Using foggers in supply entry rooms for decontamination of fomites entering sow farms to mitigate risk is a common practice. However, recent research questions the efficacy of this method for pathogen inactivation, especially in complex situations where pathogens may be shielded by organic material or blind spots.
In this study on time and temperature required for virus inactivation surfaces included diamond plate aluminum and cardboard tested at four temperatures with six holding times.
