EU Regulation 2024/2895: What Changes for Listeria Control in RTE Foods Starting July 1, 2026
Published: June 11, 2026
Table of Contents
Regulation (EU) 2024/2895 entered into force on December 11, 2024 and will become effective for operators starting July 1, 2026. For companies producing ready-to-eat (RTE) foods, this is not a minor administrative update: it is a paradigm shift in how the control of Listeria monocytogenes is defined, documented, and demonstrated throughout the production chain.
Why this regulation, and why now?
Listeria monocytogenes is not a new topic for food safety professionals. But epidemiological data from European surveillance authorities now provide a precise measure of the scale of the challenge.
According to the ECDC’s Annual Epidemiological Report on listeriosis, published in March 2025:
- In 2023, 2,993 confirmed cases of listeriosis were reported in the EU/EEA — the highest annual figure since EU/EEA-wide surveillance began.
- The notification rate reached 0.67 cases per 100,000 population.
- The highest incidence is among people over 64 (2.2 cases per 100,000 population).
- Listeriosis has the highest hospitalization rate and case-fatality rate among zoonoses monitored in Europe.
The joint EFSA/ECDC One Health 2024 zoonoses report, published in December 2025, confirms this trend: more than 3,000 Listeria infections were recorded in 2024, of which around 70% required hospitalization, and one in twelve people died.
It is against this epidemiological backdrop that the European Commission adopted Regulation (EU) 2024/2895, published in the EU Official Journal on November 20, 2024, which entered into force on December 11, 2024, and applies to all food business operators from July 1, 2026.
Understanding the pathogen: why Listeria is particularly hard to control
Before looking at the regulatory changes, it’s essential to understand why Listeria monocytogenes poses specific challenges that other foodborne pathogens do not pose in the same way.
A psychrotrophic pathogen
Listeria monocytogenes is a psychrotrophic pathogen, able to multiply at refrigeration temperatures, including down to 0°C. This is a defining trait: maintaining the cold chain does not prevent its growth over a product’s shelf life.
This property is particularly critical for ready-to-eat (RTE) foods, consumed with no further heat treatment. A product that leaves the production facility with very low contamination levels can reach concerning concentrations by the end of its shelf life, if growth potential is not sufficiently controlled.
Persistence in the production environment
Listeria monocytogenes is a ubiquitous bacterium with an exceptional ability to persist in production environments. It can survive for months, even years, in drains, on equipment surfaces, and within biofilms resistant to standard cleaning and disinfection protocols.
This persistence explains why contamination in a plant is not an isolated event — it’s a risk that requires continuous, systematic monitoring.
What Regulation (EU) 2024/2895 changes
Closing the legislative gap
Regulation (EC) No. 2073/2005 sets the microbiological criteria applicable to food in the EU. However, it contained a significant gap: for category 1.2 RTE foods (those that allow the growth of Listeria monocytogenes), no criterion applied once the product had left the immediate control of the operator that produced it, in cases where that operator could not demonstrate that the 100 CFU/g limit would not be exceeded throughout the shelf life.
In practice, a manufacturer could demonstrate compliance at the time of shipment without being responsible for what happens throughout the product’s shelf life in the distribution chain.
Regulation (EU) 2024/2895 closes this gap.
The fundamental change
As of July 1, 2026, food safety compliance is no longer assessed at a single point in time. Manufacturers must demonstrate that their products remain safe throughout their entire shelf life, including during distribution and up until the use-by date.
The three product categories
Annex I of Regulation (EC) No. 2073/2005 distinguishes three categories of RTE foods:
- Category 1.1: RTE foods intended for infants or for special medical purposes: not detected in 25g throughout shelf life.
- Category 1.2: RTE foods that allow the growth of Listeria monocytogenes (other than 1.1): covered by the new requirements starting July 1.
- Category 1.3: RTE foods that do not allow the growth of Listeria monocytogenes: criterion ≤ 100 CFU/g throughout shelf life.
