The objective of this study was to determine the prevalence and antimicrobial resistance of Campylobacter spp. isolated from chicken carcasses during different stages of broiler processing in a major commercial poultry processing plant in southwestern Iran. Overall, 84 chicken carcasses were sampled from 4 sites along the processing line during a total of 7 visits. In addition, 14 water samples...

A study was conducted to investigate the effects of spray washing broiler carcasses with acidified electrolyzed oxidizing water (EO) or sodium hypochlorite (HOCl) solutions for 5, 10, or 15 s. Commercial broiler carcasses were contaminated with 0.1 g of broiler cecal contents inoculated with 10(5) cells of Campylobacter and 10(5) cells of nalidixic acid-resistant Salmonella. Numbers of bacteria...

The objective of this study was to develop a real-time PCR assay for rapid identification of Campylobacter jejuni and to apply the method in analyzing samples from poultry processing. A C. jejuni-specific primer set targeting a portion of the C. jejuni hippuricase gene was developed. The specificity of the newly designed primer pair was verified using 5 C. jejuni strains and 20 other bacterial ...

BACKGROUND Campylobacter is one of the leading bacterial species causing foodborne illnesses in humans. Antimicrobial agents have been extensively used for treatment of Campylobacter infections; but in the recent years, both animal and human isolates of this bacterium have shown resistance to several antibiotics such as tetracycline. OBJECTIVES The aim of this study was to investigate the pre...

Primary and further processing of poultry is a multibillion dollar industry in the US. The majority of poultry raised and commercially processed in the US is composed of chickens, turkeys, and ducks, with more than 9 billion birds processed in 2010 (Table 24.1). Total retail product weight exceeded 58 billion pounds, with an estimated retail value of $100 billion. The general process of turning...

Total or partial condemnation of carcasses in the slaughter houses has always been a major concern for the poultry industry as it represents huge economical losses for companies. In the United States of America, losses due to cellulitis, an inflammation of the subcutaneous tissue of broilers (usually contaminated with Escherichia coli), exceed 35 million USD per year. Combined with other losses...

twenty carcasses from a small flock of 5000 four-weeks old broiler chickens were submitted to a poultry disease diagnostic clinic in tehran. at necropsy, 19 carcasses showed the typical lesions of colibacillosis such as pericarditis, prihepatitis and airsaculitis. one case did not show any gross lesion of colibacillosis or chronic respiratory disease (crd) but the liver had an abnormal size con...
