dc.description.abstractWe evaluated four surfaces [stainless steel, Delrin® (DuPont) acetal resin, fiberglass reinforced plastic wall paneling (FRP), and mortar] to determine the effects that surface-type, soil (porcine serum), and temperature (4ºC and 10ºC) have on the survival of Listeria monocytogenes, Salmonella spp., and Yersinia enterocolitica, in the presence of condensate. Mortar had the most lethality among the four surfaces studied with Listeria and Salmonella surviving better than Yersinia. Temperature had little effect on survival of all three organisms across all surfaces. However, Yersinia displayed growth on FRP at 10ºC, but death at 4ºC. Serum had a protective effect on L. monocytogenes on all four surfaces, with populations sustained at significantly (P ≤ 0.05) higher numbers over time than unsoiled coupons. Serum did not have an effect on the survival of Salmonella or Yersinia on stainless steel, acetal resin, or FRP, yet showed a protective effect on mortar.
