  1. Note: Concentrations that were below the level of quantification (LOQ) were designated “LOQ”. For this assay the LOQ was 5 ng/g. If no 5-hydroxyflunixin levels were detected, the sample was designated “NF”. Untreated, control pigs used to assess the potential for environmental contamination were designated (C)
