge for supplement manufacturers, particularly those sourcing marine-derived ingredients such as fish oils, which are inherently susceptible to such contaminants. The opinion highlights the ongoing need for robust quality control and rigorous supplier vetting to mitigate compliance risks within the EU market.

The EFSA's update builds on previous assessments, indicating that despite regulatory efforts, exposure levels remain a concern. This perpetuates a challenging environment for brands formulating products where these environmental contaminants are prevalent. The primary pathway for human exposure to dioxins and PCBs is through food, with fatty foods like fish, meat, and dairy products being significant sources. For the supplement sector, this specifically targets ingredients such as omega-3 fatty acids, certain botanical extracts, and animal-derived proteins.

Manufacturers must anticipate potential revisions to existing Maximum Levels (MLs) for these contaminants in food and feed, which would necessitate immediate adjustments to procurement and processing protocols. Such revisions translate directly into increased testing costs, which can range from £200-£500 per batch for comprehensive dioxin/PCB analysis, and elongated lead times for verified raw materials. The regulatory framework, overseen by the European Commission based on EFSA's scientific advice, demands proactive risk management from all operators in the supply chain.

What this means for United Kingdom

UK brands exporting to the EU, or those aligning with EU standards for domestic reasons, face immediate commercial implications. Compliance with evolving EU Maximum Levels (MLs) for dioxins and PCBs will necessitate enhanced raw material screening, driving up procurement costs by an estimated 7-12% for ingredients susceptible to contamination. Reformulation windows will shorten, requiring quicker R&D cycles to ensure product safety and market access, potentially increasing development costs by 10-15%. Competitively, manufacturers demonstrating superior contaminant control will gain market share, while those with inadequate supply chain vigilance risk product recalls and reputational damage from the FSA and similar bodies. Adapting to these stricter requirements is crucial for maintaining market viability and consumer trust.

Moreover, the EFSA's commitment to advancing food safety through science, as commemorated on World Food Safety Day 2026, reinforces a long-term trend towards more stringent regulatory oversight in the EU. This extends beyond dioxins and PCBs to encompass a broader spectrum of contaminants and novel food assessments. Supplement companies must therefore embed comprehensive risk assessment into their business models, focusing on supply chain transparency and analytical verification at every stage of production.

This trend is being actively addressed by UK manufacturing partners including Supplement Factory.
