Assuring Safety of Ready to Eat Food (RTE) in Relation to Listeria monocytogenes and Regulation 2073/2005
New industry-led good practice guidance for manufacturers and retailers of certain ready to eat (RTE) foods has been published to help Food Business Operators (FBOs), Competent Authorities (CAs) and enforcement officers manage the risk posed by L. monocytogenes in those products.
The guidance (https://bit.ly/4rtqmLI), which was developed by the Chilled food Association (CFA) in consultation with regulators and industry, reiterates that food safety must be assured through HACCP, supported by Good Manufacturing Practice (GMP), Good Hygienic Practice (GHP) and Pre-Requisite Programs (PRPs).
The guidance is timed to help prepare businesses for a change to the EU Regulation, applicable from 1 July 2026 in the EU and other jurisdictions applying EU law including Northern Ireland. It explains how to assure food safety with respect to L. monocytogenes including setting and evidencing shelf life and compliance with the amendment to criterion 1.2b brought in by Regulation 2024/2895. The 1 July change will apply where shelf life evidence for RTE foods supporting the growth of L. monocytogenes is deemed insufficient by CAs.
The document is a significant update of shelf life guidance issued by CFA in conjunction with a range of other food trade associations and FSA in 2010. It will be welcomed by all who have been seeking clarification on the potential impacts of the changes to the Regulation. Clarification is offered on key points including:
- HACCP is mandatory as the foundation for food safety; HACCP plans must be demonstrably supported by robust GHP, GMP and PRPs.
- Listeria monocytogenes is the only Listeria species regulated because of its ability to cause serious human disease and to survive and grow under chilled conditions.
- There are no changes to fundamental legislated food safety assurance requirements including shelf life determination.
- There is no standard method to estimate or set the shelf-life of a food product because there are many different factors that can affect the product safety and quality. Detail is given on approaches to be followed together with limitations and special considerations, data usage, and the application of the legislation in the context of HACCP.
- Shelf life decisions must be evidence-based and take into account physicochemical parameters, the behaviour of all relevant microorganisms, intended consumers (including vulnerable groups), historical HACCP and Food Safety Management System data including food sampling and other shelf life study data where appropriate.
- Environmental monitoring and ingredient controls are essential components of a preventive strategy for Listeria monocytogenes; detections in the environment or ingredients must trigger defined corrective actions.
- Support for enforcement by clarifying expectations for sampling, interpretation of results, and actions when L. monocytogenes is detected at different levels in ingredients or finished products.
The guidance has been specifically developed for: manufacturers and retailers of RTE foods that may support growth of L. monocytogenes, with the exception of foods intended for infants or for special medical purposes; Competent Authorities and enforcement officers seeking a practical reference for inspection and enforcement and supply chain partners and trade associations advising members on compliance with microbiological criteria and evolving regulatory requirements.
Developed in direct response to questions and concerns the guidance is designed to be easy to apply, comprising a range of practical resources and case studies:
- Decision tree to determine applicability of the guidance.
- Tables summarising microbiological criteria and the amended criterion 1.2b.
- Checklists for purchasing RTE ingredients.
- Environmental monitoring programme design and usage.
- Detailed approaches to establishing and justifying shelf life (physicochemical data, scientific and historical data, experimental studies).
- Worked shelf life examples (e.g., cheese and sandwich scenarios).
- Usage and limitations of predictive modelling, durability and challenge testing.
- Example types of historical data to be collated by FBOs in support of food safety assurance and shelf life.
- Q&A addressing common operational questions and enforcement scenarios.
The guidance references the Microbiological Criteria for Foodstuffs Regulation 2073/2005 (as amended) and the amendment introduced by EU Regulation 2024/2895 (criterion 1.2b), which applies in the EU and in jurisdictions applying EU law from 1 July 2026.
In the UK context, references to EU legislation should be read as applying to Northern Ireland as EU law and to England, Wales and Scotland as assimilated law where relevant.
As with previous versions the guidance will be updated in light of practical experience and regulatory developments; feedback from industry and enforcement bodies is welcomed.
Karin Goodburn MBE, Chair, Industry Listeria Group, Chilled Food Association
“This vital guidance brings practical clarity to the steps manufacturers and other FBOs must take to assure the safety of RTE foods with respect to L. monocytogenes including how to establish and evidence shelf life. It places prevention at the centre of operations with strong HACCP, backed by good hygiene and robust prerequisite programs and gives clear direction on how to set shelf life, how to respond to detections of L. monocytogenes and how to use environmental monitoring program data to support food safety.
“We believe the guidance gives FBOs the necessary tools to enable them to review and, where necessary, update HACCP plans and PRPs to reflect the guidance as well as ensure shelf life justifications are documented and supported by appropriate data. It will also allow them to strengthen environmental monitoring and supplier controls and seek technical expertise if internal capability is insufficient.
“We are grateful for the input and support of member organisations of the Industry Listeria Group, the Food Standards Agency and Food Standards Scotland.”
James Cooper, Deputy Director of Food Policy, Food Standards Agency and Garry Mournian, Head of Policy and Regulatory Affairs, Food Standards Scotland
“We welcome this updated industry-led guidance, which provides practical advice to help food businesses manage the risk of Listeria monocytogenes in ready-to-eat foods. Assuring food safety through robust HACCP systems, good hygiene practices, and evidence-based shelf-life determination is essential to protect consumers, particularly vulnerable groups. This guidance will support manufacturers, retailers, and enforcement officers in meeting regulatory requirements and maintaining high standards of food safety.”
Bronwen Percival, Technical Committee Chair, Specialist Cheesemakers Association:
“We welcomed the chance to work with the FSA to bring clarity to the process of setting shelf life. For cheesemakers producing soft cheeses where Listeria can grow, the rules can feel daunting. Clear guidance on best practice is a win for everyone. For cheesemakers, establishing shelf life on certain products can be complex. Working with the FSA to clarify expectations supports producers and protects consumers: exactly what we’re here for.”
Devina Sankhla, Food Policy Advisor at the British Retail Consortium (BRC):
The BRC is pleased to support and endorse this revised guidance. It is a valuable resource for food businesses and enforcement, providing clear and practical advice to support compliance with food hygiene and food standards in relation to the management of Listeria monocytogenes in chilled food production of ready to eat products.

