A study was conducted to investigate the effect of chilling method (air or immersion) on concentration and prevalence of Escherichia coli, coliforms, Campylobacter, and Salmonella recovered from broiler chicken carcasses. For each of four replications, 60 broilers were inoculated orally and intracloacally with 1 ml of a suspension containing Campylobacter at approximately 10(8) cells per ml. Af...

The bacterial succession on the skin of broiler chicken carcasses stored at 2 degrees C was traced, and the ability of representative isolates to produce off-odors was determined by using sterile leg and breast muscle sections. Off-odors were identified by olfactory and chemical means. The inability of peptone-iron agar to detect sulfide-producing strains was noted.

The aim of this study was to investigate the effects of the use of chlorine or ozone as sanitizing agents in the water of chicken immersion chilling, using the residual levels usually applied in Brazil (1.5 ppm), comparing the effects of these treatments on the microbiological, physicochemical, and sensory characteristics of carcasses. Chicken carcasses were chilled in water (4°C) with similar ...

Here, we present the draft genome sequences of nine multidrug-resistant Escherichia coli strains isolated from humans (n = 6) and chicken carcasses (n = 3) from Lagos, Nigeria, in 2013. Multiple extended-spectrum β-lactamase (ESBL) genes were identified in these isolates.

Transmission of Campylobacter to humans has been prominently associated with mishandling or improperly preparing contaminated poultry carcasses. The number of organisms per carcass represents an important measure of human exposure to the agent. Therefore, we wished to estimate this public exposure over 1 yr among Italian broiler carcasses. We sampled 213 broiler carcasses from rinse water sampl...

Incidents of foodborne illness associated with consuming undercooked or raw chicken are often linked to 2 causative pathogens: Campylobacter spp. or Salmonella spp. Numerous studies have shown that contamination of carcasses results when pathogens are transferred from the intestinal tract or fecal material on feet and feathers to the dressed carcass. Ultraviolet spectral imaging to detect surfa...

The draft genome sequence of Arcobacter cibarius strain LMG21996(T), isolated from chicken carcasses, is reported here. The draft genome consists of 2.2 Mbp, with a 27.12% G+C content. A total of 2,179 protein-coding genes, 46 tRNA genes, and 15 rRNAs have been identified and annotated.

listeria monocytogenes is an important food borne pathogen with a high case fatality rate. among 13 different serotypes of this bacterium, 4 serotypes (1/2a, 1/2b, 1/2c, and 4b) were considered as the main cause of listeriosis outbreaks. the aim of this study is to identify the major serotypes and virulence genes in listeria monocytegenes isolated from chicken carcasses which were collected fro...

A case of oviductal volvulus, a rare disorder with oviductal cyst as a possible aetiology, is described in an 11-month-old Nera black chicken (Gallus gallus domesticus). The condition was observed during routine postmortem examination of 550 carcasses from a flock of 16,100 birds between September 2005 and June 2006. The affected portion of the oviduct and the cyst twisted almost 360 degrees cl...

To assess post-evisceration contamination of broiler carcasses, 300 samples were randomly selected during routine slaughter in the winter of 2004. The samples originated from 50 chicken carcasses, taken directly after evisceration, as well as 25 samples from ready-to-sell packages of fresh intestines (mala) and livers. The samples were taken in batches over a period of 4 weeks to allow randomis...
