Despite evaluating a feed sample for 14 feed mills for 16 weeks, there was no detection of PRRSV, PEDV, PDCoV, and TGEV in any of the 224 collected feed samples. These results do not disprove that feed can be a fomite of domestic and foreign animal diseases. However, these findings are the first known evaluation of infected feed prevalence. The goal of this project was to provide a data point for pork producers to evaluate the actual risk of feed being a fomite of PRRSV, PEDV, PDCoV, and TGEV and what the return over investment scenarios are for using the various feed mitigants and sanitation products available today.
