Chickens at selected points in the slaughter process and after slaughter on the dressing line in poultry plants were sampled and analyzed for Salmonella. These chickens came from the northeast part of Poland. The examinations were carried out in quarters I, II, III, and IV of 1999. All the birds were determined to be healthy by a veterinary inspection. Swab samples were taken from the cloaca after stunning and from the skin surface and body cavity of the whole bird after evisceration, after rinsing at the final rinse station but before chilling in the spin-chiller, and after cooling in the continuous cooling plant at the end of the production day. In 1999, 400 whole chickens were examined. The percentage of these 400 chickens from which Salmonella spp. were isolated was relatively high (23.75%; Salmonella-positive results were observed in 95 cases). Salmonella spp. were found after stunning in 6% of the chickens (6 of 100 samples), after evisceration in 24% (24 of 100), before cooling in 52% (52 of 100), and after cooling in 13% (13 of 100). These results show that Salmonella spp. were found more often at some processing points than at others. The lowest Salmonella spp. contamination rate (6%) for slaughter birds was found after stunning, and the highest contamination rate was found before chilling (52%). The serological types of Salmonella spp. isolated from whole chickens were Salmonella Enteritidis, Salmonella Typhimurium, Salmonella Saintpaul, Salmonella Agona, and Salmonella Infantis. The results of these investigations indicate that Salmonella Enteritidis is the dominant serological type in infections of slaughter chickens, as it is in many countries.

From January 1997 to May 1998, 772 samples of poultry carcasses and poultry products for sale on the retail market in Belgium were analyzed for the presence of Salmonella spp., Salmonella Enteritidis, Campylobacter jejuni, C. coli, and Listeria monocytogenes per 100 cm2 or 25 g. Poultry samples were contaminated with Salmonella (36.5%), C. jejuni and C. coli (28.5%), and L. monocytogenes (38.2%). In about 12.3% of the poultry samples, the L. monocytogenes contamination level exceeded 1 CFU per g or cm2. Significant differences in pathogen contamination rates of poultry products were noticed between the poultry products originating from Belgian, French, and U.K. abattoirs. Poultry products derived from broiler chickens running free in pine woods until slaughtering age (12 to 13 weeks) had a significantly (P < 0.05) lower contamination rate of Salmonella than poultry products from enclosed broilers slaughtered at the age of 6 to 8 weeks. A significantly (P < 0.05) lower pathogen contamination rate was noted for Salmonella, C. jejuni, and C. coli for poultry cuts without skin compared to poultry cuts with skin on. An increase in pathogen contamination rate was noticed during cutting and further processing. To diminish C. jejuni, C. coli, Salmonella, and L. monocytogenes contamination rates, hygienic rules of slaughter and meat processing must be rigorously observed. At the moment, zero tolerance for these pathogens is not feasible, and there is a need to establish criteria allowing these pathogens to be present at reasonable levels in the examined poultry samples.

Sixty-five samples of traditionally made fresh sausages obtained from retail shops and butcher shops in northem Greece were screened for the presence of Salmonella spp. and Listeria spp. Salmonella spp. were found in 20% of the samples tested (54% Salmonella typhimurium and 46% Salmonella enteritidis). The prevalence of Listeria spp. in the samples was 26% (12% Listeria monocytogenes, 76% Listeria innocua, and 12% Listeria welshimeri). Nine of 13 Salmonella isolates were found to be resistant to ampicillin and 4 of 13 showed intermediate sensitivity; 1 of 13 was found to be resistant to chloramphenicol and 1 of 13 to tetracycline. Two strains of Salmonella typhimurum were multiresistant (resistant to ampicillin, chloramphenicol, and norfloxacin). All Listeria isolates were sensitive to the antibacterial agents tested that are commonly used for the treatment of human listeriosis.

Abstract Turkeys carcasses at selected point after slaughter on dressing line in poultry were sampled and analyzed for Salmonella. These slaughter turkeys came from the northeast part of Poland. The examinations were carried out in each month of 2009. Three hundred turkeys were selected at random from a commercial slaughter line, immediately after completing the cooling process. The percentage of these 300 turkeys from which Salmonella spp. were isolated was relatively high (8.3%; Salmonella positive results were observed in 25 cases). The lowest Salmonella spp. rate (1.3 %) for slaughter birds was found in the fourth quarter, and the highest contamination rate at 18.6% was found, in the third quarter. The serological types of Salmonella spp. isolated from the whole turkey carcasses were S. Saintpaul, S. Senftenberg, S. Anatum, S. Heidelberg, S. Hadar, S. Typhimurium and S. Infantis.

El objetivo del presente estudio fue identificar mediante PCR múltiple la posible existencia de los serovares Salmonella Typhimurium y Enteritidis en 25 cepas de Salmonella spp previamente aisladas de cuyes e identificadas por sus características metabólicas. Mediante el análisis molecular se identificaron todas las cepas como Salmonella Typhimurium, evidenciando la amplificación de los cebadores específicos para los genes invA y fliC pertenecientes al género Salmonella y Salmonella Typhimurium, respectivamente. El presente estudio permitió establecer una metodología rápida para la identificación molecular de Salmonella Typhimurium y Enteritidis aislados de cuyes.