Automatic classification into category 1.3
Products are automatically classified as category 1.3 (not supporting growth) when they meet at least one of the following physicochemical conditions, defined in footnote 8 of Annex I:
- pH ≤ 4.4
- Water activity (aw) ≤ 0.92
- Combination: pH ≤ 5.0 and aw ≤ 0.94
- Shelf life of less than 5 days
Important point: other products may also be classified as category 1.3 subject to scientific justification, for example via challenge tests or predictive modeling. Products that do not meet these automatic thresholds are not necessarily category 1.2 if a study demonstrates that they do not support growth.
Two paths for category 1.2 products
For category 1.2 RTE foods, two paths are possible under the amended regulation. The applicable criterion depends entirely on the evidence the operator can provide:
With validated evidence
The operator can demonstrate, to the satisfaction of the competent authority, that Listeria monocytogenes will not exceed 100 CFU/g throughout the product’s shelf life.
In this case, the ≤ 100 CFU/g criterion applies throughout the shelf life.
Without validated evidence
The operator cannot provide this scientific demonstration. In this case, the strictest criterion applies: not detected in 25g, throughout the shelf life of the product placed on the market.
The fundamental change concerns scope: previously, the “not detected in 25g” requirement applied only while the product was under the manufacturer’s direct control. As of July 1, 2026, it applies throughout the shelf life, wherever the product is in the distribution chain.
Operational implications for operators
Shelf-life studies and challenge tests
Taking path A requires solid scientific evidence. The European Commission has published an updated guidance document (DG SANTE, December 2025), and the EU Reference Laboratory for Listeria monocytogenes (EURL Lm, hosted at ANSES) published an updated version of its technical guidance document (TGD) in February 2026, specifically addressing challenge tests and durability studies.
These studies must be designed to reflect unfavorable production and storage scenarios, factoring in temperature variability, handling practices, and the product’s intrinsic characteristics. Historical data alone is generally insufficient as validation evidence.
Environmental monitoring plan: review and reinforcement
The regulation reinforces the importance of systematic environmental monitoring in production plants, particularly in post-heat-treatment areas, where cross-contamination is most likely to occur. Sampling plans must be reviewed to ensure adequate coverage of critical points where Listeria monocytogenes can establish itself and persist.
Revising HACCP plans
Existing HACCP documentation must be revised to incorporate the requirement to control the risk through to the end of shelf life as a control point. Critical limits and corrective action procedures must reflect the new regulatory scope.
Building the evidence file
The European Commission’s updated guidance document and the EURL Lm’s TGD provide the technical framework for structuring the evidence files that competent authorities are entitled to request. Operators must ensure that their validation files are structured, traceable, and accessible.
The role of molecular detection in achieving compliance
The ability to meet these requirements depends directly on the quality, frequency, and speed of detection throughout the production and monitoring process.
The LoopDeetect method offers significant operational advantages for environmental monitoring and product control:
- Shorter result turnaround compared with conventional culture methods, enabling faster decision-making.
- High sensitivity to low contamination levels: critical for detecting Listeria monocytogenes before it reaches concerning concentrations.
- Ability to integrate into high-frequency routine monitoring plans, without disrupting production flows.
At Loop Dee Science, LoopDeetect reagents are designed for this type of routine, high-frequency molecular detection, providing reliable, traceable results within the timeframes required by environmental monitoring and industrial control programs.

Conclusion
Regulation (EU) 2024/2895 represents a structural change in how food safety responsibility is defined for RTE foods in the European Union. The compliance window is no longer limited to the production facility — it extends throughout the product’s entire commercial life.
For quality managers, site directors, and food safety teams, the practical implications are clear: shelf-life studies must be validated or revalidated, environmental monitoring plans must be reinforced, and HACCP documentation must be updated to reflect the new scope.
The deadline is set for July 1, 2026. The question today is no longer whether to act, but whether the evidence is already in place.
