Rethinking Listeria monitoring: faster, simpler solutions for food safety & environmental testing

Listeria remains one of the most challenging pathogens for the food industry due to its ability to persist in production environments and survive under conditions that inhibit many other bacteria, including refrigeration and high-salt processing. Its association with severe illness and food recalls places ongoing pressure on manufacturers and laboratories to detect contamination quickly and reliably across both food and environmental samples.

This webinar will explore how Listeria monitoring solutions are evolving to meet these demands, particularly for laboratories balancing speed, cost and operational complexity. Traditional culture methods can delay critical decisions, while PCR and ELISA often require significant capital investment, infrastructure changes and specialist training, creating barriers for low to medium-throughput operations.

Using Solus NanoFast™ Listeria as a practical example, the session will demonstrate how alternatives to culture, PCR, and ELISA can support next-day detection through simplified workflows that reduce training requirements and infrastructure changes. The discussion will also highlight how automated result interpretation and digital data management can improve consistency, traceability and audit readiness.

During the session, you will learn how to:

• Address common challenges in food and environmental Listeria monitoring

• Evaluate cost-effective alternatives to culture, PCR, and ELISA for low to medium-throughput testing (up to ~50 samples/day)

• Improve turnaround times without increasing workflow complexity

• Support audit readiness through objective results and digital traceability

• Align Listeria testing strategies with operational and regulatory requirements
