In June 2026, the European Union established the first binding maximum levels for Mineral Oil Aromatic Hydrocarbons (MOAH) in food, including spices, dried herbs, and tea. This landmark decision marks a transition from voluntary guidance to a rigorous legal framework, aimed at mitigating potential genotoxic and carcinogenic risks associated with mineral oil migration. For importers and food brands, ensuring compliance with these new MOAH limits is essential to maintaining market access as enforcement takes hold in 2027. This regulatory shift represents a seismic change in the European food safety landscape, requiring stakeholders to rethink how they evaluate the safety of their global supply chains.

Understanding the EU MOAH Limits in Spices

Mineral Oil Aromatic Hydrocarbons are complex mixtures of hydrocarbons often found as environmental contaminants. Unlike pesticides, which are typically managed through farm-level interventions, MOAH contamination frequently originates from industrial sources such as machine lubricants, processing equipment, or migration from packaging materials like jute bags during transport. According to Eurofins, the adoption of these limits signifies a proactive regulatory approach to food safety. The EU’s move is grounded in the European Food Safety Authority (EFSA) opinions, which highlight that MOAH compounds, particularly those with 3-7 aromatic rings, may act as genotoxic carcinogens. Because these substances can accumulate in the human body, the EU has moved beyond the previous "zero tolerance" or "as low as reasonably achievable" (ALARA) principles toward strict, enforceable maximum residue levels (MRLs) defined by the concentration of specific hydrocarbon chains.

The regulatory framework, as outlined in Commission Implementing Regulation (EU) 2026/1206, necessitates a comprehensive audit of the entire supply chain. Buyers can no longer rely solely on legacy pesticide-free certifications or simple visual inspections. Instead, quality assurance protocols must now account for industrial contact points, from the site of harvest to final warehouse storage. This includes evaluating the hydraulic oils used in threshing machinery, the lubricants applied to grinding equipment in processing plants, and the chemical composition of transport packaging. Jute bags, often treated with mineral-oil-based batching agents to soften fibers, are a primary concern for the spice and herb industry. This shift demands a level of transparency that defines our sourcing practices, moving beyond basic origin verification to granular process mapping.

The challenge for importers is that MOAH contamination is often sporadic. A batch of peppercorns may be pristine at the point of origin, only to be contaminated during transit in a shipping container where lubricants leak from cooling units or where the interior lining of the container itself introduces hydrocarbon residues. Consequently, the regulation forces brands to adopt a "safety-by-design" approach that encompasses the entire lifecycle of the raw ingredient.

The Treedha Perspective on Purity

At Treedha, we have long maintained that true purity is a consequence of intentional supply chain design. The introduction of these standards reinforces our commitment to steam-sterilised ingredients. By controlling the processing environment, we eliminate variables that contribute to contamination. Steam sterilisation not only reduces the microbial load of spices and herbs but also serves as a critical control point (CCP) where we can monitor for moisture and heat-related degradation, ensuring that no industrial lubricants or extraneous chemical agents are introduced during the sanitisation phase.

Our rigorous lab-testing protocols, which align with both EU and US safety limits, ensure that every spice and pantry staple meets the highest international standards of provenance and safety. To combat MOAH risks, we have enhanced our analytical testing to include Gas Chromatography-Flame Ionisation Detection (GC-FID) and, where necessary, Comprehensive Two-Dimensional Gas Chromatography (GCxGC-FID) to separate complex hydrocarbon mixtures. This precision allows us to verify whether a sample exceeds the newly mandated EU thresholds.

Proactive testing is no longer merely a best practice; it is a fundamental requirement for risk management. Brands that integrate these testing protocols into their procurement strategy will be better positioned to avoid border rejections and costly recalls as the industry adapts to these 2027 compliance mandates. We view the 2026 regulations as a validation of our long-standing philosophy: that the quality of a product is non-negotiable and that transparency must extend from the farm gate to the retail shelf.

Comparison of Contaminant Compliance

Navigating the transition requires understanding how the new MOAH limits compare to other well-established food safety regulations. The table below outlines the primary contaminants, their typical origins, and the specific mitigation strategies required for 2027 compliance.

This comparison highlights that while some risks—such as pesticides—are managed through agricultural management (GAP), MOAH is fundamentally a post-harvest, industrial, and logistical risk. It requires the food industry to collaborate closely with packaging manufacturers to ensure that materials like liners, adhesives, and inks are strictly food-grade and free from mineral oil migration pathways.

Navigating the Future of Food Safety

For businesses looking to navigate these changes, maintaining full transparency regarding the source and handling of ingredients is paramount. The EU's 2027 enforcement deadline leaves little room for ambiguity. Suppliers must now provide documentation confirming that machines involved in harvesting, grinding, and blending are maintained with food-grade, non-toxic lubricants. Furthermore, transport logistics must be audited for the use of "clean" transport methods, avoiding recycled paper bags or jute sacks that have not been certified as free from hazardous mineral oils.

By aligning with partners who perform detailed analytical testing, you ensure that your product range remains compliant and competitive in a stringent regulatory landscape. At Treedha, we have invested in the infrastructure to identify these contaminants at their source, ensuring that our partners in the retail and food manufacturing sectors are buffered against the unpredictability of shifting international standards.

The complexity of the global spice supply chain makes the implementation of these regulations a significant hurdle for many. However, through rigorous vetting, advanced laboratory testing, and the elimination of problematic packaging materials, we can collectively raise the bar for food safety. We invite you to contact us to discuss how our stringent quality standards can support your supply chain requirements and ensure that your ingredients remain ahead of the curve as the 2027 enforcement period begins. Embracing these standards is not merely about ticking a regulatory box; it is about building a foundation of trust that protects consumers and secures the integrity of your brand in an increasingly cautious global market.

Frequently asked questions

What are MOAH limits in food?

MOAH (Mineral Oil Aromatic Hydrocarbons) are industrial contaminants. As of June 2026, the EU has introduced binding maximum levels for these substances in categories such as spices, tea, and dried herbs to prevent carcinogenic risks.

Why is MOAH a concern for spice importers?

MOAH contamination often occurs during processing, storage, or transport, such as through machine lubricants or migration from non-food-grade packaging, requiring importers to audit their entire supply chain rather than just the farm level.

When will the new EU MOAH regulations be enforced?

While the regulation was approved in mid-2026, formal adoption and enforcement protocols are expected to be fully active for the 2027 season.

How can brands ensure their spices meet new EU standards?

Brands must implement robust supply chain auditing, move away from reliance on non-verified sources, and perform rigorous lab testing to ensure products adhere to the updated EU Contaminants Regulation.
