From today – 1st July 2026 - UK food businesses, especially those in the ready to eat sector, face greater Export EU regulations around Listeria.
The changes represent a significant shift in food safety expectations - not just regulatory but also strategic, affecting how products are formulated, tested, manufactured and shipped.
For those businesses still catching up with the new legislation—a significant risk in itself—the focus should not only be on products and processes, but also on the factory environment. Effective Listeria control starts with understanding how the building fabric, flooring systems and hygienic design can either support or prevent bacterial harbourage.
Commercial flooring and hygienic building fabric specialist Dave Sleight of Kemtile has been working with food and beverage manufacturers throughout the year to help them prepare for the changes. He commented:
"If they haven't already done so, businesses should be treating this regulatory tightening as a comprehensive Listeria risk review rather than simply a specification change. The focus must extend beyond products and processes to include flooring, drainage, hygienic detailing and the overall condition of the building fabric. Identifying and eliminating potential harbourage points is critical to reducing risk and demonstrating compliance."
1. Identify the highest-risk production areas
Review where ready-to-eat, chilled, high-moisture and long shelf-life products are manufactured. These areas should be prioritised for infrastructure assessments, as any environmental contamination poses a direct risk to product safety.
2. Assess the condition of floors and building fabric
Damaged flooring, failed joints, cracked surfaces, deteriorated coving and poor floor-to-wall interfaces can create ideal harbourage points for Listeria. A detailed survey should identify areas where water, debris and bacteria may accumulate beyond the reach of routine cleaning.
3. Review drainage performance
Drainage systems are often overlooked but can become a significant source of contamination. Assess whether drains are correctly positioned, adequately sized and easy to clean. Standing water, poor falls and damaged channels can all contribute to bacterial growth and spread.
4. Strengthen environmental monitoring around infrastructure
Environmental monitoring programmes should include known risk areas such as drains, floor joints, wall interfaces, service penetrations and areas prone to water ingress. Trending positive results can often identify underlying building fabric issues before they become a product contamination event.
5. Evaluate hygienic design principles
Older facilities frequently contain hidden Listeria harbourage points. Review flooring systems, kerbing, drainage details, equipment interfaces and cleaning access. Hygienic design should eliminate dead spaces, moisture traps and inaccessible areas where bacteria can survive.
6. Control water and moisture
Listeria thrives in wet environments. Persistent standing water, condensation, leaking services and moisture trapped beneath damaged flooring systems can create conditions for bacterial survival. Effective moisture management should be a key part of any Listeria control strategy.
7. Support HACCP with infrastructure controls
HACCP reviews should consider the impact of building fabric and flooring condition on contamination risk. Documented control measures should include inspection regimes, planned maintenance and corrective actions for flooring, drainage and hygienic detailing.
8. Prioritise refurbishment of high-risk areas
Where surveys identify deteriorated floors, failed drainage or damaged hygienic details, businesses should prioritise refurbishment based on risk. Investing in infrastructure improvements can significantly reduce environmental contamination risks and support long-term compliance.
9. Prepare for increased scrutiny
Retailers, auditors and regulators are increasingly focusing on environmental controls and hygienic design. Businesses should be prepared to demonstrate how flooring, drainage and building fabric are inspected, maintained and improved to minimise Listeria risk.
10. Train teams to recognise infrastructure risks
Production, engineering and hygiene teams should understand how damaged floors, failed joints, standing water and poor drainage contribute to contamination risks. Early identification and reporting of defects can prevent minor issues developing into significant food safety concerns.
In Summary
While environmental monitoring, product testing and shelf-life validation remain essential, many persistent Listeria issues originate within the factory infrastructure itself. Damaged flooring, failed joints, poor drainage and inadequate hygienic detailing can create hidden reservoirs for contamination.
One of the most effective actions businesses can take today is to assess the condition of their flooring, drainage and building fabric, identify potential harbourage points and address the highest-risk areas before they become a food safety issue.
In summary while starting early would have spread the costs and reduced disruption, today (1st July) businesses who are not prepared need to act. The most effective immediate action is to identify affected SKUs, rank them by listeria risk, review whether shelf-life evidence would withstand retailer or regulator challenge today and fix the highest-risk gaps first.
