Cleaning and disinfection (C&D) is often an undervalued element of farm management but is vital for disease control and eradication, biosecurity and improvement of pre-harvest food safety. The aim of C&D is to remove organic matter, using physical andwater-based cleaning methods, and kill remaining microorganisms via chemical disinfection and desiccation (rest). If cleaning is ineffective at removing faeces there will be pathogen persistence and decreased effectiveness of disinfection. Biofilms arealso responsible for pathogen persistence; additionally, they can corrode metal, damage concrete and cause resistance to antimicrobials. Detergents can help to disrupt biofilms, assist with removal of organic matter and are bactericidal.
