The effect of acidic, electrolyzed oxidizing (EO) water and chlorinated water on the spoilage microflora of processed broiler carcasses was examined. Carcasses were sprayed for 5 s at 80 psi with tap, chlorinated, or EO water in an inside-outside bird washer. Treated carcasses were then stored at 4 degrees C for 0, 3, 7, or 14 d, and the microbial flora of the carcasses was sampled using the wh...

Experiments were conducted to determine the effect of prechill trisodium phosphate (TSP) treatment on reducing salmonellae recovery from broiler carcasses immediately after chilling or following 7 d of storage. Carcasses were sampled for salmonellae using whole carcass enrichment for 24 h at 37 degrees C. In each of 7 trials, 40 carcasses were obtained from a commercial processing plant. Batche...

Effects of spray washing carcasses with Lauric Acid (LA)-Potassium Hydroxide (KOH) on bacteria recovered from Whole-Carcass Rinsates (WCR) were examined. Carcass skin was inoculated with antibiotic resistant strains of Escherichia coli, Salmonella Typhimirum and Campylobacter coli. The first trial examined effects of washing carcasses with water, 0.25% LA-0.125% KOH, 0.50% LA-0.25% KOH, 1.00% L...

The bactericidal effect of mixtures of KOH and lauric acid (LA) on the microflora of broiler carcasses was examined. Carcasses were washed by shaking in KOH-LA for 1 min on a mechanical shaker. In one set of experiments, the population of bacteria recovered from carcasses following each of 3 successive washes in 1.0% KOH-2.0% LA or in distilled water (control) was enumerated. The number of tota...

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 3 treatments groups. Carcasses were transferred to a separate shackle line and passed through a machine designed to induce ...

This study was conducted to determine the effectiveness of the SmartMV prototype BeefCam Video Imaging System (prototype BeefCam) for classifying beef carcasses into palatability ("certified" or "not certified" as palatable) groups. Carcasses (n = 769) were selected from four beef-packing plants to represent three USDA quality grade groups (Top Choice, TC; Low Choice, LC; and Select, SE). Follo...

Genetically feathered and featherless sibling broilers selected for matched BW were killed, scalded, and defeathered to determine the consequences of feathers and empty feather follicles on the recovery of bacteria from carcass breast skin. In trial 1, the vents of all carcasses were plugged and sutured before scalding to prevent the expulsion of cloacal contents during picking. In trial 2, hal...

this study was conducted to investigate the bacterial contamination of small ruminant carcasses in traditional slaughterhouses of tehran province, in summer and winter seasons. 30 sheep and goat carcasses from slaughterhouses of rey, shahreyar and eslamshahr were evaluated. در انتهای خط کشتار و قبل از مرحله توزیع، از لاشه دامها نمونه برداری شد. randomly samples were taken at the end of the slau...

The current experiment was conducted to evaluate the on-line application of visible and near-infrared spectroscopy (VISNIR) to US Select carcasses during commercial beef carcass grading procedures to predict tenderness of longissimus steaks after 14 days of refrigerated storage. A regression model was calibrated using 146 carcasses and tested against an additional 146 carcasses. Carcasses were ...

this study was conducted to determine the prevalence of salmonellae contamination of chicken carcasses in slaughterhouses in central iran (yazd province). 435 samples were obtained from liver, breast— before and after chilling—and bacteriological and serological examinations were done. the results showed that the rate of contamination of liver, breast meat—before and after chiller—were 8.1, 18....
