Comparing Biofilm Forming Potential Of Listeria Species On Non-Food And Food-Contact Surfaces Of Importance To The Dairy Industry, Hannah Cooper
The Journal of Undergraduate Research
Listeria monocytogenes (Lm) is a foodborne pathogen of major safety concerns. This bacterium can resist/adapt to environmental stressors and persist through forming robust biofilms despite dairy plants following stringent surface cleaning protocols. Surface roughness is considered a major factor controlling bacterial attachment and biofilm formation. Food contact surfaces like stainless steel (SS) have low surface roughness for easy cleaning. On the other hand, non-contact surfaces like floors need a rougher surface to ensure employee safety. Hence, we hypothesized that Listeria biofilm formation would be lower on stainless steel compared to clay brick (CB; common flooring material in dairy plants). …
