Summary

Join us for an insightful event exploring how to understand and tackle Listeria risks across the food chain — from good manufacturing and food processing practices to effective cleaning strategies and retail perspectives. We'll dive into outbreak and recall management, public health impact, and a real-world case study showcasing fast and insightful detection methods such as pathogen mapping and environmental monitoring expertise.

Who should attend

Designed for decision-makers across the food production chain – because Listeria management is everyone's business.

Provisional programme

Time Presentation
09:00 Registration and arrival refreshments
09:30 Welcome and Chairperson's introduction
09:45 Outbreak management and impact to public health
Anaïs Painset, UKHSA
10:25 Networking and refreshment break
10:45 Control of Listeria through formulation and process
Jeff Banks, Managing Consultant, Food Safety Assurance
11:25 How can we optimise source tracking for L. monocytogenes

12:00 Networking and lunch
13:00 Listeria – a retail perspective

This presentation will share the challenges with Listeria management from a retailer point of view, including the importance of approving and managing a strong base of partner suppliers, detailing how Listeria specifications are set, how results are monitored and out of specification results and incidents managed. Sarah will also share some of the Co-op’s next steps as part of the ever-evolving challenge to maintain product safety.

Sarah Dickinson, Co-op Group
13:40 Networking and refreshment break
14:00 Mapping Listeria spp. through ready-to-eat food production premises in Wales and the use of adaptive laboratory evolution to assess biocide-antibiotic cross-resistance
This presentation explores two components of Joshua’s PhD; the distribution of Listeria spp. within three ready-to-eat (RTE) food production premises in Wales and the development of an adaptive laboratory evolution (ALE) experiment to investigate biocide-antibiotic cross-resistance in environmentally derived Listeria spp. The findings suggest that stress-adapted, less virulent sequence types (STs) form persistent communities within facilities and centre around difficult-to-clean sites. These findings highlight the value of academia-industry collaborations in identifying and addressing Listeria contamination persistence. The ALE experiment revealed benzalkonium chloride-mediated cross-resistance to clinically pertinent antibiotics, with both phenotypic and genotypic evidence of adaptation.
Josh MacLeod, Cardiff Metropolitan University
14:40 What kills Listeria and how do you remove it?

“Managing Listeria through active hygiene”. This presentation will highlight strategic methods of decontaminating high hygiene areas through the effective use of cleaning agents as part of a 5 point control plan to manage Listeria.

David Childs, Kersia UK
15:20 Panel discussion: Listeria in transition - EU rules and the UK reality
16:00 Q&A and close

Speakers profiles coming soon

Anaïs Painset, UKHSA

Anaïs Painset is a Lead Bioinformatician for gastrointestinal pathogens at the UK Health Security Agency (UKHSA), formerly known as Public Health England. Since joining the organization in 2015, she has been instrumental in the implementation of whole genome sequencing (WGS) pipelines for gastrointestinal pathogens. Anaïs has extensive expertise in analysing WGS data to support pathogen surveillance and outbreak investigations, particularly through phylogenetic analysis. Her research interests include phylogenomic and gene profiling, with a focus on genotypic antimicrobial resistance (AMR) and virulence factors.

Jeff Banks, Managing Consultant, Food Safety Assurance

Dr. Jeff Banks is a food quality and safety professional with more than 45 years’ experience. He holds a degree in Applied Biology and a PhD in Food Microbiology. After academic work he become the Microbiology Department Head at Campden Food Research. He has deep knowledge and experience in all segments of the food processing sector. He has assessed or audited over 1200 plants in over 80 countries and claims to remember all of them. He has held senior leadership positions in R&D, Quality Assurance and Regulatory Affairs in global food business such as DuPont, Cadbury-Schweppes, Kraft Foods and Barry Callebaut. Jeff feels equally comfortable in the boardroom, on the plant floor or in courts of law.

He currently applies his knowledge to support clients in the food sector manage food safety and quality risks; ensure regulatory compliance and develop innovative solutions to complex technical challenges. He specialises in root cause analysis and incident management. He is an expert witness and has successfully applied his talents in legal cases in several countries for both defence and prosecution and in the International Court of Arbitration. He claims to have a 100% record of success - but still believes that prevention is much better than litigation. Over the years he has been sought out by businesses in crisis caused by microbes. Jeff has successfully resolved major microbiology incidents involving Salmonella, Listeria monocytogenes, and E. coli, typically during and after outbreaks of foodborne disease involving significant morbidity and mortality.

Most of the time, however, Jeff works in the shadows, without publicity - the unseen hand at work – preventing problems, avoiding withdrawals and recalls and de-risking the food supply chain.

As a footnote, he is a proud father of an even more famous microbiologist, Dr. Emma Banks, Royal Society Fellow 2023 based at the prestigious John Innes Institute in the UK.
