Critical Challenges in Food Production

The toughest contamination problems in food production are the ones traditional methods couldn’t fully solve—like Listeria and biofilms. Spectral Blue MWHI® targets these persistent risks with continuous blue light disinfection in the areas where it’s needed most.

The most unwanted

Listeria and Salmonella

Listeria and Salmonella were the most common biological causes of product recalls in the USA 2002-2023 (DeBeer et al, 2024).

A single Listeria recall can cost hundreds of thousands to several million euros or dollars.

Automated and continuous blue light disinfection can keep the production areas clean 24/7, without danger to staff.

Shelf-Life Saboteurs

Molds

Molds can reduce the shelf life of many foods, by causing visible growth and producing toxins.

Spectral Blue used continuously in the production and storage areas can eliminate airborne and surface-dwelling molds to extend shelf life and reduce visible spoilage.

The Hidden Survivors

Biofilms

Daily washing with water creates good conditions for microbes to develop biofilms - the silent disruptors of your hygiene program.

Biofilms can survive conventional cleaning and disinfectants. Spectral Blue can penetrate the protective layer and eliminate the colonies within.

Safeguarding Animal Health, Securing Food Safety

Infection control at farms

Animal diseases such as avian influenza can cause disruptions in food production.

Deploying Spectral Blue in cut-off rooms at animal shelters reduces the risk of pathogens entering.
