June 2026: New Agriculture Standards Enhance Biosecurity and Sustainability

In June 2026, the agriculture sector welcomed five pivotal international standards, addressing critical themes such as biological contamination detection, environmental sustainability, and product safety. These standards, developed by CEN and ISO, deliver robust frameworks for testing soil improvers and growing media, managing aquaculture effluent, and monitoring emissions from tobacco products. Industry professionals, quality managers, and researchers must understand these advancements to maintain compliance and drive responsible innovation. Here, we break down each newly released standard, outlining their practical implications for the agriculture industry.

Overview / Introduction

The agriculture industry is the backbone of food security, ecosystem management, and sustainable production worldwide. International standards ensure agricultural practices are safe, environmentally sound, and market-ready. From fertilizer blends to aquaculture systems and tobacco product evaluation, adherence to updated standards minimizes risks, protects human and animal health, and streamlines trade.

This article unpacks the key developments in five agriculture-related standards published in June 2026. You’ll learn:

• Essential updates to testing methods for biological hazards in soil improvers and growing media
• Detailed protocols for aquaculture effluent management
• The latest requirements for carbon monoxide testing in tobacco heating systems
• Compliance impacts and benefits for organizations

Detailed Standards Coverage

prEN 18278 - Detection of Salmonella spp. in Soil Improvers and Growing Media

Soil improvers and growing media – Detection of Salmonella spp.

This European draft standard ( prEN 18278 ) provides precise methods for detecting Salmonella species in both solid and liquid soil improvers and growing media. Given that biological contamination can pose significant risks to handlers, crops, and consumers, this standard is designed to bolster safety and hygiene controls throughout supply chains. The method specified covers single components (like peat, wood fibers, compost) or blends of fertilizing products, with a clear protocol if soil improvers or growing media are the predominant blend ingredients.

Key requirements include:

• Four-step detection process: pre-enrichment, selective enrichment, incubation on selective media, and colony confirmation using biochemical or serological tests
• Applicability to both solid and liquid forms, and blends, with guidance on which standard to use based on blend composition percentages
• Most Salmonella serovars are detectable with this method; certain strains (e.g., Salmonella Typhi) require extra cultivation steps
• Laboratory safety: emphasis on testing in properly equipped labs under skilled microbial supervision to prevent exposure and cross-contamination

For organizations, implementing this standard tightens hygiene protocols, particularly vital for manufacturers and processors of organic soil amendments, compost, and potting mixes. This in turn reassures stakeholders and regulatory bodies regarding product safety in horticulture and agriculture at-large.

Key highlights:

• Comprehensive procedure based on EN ISO 6579-1, widely recognized for pathogen detection
• Applicability to diverse product matrices, including complex blends
• Enhanced risk management for public health and regulatory compliance

prEN 18279 - Enumeration of Enterococci in Soil Improvers and Growing Media

Soil improvers and growing media – Enumeration of enterococci

prEN 18279 advances hygiene monitoring by providing accurate enumeration of enterococci, important faecal contamination indicators, in soil improvers and growing media. Enterococci counts can be key validators of processing sanitation, both in production and post-processing phases.

The standard applies to solid and liquid products, and similarly guides which protocol to follow in fertilizer blends. The document features detailed sampling, dilution, and plating instructions, culminating in enumeration on selective media, followed by confirmation steps on BEA (Bile Esculin Azide) agar, further supported by optional catalase testing.

Entities involved in producing, handling, or certifying composts and growing mediums can leverage this standard for:

• Regular verification of sanitation and pathogen reduction processes
• Ensuring compliance with EU regulations, particularly for products entering regulated or high-reliability markets
• Maintaining robust batch records for traceability in case of contamination events

Key highlights:

• Supports compliance with EU Regulation (EU) 2019/1009 for fertilizer products
• Direct alignment with established methodologies (EN ISO 7899-2 and ISO/CD 21722)
• Backed by interlaboratory validation for reliability

prEN 18280 - Enumeration of Escherichia coli in Soil Improvers and Growing Media

Soil improvers and growing media – Enumeration of Escherichia coli

prEN 18280 delivers robust protocols for quantifying Escherichia coli (E. coli) in soil improvers and growing media. E. coli remains a premier marker for assessing sanitary quality and hygiene effectiveness in organic fertilizers and blends.

Key features include:

• Mandated use of selective TBX (tryptone-bile-X-glucuronide) agar with pour plating, targeting β-D-glucuronidase-positive strains
• Provides guidance on handling potential false negatives (e.g., E. coli O157 and other β-D-glucuronidase-negative strains)
• Applicability to both solid and liquid product forms, as well as blends, with explicit instructions depending on blend composition
• Strong validation record across multiple participating laboratories, affirming accuracy and reproducibility

Implementation enables industry professionals to systematically monitor, report, and respond to contamination events, aligning with both regulatory directives and market-driven quality demands.

Key highlights:

• Built on EN ISO 16649-2 for standardization
• Comprehensive scope across product types and forms
• Guidance for confirming ambiguous or borderline results

ISO 5622:2026 - Determination of Carbon Monoxide in Electrically Heated Tobacco Products

Tobacco and tobacco products — Electrically heated tobacco products (eHTPs) — Determination of carbon monoxide in the vapour phase of tobacco heating system aerosol by NDIR method with a puffing regime according to ISO 5501-1

Carbon monoxide (CO) emissions from tobacco heating systems are a major focus for both public safety and regulatory bodies. ISO 5622:2026 specifies a reliable test method using a non-dispersive infrared (NDIR) analyzer to measure CO concentrations under controlled ‘puffing’ conditions. The technique aligns with ISO 5501-1, ensuring consistent and comparable data collection across the globe.

The standard covers:

• Stepwise guidance for sample conditioning, system calibration, and vapor phase collection
• Strict apparatus and reagent requirements
• Repeatability metrics ensuring confidence in emission reports
• Clear mandates for laboratories on test reporting, calculation of results, and addressing emissions outside of calibration limits

For manufacturers and quality laboratories, this standard:

• Facilitates transparent product performance assessment
• Eases demonstration of regulatory compliance, especially where products claim reduced emissions
• Supports innovation by providing clear, reproducible test metrics

Key highlights:

• Based on well-validated international methodology
• Supports compliance and safety assessment for a rapidly evolving product category
