54 distinct finishing barns were recruited for voluntary participation in this study. Each housed approximately 960 pigs. Therapeutic ceftiofur use in each barn was classified as ‘‘Rare,’’ ‘‘Moderate,’’ or ‘‘Common’’ (n = 18 barns for each) based on frequency of ceftiofur use reported by the veterinarians responsible for the health of the animals on these farms.Barns with ceftiofur use classified as Rare did not include ceftiofur in standard treatment protocols for common health problems such as respiratory disease, and it would be unusual for any of these pigs to receive therapy with ceftiofur. Barns with ceftiofur use classified as Moderate included ceftiofur as one of the therapeutic options in standard treatment protocols, although not as the first choice, and it would not be unusual for these pigs to receive therapy with ceftiofur although other drugs would be used more frequently. Barns with ceftiofur use classified as Common included ceftiofur as the therapy of choice in standard treatment protocols for common health conditions, and ceftiofur was the most frequently used therapy.

Frsh fecal samples were systematically collected from the floor of occupied pens during a single visit to each barn
