Abstract : Microbiological studies in two large poultry processing plants showed that the total and the psychrotolerant counts on finished birds ranged from 5,000 to 100,000 and from 200 to 5,000 cells per sq. cm., respectively, depending on the plant, and time of day samples were taken. An approximate 2.5 fold gradual increase in the total and psychrotolerant counts occurred on finished birds during a day's operation. Line studies indicated that the total count on the skin of birds was highest after the defeathering procedure. The fresh water shower following evisceration and passage of the carcasses through the continuous ice water chiller lowered the total count to some extent, but the skin of finished birds always contained more bacteria (1.5 to 22 times as many) than the skin of live birds. The psychrotolerant counts, on the other hand, more than doubled during passage through the continuous chiller. Live birds, fresh water and ice were found to be the sources of psychrotolerant bacteria in the plants. Achromobacter, Pseudomonas and Flavobacterium were present in about equal numbers on finished birds, with Achromobacter prevailing on live birds and Pseudomonas preponderantly being added during processing.
