What comes to mind when you hear “contamination” in food factories?

For most people, it’s microbes. But there’s a bigger, tougher problem most don’t see: biofilms. These stubborn bacterial colonies are hard to remove and can lead to serious food safety issues.

In this episode of ‘Behind Clean Lines’, we talk with Debra Smith, a global hygiene specialist and microbiologist at Vikan. She breaks down what biofilms are, how they form, and why they’re such a challenge to food safety.

From a devastating listeria outbreak to critical cleaning practices, Deb shares real-world examples and practical advice to help protect your operations.

We’ll look at the essentials—like equipment design and cleaning processes—and how they play a essential role in fighting biofilms. You’ll also learn how to build a stronger food safety culture within your team.
