Listeria monocytogenes is facing increased scrutiny as new EU rules reshape how
ready-to-eat foods are assessed for safety.

The European Commission has published Regulation (EU) 2024/2895, introducing tougher controls for ready-to-eat foods.

From July 2026, businesses will need robust scientific evidence to prove their products remain safe throughout their entire shelf life, marking a significant shift in compliance expectations.

Why is Listeria Under Increased Scrutiny?

Listeria differs from many other foodborne bacteria. 

  • It survives in aerobic & anaerobic conditions. 
  • It can grow at refrigeration temperatures. 

The second point is particularly significant, as it means that where a product supports growth, listeria levels can increase during chilled storage. This could be in a depot, retail environment, or a consumer’s home. 

A Change in EU Regulations 

For ready-to-eat foods that support the growth of Listeria monocytogenes, businesses typically demonstrate “absence in 25g” at the point of production. After this stage, many rely on the ≤ 100 cfu/g limit to remain compliant during shelf life. Historical data and finished product testing are often used to support this approach. 

From July 2026, “absence in 25g” will become the default requirement for the entire shelf life of products that support growth. The 100 cfu/g limit will only be permitted where a business can scientifically demonstrate that this level will not be exceeded at any point before the end date. 

If growth cannot be ruled out through robust evidence, “absence in 25g” will need to be maintained throughout shelf life. 

What Does This Mean for the UK? 

Great Britain 

Following Brexit, new EU rules do not automatically apply in England, Scotland, or Wales. If you only supply the domestic GB market, you are not currently legally bound by the July 2026 update.

The Food Standards Agency has not confirmed that these changes will be formally adopted into GB law. However, the UK often aligns with EU food safety standards, so it is wise to stay informed and plan ahead.

Exporting to the EU 

If your site exports ready-to-eat foods to the EU or Northern Ireland, you must comply with the EU regulations. This is because authorities will assess your products against EU law, regardless of where they were made.

For many UK manufacturers, this makes preparation unavoidable. Even if your primary market is Great Britain, planning now will reduce risk and ensure compliance if your products cross borders.

Northern Ireland

Northern Ireland operates under the Windsor Framework, which keeps certain EU food safety laws in place. The new Listeria rules will apply from 1 July 2026. 

Which Products Will This Change Affect? 

The stricter requirements primarily focus on chilled ready-to-eat foods that can support the growth of Listeria monocytogenes. These include: 

  • Cooked sliced meats and pâtés 
  • Cold-smoked fish 
  • Soft cheeses 
  • Prepared salads 
  • Sandwiches and other chilled foods with multiple components  

If a product is eaten without further cooking and does not have strong intrinsic barriers, such as low pH or low water activity, it is likely to fall into this category. Where growth cannot be confidently ruled out, regulators will assume it can occur. This means the default expectation will be “absence in 25g” throughout the shelf life. 

Practical Steps to Consider 

If you produce chilled ready-to-eat foods, practical next steps include: 

  • Assess whether your shelf-life evidence is strong enough 
  • Strengthen environmental monitoring in higher-risk areas 
  • Clarify responsibilities across the supply chain 
  • Train teams and ensure all actions are fully documented 

A proactive, science-based approach will help protect consumers, maintain compliance, and demonstrate safety right through to the end of shelf life. 

A Note on Environmental Monitoring 

Even though demonstrating absence at the point of production is no longer enough on its own, listeria control during production is still a critical step in reducing contamination risk and maintaining good hygiene practices.

Klipspringer Listeria Isolation Swabs can help with this. They have been developed to support applications such as checking food contact surfaces, validating cleaning procedures, and identifying potential contamination points.

Quick and easy to use, these tests support a proactive hygiene strategy and help teams act swiftly if Listeria is detected.

Listeria control is no longer just about passing the right tests at the point of production. For UK businesses supplying Northern Ireland or exporting to the EU, you need to demonstrate safety throughout shelf life.
