Technical Abstract: A study was conducted to determine external microbiology of genetically featherless broiler carcasses after forced cloacal fecal expulsion. Full-fed featherless broilers were placed into coops, transported, unloaded, shackled, stunned, suffocated, weighed and divided into three treatments groups. Carcasses were transferred to a separate shackle line and passed through a machine designed to induce defecation (squeeze) and then remove external feces (wash). Treatments were obtained by turning the squeezing and washing components on or off. Treatments were as follows: S carcasses were squeezed but not washed; W carcasses were not squeezed but were washed; and SW carcasses were squeezed and washed. Concentrations of total aerobic bacteria (AB), Escherichia coli (EC), coliforms (CF), and Campylobacter (CP) recovered from whole carcass rinses did not vary with treatment (P > 0.05); however, counts of Salmonella (SAL) in the rinses of S carcasses were 1.4 log10 cfu/mL greater than counts of SAL found in rinses of SW carcasses (P < 0.05). SAL prevalence was similar for S (86% positive), W (90% positive) and SW (83% positive) carcasses (P > 0.05). Populations of AB and CF recovered wash water for SW carcasses were significantly higher by 3.1 and 1.5 log10 cfu/mL, respectively than the populations of the same bacteria recovered from wash water from W carcasses (P < 0.05). Levels of EC and CP recovered from wash water did not vary with treatment. There was no difference in CP and SAL prevalence in water collected after washing W carcasses or SW carcasses (P > 0.05). Data from the present study show that controlled cloacal fecal explusion immediately after slaughter can be used to reduce carcass fecal material, and therefore could be used to minimize the likelihood of visible contamination and associated bacteria during subsequent processing steps.
