Abstract
Two housed, swine-growing-finishing units were studied for numbers of total bacteria, fecal coliforms,
Staphylococcus
, and
Salmonella
in the air. At 30.5 and 122 cm from the floor, total colony-forming particles, as tested, averaged 3.4 × 10
5
and 1.3 × 10

/m
3
of air, respectively; whereas fecal coliform counts averaged 24 × 10

and 1.9 × 10
3
/m
3
of air, respectively. Only 41% of the organisms growing on
Staphylococcus
110 medium tested as
Staphylococcus
. Of 458
Staphylococcus
isolates, 5 were coagulase-positive. No
Salmonella
were detected in the air of the units tested.
