    Abstract

    The study examined and compared levels of aerial contamination in commercial beef and sheep plants at four sites, i.e. lairage, hide/fleece pulling, evisceration and chilling. Aerial contaminationwas determined by impaction and sedimentation onto Plate Count Agar to enumerate Total Viable Counts, MacConkey Agar to enumerate coliforms and Violate Red Bile Glucose Agar to enumerate Enterobacteriaceae. The levels of aerial contamination were similar at equivalent sites in beef and sheep plants, irrespective of the samplingmethod or the type of organisms recovered. Mean log counts recovered on each medium in the chillers were generally significantly lower (P
