Artificial phylloplanes: A novel tool to study parameters linked to bacterial and viral contamination of fresh produce
Every year, one-in-six Americans suffer from a food-related illness caused by bacteria, viruses, or parasites. Since 2010, fresh produce has been linked to seven foodborne outbreaks caused by Escherichia coli species alone. Produce surface properties, such as surface hydrophobicity and surface …

Detection and survival of Escherichia coli O157:H7 in cattle water troughs and the effects of cetylpyridinium chloride against Escherichia coli O157:H7 biofilms on the surface of stainless steel
Escherichia coli O157:H7 is an emerging food pathogen that was first identified as a cause of illness in 1982. According to CDC (The Center for Disease Control and Prevention) estimates, E. coli O157:H7 is responsible for about 73,000 illnesses, 2,000 hospitalizations and 60 deaths in the United …
