About This Project

Listeria, salmonella, campylobacter, E.coli and other microbial contaminations are an ever-present threat on food processing surfaces. Food contamination is a public health issue, and food recalls are a significant economic issue. In 2014, the Rapid Alert System for Food and Feed (RASFF) transmitted a total of 3,157 food recall notices and public health warnings, an increase of more than 25% compared to 2013. The average cost of a recall to a food company is €10M in direct costs, in addition to brand damage and lost sales.


Most antimicrobial coatings rely upon a relatively simple but flawed premise: a toxic active ingredient, such as silver, copper or zinc, is impregnated into the coating. leaching out to contact and kill germs. This means the store of the chemical that provides the antimicrobial action is relatively quickly depleted. In addition, this leaching of toxic chemistry has negative implications for the aquatic environment, food safety, and human and animal health.


Exigence SymbiCoat™ is a breakthrough technology for unparalleled antimicrobial efficacy on hard surfaces. SymbiCoat™ represents a fundamentally different approach for creating materials which can prevent pathogens from surviving on a surface.SymbiCoat™ chemistry modifies existing coating materials (vinyls, epoxies, polyurethanes and others) through a method that does not contain a disinfecting chemical or active ingredient. Instead, SymbiCoat™ rapidly binds ECHA (European Chemical Agency)-registered chlorine bleach into ‘receptors’ in the coating. Chlorine bleach is one of the most widely used, cost-effective and well understood disinfectant chemicals available globally. SymbiCoat™ allows the chlorine bleach to provide a much longer period of action than would otherwise be possible, even at levels that are safe for food contact. SymbiCoat™ has the potential to radically enhance the contamination control in the food industry, helping prevent the spread of resistant bacteria and foodborne diseases.
