Listeria monocytogenes (L. monocytogenes) is a species of pathogenic (disease-causing) bacteria that can be found in moist environments, soil, water, decaying vegetation and animals, and can survive and even grow under refrigeration and other food preservation measures. When people eat food contaminated with L. monocytogenes, they may develop a disease called listeriosis. *

The severity of listeriosis varies and in some cases can be fatal, especially among the elderly, people with weakened immune systems or chronic diseases.

This was enough reason for our team to research the effectiveness of our QCE5® bacterial blends, against this notorious pathogen. The result? Yes, our bacteria eliminated the pathogen and a report of our research can be read here. 

How can we achieve this result on the production floor where Listeria causes the biggest risk of contaminating food products?

Listeria is very resistant to cleaning and cultures grow fast under harsh conditions. This is the main reason that traditional cleaning methods are not sufficient enough and this causes these outbreaks we see in the local news, when food is being called back.

Fighting Listeria with chemicals will only do so much. Listeria can contaminate porous concrete and hibernate deeply in a surface using strong biofilm made of polymers that Listeria produce. This way, they are protected from the chemicals.

The places are hard to reach and after cleaning, Listeria grows back to its original size or worse. But, we have good news. If Listeria grows on food and chemicals only disperse food particles, we need to fight Listeria at the source of its existence.

QCE5® is a natural enemy for Listeria and safe for humans and water. Breaking down these organic compounds quickly, until its no longer available for Listeria.

Bacteria work intelligently together, break the biofilm and complety overtake it´s environment. Our bacteria are the biggest eaters. For example; the non-GMO Bacillus Subtillis strain, eating organic compounds from the water until there is no more. The Listeria strain is outcompeted and overtaken by our consortia.
