Location: Foreign Animal Disease Research
Project Number: 1940-32000-057-46
Start Date: Dec 15, 2012
End Date: Dec 15, 2014
Development of surface disinfection methodologies would be variable due to surface properties (metal, concrete, rubber) and viral consentration and temperature. Foreign animal disease (FAD) viruses Foot-and-Mouth Disease (FMD), Classical Swine Fever (CSF) and African Swine Fever (ASF) would be used as model agents, dried on stainless steel, plastic and wood surfaces and disinfection efficacy of selected chemicals determined. Data will be generated for dose-response, timecourse and requirements for completion of disinfection. Once the above methodologies have been determined for use with standardized chemical disinfectants, commercial disinfectants identified by pork producers will be tested in the assays. Once an effective neutralization plan is developed for the targed disinfectants, efficacy data will be generated for each disinfectant on all three viruses on dried surfaces. Potential surrogates for FMDV, ASFV and CSFV will be identified in collaboration with the pork board. Side-by-side comparative disinfectant efficacy tests will be conducted with each FAD virus/surrogate pair. Once validated, these surrogates can be used outside high containment as needed to test newly formulated disinfectants.
