“…In the farming of birds; rodents are a significant source of Salmonella infection (Carrique-Mas et al, 2009).According to the research, the introduction of flocks infected with Salmonella may cause transmission in rodents, which becomes a source of the microbe for subsequent flocks and creates a challenging challenge (de Freitas Neto et al,2009).The differences in frequency between farms may be explained by the sanitary practices used in each farm, the housing arrangement, the water source, the location of the sample, the season, the addition of antibiotics, and the health of the flock. The antibiotic susceptibility of the Salmonella strains was assessed in this investigation.…”

The ostrich meat is considered healthy as it contains low cholesterol and fat levels. Foodborne diseases caused by the bacterium Salmonellaare a significant public health concern. The study was conducted to determine the prevalence, the risk factors involved, and antimicrobial susceptibility patterns of Salmonella isolates recovered from captive ostrich feces in the district of Lahore, Pakistan. There is not a single research on this issue in Pakistan up to date in ostrich. A total of 100 ostrich fecal samples were collected- and specifically cultured on Salmonella Shigella agar. The antimicrobial susceptibility was checked for different antibiotics throughthe Kirby-Bauer disc diffusion method. The 21% fecal samples were found positive for Salmonella. The disease was found to besignificantly(p<0.05) associated with risk factors; water type(p=0.027), bird’s capacity(p=0.042), cage hygiene(p=0.024), age of bird(p=0.041) andother bird species around (p=0.031) while enclosure size and diet were found non-significant. The bacterium was found highly susceptible to Amoxicillin followed by Chloramphenicol, Gentamicin, Cefotaxime, andEnrofloxacin respectively.Further Salmonella species-level diagnostic studies along with susceptibility checks of more therapeutic agents are suggested to future researchers.

“…In previous studies Salmonella was isolated from grey langur [20], hyena [21], leopard [22], golden pheasants [23] and ostrich [24]. The isolation rate of Salmonella from the feces of all captive wildlife was 3.1% and by direct PCR assay, detection rate was found to be 5.7%.…”

Occurrence, antimicrobial susceptibility patterns and genotypic relatedness of Salmonella spp. isolates from captive wildlife, their caretakers, feed and water in India

Occurrence of Salmonella spp. in captive wild animal species in India is largely unknown. The purpose of this study was to determine the occurrence of different Salmonella serotypes, antimicrobial resistance patterns and genotypic relatedness of recovered isolates. A total of 370 samples including faecal (n = 314), feed and water (n = 26) and caretakers stool swabs (n = 30) were collected from 40 different wild animal species in captivity, their caretakers, feed and water in four zoological gardens and wildlife enclosures in India. Salmonellae were isolated using conventional culture methods and tested for antimicrobial susceptibility with the Kirby-Bauer disc diffusion method. Salmonella isolates were serotyped and genotyping was performed using enterobacterial repetitive intergenic consensus (ERIC) PCR and 16S rRNA sequencing. Animal faecal samples were also subjected to direct PCR assay. Salmonella was detected in 10 of 314 (3.1%) faecal samples by isolation and 18 of 314 (5.7%) samples by direct PCR assay; one of 26 (3.8%) feed and water samples and five of 30 (16.7%) caretakers stool swabs by isolation. Salmonella was more commonly isolated in faecal samples from golden pheasants (25%; 2/8) and leopard (10%; 2/20). Salmonella enterica serotypes of known public health significance including S. Typhimurium (37.5%; 6/14), S. Kentucky (28.5%; 4/14) and S. Enteritidis (14.3%; 2/14) were identified. While the majority of the Salmonella isolates were pan-susceptible to the commonly used antibiotics. Seven (43.7%; 7/16) of the isolates were resistant to at least one antibiotic and one isolate each among them exhibited penta and tetra multidrug-resistant types. Three S. Kentucky serotype were identified in a same golden pheasants cage, two from the birds and one from the feed. This serotype was also isolated from its caretaker. Similarly, one isolate each of S. Typhimurium were recovered from ostrich and its caretaker. These isolates were found to be clonally related suggesting that wildlife may serve as reservoir for infections to humans and vice versa. These results emphasise the transmission of Salmonella among hosts via environmental contamination of feces to workers, visitors and other wildlife.

“…The same applies to turkeys, but S. Enteritidis is very rare in turkey flocks and Salmonella from turkeys is considered to contribute little to human infection (EFSA BIOHAZ Panel, 2012;EFSA and ECDC, 2014). Ostriches are normally housed outdoors, and Salmonella has been occasionally reported in flocks (de Freitas Neto et al, 2009;Akbarmehr, 2010).…”

Salmonella Enteritidis is considered the only pathogen currently posing a major risk of egg-borne diseases in the European Union (EU). The possible impact of extending the shelf-life of eggs on the risk to consumers posed by S. Enteritidis was estimated by applying a quantitative model and comparing the actual situation regarding the storage of eggs in the EU with different possible scenarios combined, considering the prolongation of the bestbefore and the sell-by date from 7 to a maximum of 70 days. Extending the sell-by date by one week (from 21 to 28 days), but leaving the best-before date unchanged, is estimated to result in a relative risk of illness of 1.4 and 1.5 for uncooked and lightly cooked egg meals respectively, compared to the current situation. If the best-before date is also extended by one week (from 28 to 35 days), the relative risk would be 1.6 and 1.7. In the worst case scenario considered (sell-by date of 42 days, best before date of 70 days), such figures would be 2.9 and 3.5. It should be noted that the absolute risk is greater for uncooked meals compared to lightly cooked meals. An effective way to minimise any increase in risk during extended storage is to keep the eggs refrigerated both at retail and the household. Regarding egg spoilage, such events strongly depend on the hygienic conditions of egg production and practices of egg handling, including storage times and temperatures. Finally, the impact of the prolongation of storage time on the quality criteria for eggs (3-hydroxybutyric acid and lactic acid) destined for manufacturing of egg products is considered negligible. Specifically, EFSA was asked to assess: (i) the public health risk posed by relevant pathogens and in particular by Salmonella in the consumption and handling of table eggs (Term of Reference, or ToR1), (ii) the public health risk deriving from deterioration (ToR2) and (iii) possible consequences for public health of an extended shelf-life of table eggs for the specific freshness criteria for egg products as laid out in the hygiene package (ToR3). © European Food Safety Authority, 2014 KEY WORDSIn order to answer the first ToR, the BIOHAZ Panel based its conclusions on the results of a quantitative model, aimed at describing the behaviour of Salmonella Enteritidis following vertical transmission, since this serovar is recognised to be the major pathogen related to egg-borne disease because of its ability to contaminate the interior of intact eggs during their formation within the body of an infected hen. The possible impact of extending the shelf-life of eggs on other serovars of Salmonella, as well as on other pathogens, is evaluated in a qualitative manner, with no individual serovar other than S. Enteritidis currently posing a major risk of egg-borne salmonellosis in the European Union (EU), although S. Typhimurium has been associated with relatively small outbreaks due to duck eggs. Trans-shell contamination (i.e. secondary contamination) is also discussed, but the impact of a prolongation of the shelf ...
