“…The present study showed a considerably higher prevalence of Salmonella in carcass samples (16.10%) than feces (3.38%), which is consistent with the findings from previous reports of Teklu and Negussie (2011) ), Dabassa and Bacha (2012) on sheep and cattle samples, respectively. However, our results contrast with the study's finding of Dong et al (2014), which indicated higher Salmonella prevalence in feces than in carcasses. The relationship between fecal shedding and carcass contamination seems weak.…”

The aims of our work are to estimate the prevalence of Salmonella isolated from carcasses and feces of cattle and sheep in the two biggest slaughterhouses in Algiers, Algeria, and to characterize the obtained strains by serotyping and antimicrobial resistance testing. The detection of Salmonella was performed by the conventional culture method and isolates were confirmed by PCR. Susceptibility to antibiotics was carried out by agar disc diffusion method. The results showed that 10.17% of samples were Salmonella positive. Carcass samples were more contaminated than fecal samples. Serotyping of the 84 Salmonella isolates has enabled to identify 10 different serovars; the most predominant was S. Muenster. The invA gene was detected in 96.43% of isolates whereas all S. Typhimurium strains were positive for spy gene. Sixty-eight (80.95%) isolates were resistant to at least one of the 28 antibiotics tested and exhibited 17 different antimicrobial resistance patterns. The most frequently observed resistance was to streptomycin (69.05%). While 22.62 % of the isolates were MDR, two S. Typhimurium showed an‘‘ACSSuT’’ pentaresistance pattern. Considering the importance of this group of bacteria for public health, Salmonella control is necessary at several steps of food production to ensure safe products for consumers.

“…However, because of the small number of isolates, further research should be done to confirm the current findings. This possible absence of the pathogen may also explain why E. coli O157:H7 was rarely detected in the downstream carcasses even though showers and other pre-slaughter intervention methods are rare in the four investigated plants (Dong et al, 2014). The low prevalence of E. coli O157:H7 on the pre-slaughter cattle in lairage also indicates a low rate of cross-contamination through animaleanimal and/or animal-environment-animal contact during transport or a low prevalence among the cattle in the feedlot.…”

“…The frequency and dosage of the antimicrobial agents used in cattlefeeding facilities in China might explain this unique phenomenon. However, because of the preliminary small number of samples and the lack of the information about the slaughtered cattle (such as their source, nutrition, breed and treatment history) (Dong et al, 2014), further studies involving larger sample sizes and more traceable data are necessary to verify the current findings.

The aims of this study were to determine the prevalence of Salmonella enterica (S. enterica) antimicrobial resistance based upon phenotypic assessment, and level of sanitation indicator organisms from 150 beef carcasses collected from three representative abattoirs in eastern, central, and southern Ethiopia. Samples were screened for S. enterica prevalence following the U.S. Department of Agriculture Microbiology Laboratory Guidebook (MLG) and confirmed by real‐time PCR. The S. enterica isolates were phenotypically evaluated for susceptibility to a panel of 13 antimicrobials using disk diffusion method as described in Clinical and Laboratory Standard Institutes guidelines. In addition, the coliform, total coliform, and generic E. coli populations were quantified by plating onto E. coli/coliform petrifilms. A total of 45 isolates of S. enterica were confirmed using real‐time PCR. The overall prevalence of S. enterica at the carcass level was 22.7% (95% CI, 16.0–30.0). However, based on the sampling points, S. enterica prevalence detected on hides was 13.3% (95% CI, 8.0–18.7), pre‐evisceration was 12.0% (95% CI, 7.3–17.3), and post‐evisceration was 4.7% (95% CI, 1.3–8.0). The prevalence of S. enterica was significantly lower on post‐evisceration as compared to hides (p = .009) and pre‐evisceration (p = .022). No differences were detected for the prevalence of S. enterica between abattoirs (p = .346). Finally, the prevalence of S. enterica was highest during the wet season (p = .011). The overall mean log CFU/cm2 ± SD of generic E. coli, coliform, and total coliform counts were 4.55 ± 0.99, 4.91 ± 1.13, and 4.98 ± 1.09, respectively. About 20% of S. enterica exhibited phenotypic multidrug resistant. The most frequently detected resistance was to Tetracycline (28.9%), followed by Streptomycin (22.2%) and Sulfisoxazole (20.0%). The data from this study highlight the need to implement interventions on improvement of sanitary practices in abattoirs.
