Listeria completely eliminated in groundbreaking RTE food production pilot

* Listeria.jpgAll traces of listeria spp in a highly sensitive food production environment have been successfully eliminated in a breakthrough new pilot, undertaken by Bio-Fence.

The 11-week proof of concept saw Bio-Fence antimicrobial coatings applied to the floor and lower part of walls of a hotdog peeling room in a major sausage manufacturing facility in Israel. Despite repeated, strict cleaning and disinfection routines, the facility had a continuous pre-pilot presence of listeria sp, particularly on the production floor.

During the three-week control phase prior to the application of the Bio-Fence coating, listeria was detected in 21 out of 23 (91%) daily floor samples; following the application of the Bio-Fence coating, listeria was completely undetectable on the floor surface during day-to-day production*.

Results from the pilot also show a dramatic reduction of up to 99.9999% in the level of gram-negative bacteria as demonstrated by Enterobacteria (EB) readings, and a considerably improvement in hygiene levels as demonstrated by Total Count (TC) readings. Exactly the same cleaning and hygiene routines, involving a chlorine-based product, were practiced before and after the Bio Fence application.

Environmental pathogens within the food production process remains one of the greatest risks to food safety, with the presence of these bacteria in the production environment directly linked to the contamination of food.

The hotdog peeling room was specifically selected for the pilot as it poses a series of complex challenges to maintaining hygiene levels; the production environment includes low temperatures, humidity, condensation and heavy movement of workers and equipment - all conditions under which listeria can thrive.

Despite the pilot taking place under heavy organic load and wet conditions, the results demonstrate that Bio-Fence technology, when embedded in an industrial topcoat, can serve as a powerful anti-microbial solution that stabilises and prolongs the activity of standard sanitisers, thereby helping dramatically reduce the spread of listeria.

* LISTERIA-ELIMINATED.jpgAs a result of the successful proof of concept, the manufacturing facility has continued to use Bio-Fence's antimicrobial coatings and is now looking to expand the use of the coating in other areas of the facility.

*Positive post-application listeria results were established on one weekend during the trial, as chlorine was not used in that weekend's sanitation.

"Dealing with environmental pathogens like listeria, salmonella and others in food production processes is a continuous struggle for food manufacturers, especially in the production of sensitive food defined as RTE,” explains Ofer Shoham, CEO of Bio-Fence.

"There is a direct link between the presence of these bacteria in the immediate environment of production equipment and the contamination of food products. Sadly, thousands of people are still infected by listeria every year, causing a mortality rate of more than 25%.

"We are hugely encouraged by the breakthrough results of this pilot, which independently demonstrates the efficacy of the Bio-Fence product in helping eliminate listeria. We are convinced, as demonstrated by the POC results, that our technology can cut the path of infection and improve the overall hygiene level in food production.

"We look forward to using this trial as a basis to employ our product and technology into other highly sensitive food production environments."

Bio-Fence is an Israeli health and food tech start-up, founded in early 2018 at The Kitchen Hub, Israel's largest food tech incubator. Bio-Fence develops antimicrobial coatings and paints to destroy micro-organisms on contact and create a contamination-free environment. Bio-Fence's unique polymer is added to a topcoat that is then applied to surfaces. When disinfectant is applied to the surface as part of a routine cleaning process, the bio-fence technology stabilises the disinfectant onto the surface for an extended period of time, ensuring an elevated level of sanitisation.