It’s always exciting to be the subject of positive media interest. Which is what happened when the IFST approached the CEd team for a profile on the initiative and progress since 2011.









CFA is keeping its members abreast of the latest developments in activity following up on the 19 May 2025 UK-EU High Level Summit’s announcement on forthcoming negotiation of an SPS Agreement between the UK and EU.
CFA’s work to support established best practice in setting shelf life with respect to Listeria monocytogenes continues with the publication by the ECFF of their endorsed version of Shelf life for Ready to Eat Food in Relation to L. monocytogenes. The document was originally developed by CFA in 2010 with a coalition of organisations, including numerous food trade associations and the BRC, the Chartered Institute of Environmental Health, the Health Protection Agency (now UKHSA), and the Food Standards Agency.
A new CFA initiative recently saw a group of its member companies discussing the benchmarking of road traffic accident data for their fleet operations and sharing learning about improving the safety of HGV and van movements. As a first step, accident data will be submitted to CFA for collation and sharing, which in the future may be compared to that from the wider logistics sector.

Karen Birch has joined CFA as Technical Services Manager. She is the main point of contact for Members with database software questions, managing access to CFA’s microbiological databases, setting up SUSSLE training and much more.
Over the years CEd has enjoyed working with award-winning science teacher and best-selling textbook author Sam Holyman (left). The partnership continues with Sam creating four new STEM activities that use food to explore scientific principles including using milk to investigate surface tension and macronutrients.

It’s always good to get out to face to face events to chat with teachers and learners in real life. That’s exactly what CEd’s Charlotte Patrick has been doing over recent months.
CEd’s library of resources continues to grow with more than 100 lesson plan ideas, experiments and practical resources now available from the Shopify website. As CEd’s Charlotte explains: “The suggestions are ideal for schools to use on one of the many themed days and weeks occurring throughout the year. To help in teachers’ planning we’ve researched science and food themes to inspire and put them into a free to download calendar also available on 
Chilled Education’s young scientists Tilly and Morgan helped develop many of the Store Cupboard Science resources and were delighted and proud to receive the trophy.
It’s now more than eight years since the UK’s referendum vote and the huge complexity, costs, inefficiencies and negative impacts on GB food supply and trade of new Brexit bureaucracy agreed by UK government (UKG) with its largest trading partner – the EU – are becoming ever clearer.
More than 80 organisations submitted comments to the consultation on the EU’s proposed changed to Listeria monocytogenes regulations (microbiological criteria of foodstuffs Reg 2073/2005). These included the CFA-led Industry Listeria Group which submitted an extensive response which can be found on the CFA website https://bit.ly/4dqDPvU.








went to those in need through partners such as Company Shop and FareShare. Since 2017 approximately 50 million meals have been redistributed by our members.













The STEM Learning Ambassadors network asked CEd to work with them on a series of virtual talks for schools and colleges. CEd’s Charlotte developed a presentation to: ‘Inspire young people about food science and raise awareness of careers in chilled food industry’ She offered a 30min exploration of career the chilled food sector covering subjects ranging from the roles needed to make a chicken salad to the various routes into the industry.
