Figure 3.

Surface contamination levels across 6 locations as measured by relative light units (RLU) with 3 independent ATP luminometers. Farrowing room locations include entryway floor, sow feeder, farrowing crate sorting bars, farrowing crate back wall, farrowing crate corner, and the piglet floor mat. ATP luminometers were novaLUM II-X (Charm Sciences, Lawrence, MA), 3M Clean Trace (Neogen Corporation, Lansing, MI), or Neogen AccuPoint (Neogen Corporation, Lansing, MI). Means within a luminometer that do not share a superscript differ (P ≤ 0.05).
