Abstract
Microorganisms shed into decontaminated air from arms and hands of four dairy plant workers were collected on plates of various selective media using a Casella sampler. Microorganisms selected for identification were representative of the types encountered. Of 256 microorganisms isolated, 55.5% were cocci, 41.4% were rods, and only 3.1% were yeasts. Thirteen species of cocci were identified. Those occurring most frequently were Sarcina flava, Peptococcus prevotii, Sarcina aurantiaca, Sarcina hansenii, and Staphylococcus epidermidis, in decreasing order, of frequency. Eighteen species of rods were observed. Those identified most frequently, in decreasing order, were: Alcaligenes marshallii, Alcaligenes bookeri, Pseudomonas synxantha, Pseudomonas iodinum, Pseudomonas aeruginosa, and Corynebacterium striatum.
