FIG. 2.

Comparison of hide and preevisceration carcass sample enumeration data for Salmonella (CFU/100 cm²) with paired preevisceration carcass prevalence data. The data presented were collected on two different days at each of the four plants sampled (plant A [A1 and A2], plant B [B1 and B2], plant C [C1 and C2], and plant D [D1 and D2]). Samples were collected consecutively, and lot break information, when available, is indicated by gray dashed lines. The dark-gray bars and light-gray bars indicate enumerable hide and preevisceration carcass samples and the Salmonella loads in those samples, while the light-gray diamonds indicate preevisceration carcass samples that were positive for Salmonella by enrichment.
