This study was designed to assess the survivability of porcine epidemic diarrhea virus (PEDV) in fomites and determine the efficacy of four commonly used disinfectants against the three swine enteric coronaviruses; porcine epidemic diarrhea virus (PEDV), porcine delta coronavirus (PDCoV) and transmissible gastroenteritis virus (TGEV). The fomites tested included Styrofoam, nitrile disposable gloves, cardboard, aluminum foil, cloth and Tyvek coveralls. Survivability was evaluated for 15 days at both room temperature and 4C. The disinfectants tested were: Synergize, Virkon-S, DC&R, and Tek-Trol. The virucidal evaluation of disinfectants was done by two test namely, the suspension test and surface test. The results showed that PEDV could be viable at 4C for 10 days in nitrile gloves, cardboard, aluminum foil and cloth, while it remained viable for 15 days in Styrofoam and Tyvek coveralls. In contrast, at room temperature survivability was significantly reduced to 2 days for all the materials. In addition, the results on disinfectants showed that TGEV was the most sensitive and PDCoV was the least sensitive to the disinfectants tested. For PEDV, DC&R was the most effective killing 3 log10 of the virus within 30 seconds in both tests.