The aim of this study was to identify the serological types of Salmonella most frequently detected in broiler chicken meat from 22 retail stores in Warmian-Masurian Voivodeship. For the purposes of the study, 200 samples (wings, legs) were taken randomly from meat packed on trays and stored in chilling cabinets in retail stores. Salmonella in chicken meat was detected by a method recommended by the Veterinary Committee, and published in the Polish Standards (PN-EN ISO 6579:2003). Meat was contaminated with Salmonella in 9 (40.9%) out of 22 retail stores where samples were taken. Salmonella was present in 13 (6.5%) out of 200 samples tested. The following serological types were found: S. Enteritidis (76.92%), S. Infantis (15.38%), S. Virchow (7.69%). The serotypes detected in broiler chicken meat were those that occur most frequently in human food poisoning outbreaks in Poland. It is important to monitor the presence of Salmonella in chicken carcasses in retail stores to understand the actual hazard level and to reduce the risk of salmonellosis in humans. In Poland, as well as in other countries, there are no effective methods for the decontamination of chicken carcasses contaminated with Salmonella. A comparison of our results with those from previous studies on the presence of Salmonella in retail stores shows that positive results can be expected from the improvement of hygiene standards in hatcheries, poultry processing plants, and retail stores.

Salmonella enterica is one of the most common causes of foodborne illness worldwide. Contaminated poultry products, especially meat and eggs are the main sources of human salmonellosis. Thus, the aim of the present study was to determine prevalence, antimicrobial resistance profiles, virulence, and resistance genes of Salmonella Enteritidis (S. enteritidis) and Salmonella Typhimurium (S. Typhimurium) isolated from laying hens, table eggs, and humans, in Sharkia Governorate, Egypt. The antimicrobial activity of Biosynthesized Silver Nanoparticles (AgNPs) was also evaluated. Salmonella spp. were found in 19.3% of tested samples with laying hens having the highest isolation rate (33.1%). S. Enteritidis) (5.8%), and S. Typhimurium (2.8%) were the dominant serotypes. All isolates were ampicillin resistant (100%); however, none of the isolates were meropenem resistant. Multidrug-resistant (MDR) was detected in 83.8% of the isolates with a multiple antibiotic resistance index of 0.21 to 0.57. Most isolates (81.1%) had at least three virulence genes (sopB, stn, and hilA) and none of the isolates harbored the pefA gene; four resistance genes (blaTEM, tetA, nfsA, and nfsB) were detected in 56.8% of the examined isolates. The AgNPs biosynthesized by Aspergillus niveus exhibit an absorption peak at 420 nm with an average size of 27 nm. AgNPs had a minimum inhibitory concentration of 5 µg/mL against S. enteritidis and S. typhimurium isolates and a minimum bactericidal concentration of 6 and 8 µg/mL against S. enteritidis and S. typhimurium isolates, respectively. The bacterial growth and gene expression of S. enteritidis and S. typhimurium isolates treated with AgNPs were gradually decreased as storage time was increased. In conclusion, this study indicates that S. enteritidis and S. typhimurium isolated from laying hens, table eggs, and humans exhibits resistance to multiple antimicrobial classes. The biosynthesized AgNPs showed potential antimicrobial activity against MDR S. enteritidis and S. typhimurium isolates. However, studies to assess the antimicrobial effectiveness of the biosynthesized AgNPs in laying hen farms are warranted.

Breeder cows, cattle recently arrived at feedlots, and cattle about to be shipped for slaughter were tested for Salmonella spp. No Salmonella spp. were detected in fecal samples from breeding cows. Nineteen of 1,000 (1.9%) fecal samples from recently arrived feedlot cattle were positive for Salmonella spp. compared to only 2 of 1,000 (0.2%) fecal samples taken within 2 weeks of slaughter. The positive fecal samples were collected in 5 of 50 (10%) “recent arrival” pens tested and in 1 of 50 (2%) pens tested within 2 weeks of slaughter. The serotypes isolated were Salmonella Agona, Salmonella Enteritidis, Salmonella Typhimurium DT104, and Salmonella 4,5,12:i:−. Ground beef samples purchased from retail outlets throughout Alberta were processed for Salmonella spp. Thirteen of 1,002 (1.3%) samples were positive for Salmonella spp. The serotypes isolated from ground beef were Salmonella Anatum, Salmonella Heidelberg, Salmonella Montevideo, Salmonella Typhimurium, Salmonella Typhimurium var. Copenhagen, and Salmonella Rough-O:i:1,2. The antibiotic resistance and pulsed-field electrophoresis gel macrorestriction patterns of all isolates were compared.

The presence of Salmonella spp. in the diarrhoeic syndrome of 24 cases of calves, 36 cases of kids and 14 cases of lambs was investigated. Salmonella was isolated as the pathogenic agent from six herds of calves and four cases of kids. The identified species was Salmonella enteritidis in three herds of calves and two cases of kids. Salmonella typhimurium was identified in two herds of calves and one case of kids. Also, Salmonella abony and Salmonella cerro were identified in one case of calves and kids, respectively. Furthermore, Shigella hyodysenteriae was isolated from two cases of diarrhoeic syndrome in lambs. All the infected animals were characterized by persistent haemorrhagic diarrhoea and high mortality. The occurrence of Salmonella enteritidis in ruminants is probably an important point of the epidemiology of Salmonella spp. and may play a significant role in the public health.
