Abstract

Objective—To investigate Salmonella enterica infections at a Greyhound breeding facility. Design—Cross-sectional study. Animal and Sample Populations—138 adult and juvenile dogs and S enterica isolates recovered from the dogs and their environment. Procedures—The investigation was conducted at the request of a Greyhound breeder. Observations regarding the environment and population of dogs were recorded. Fecal, food, and environmental specimens were collected and submitted for Salmonellaculture. Isolates were serotyped and tested for susceptibility to 16 antimicrobials. Isolates underwent genetic analyses by use of pulsed-field gel electrophoresis and ribotyping. Results—S enterica was recovered from 88 of 133 (66%) samples of all types and from 57 of 61 (93%) fecal samples. Eighty-three (94.3%) of the isolates were serotype Newport, 77 (87.5%) of which had identical resistance phenotypes. Genetic evaluations suggested that several strains of S enterica existed at the facility, but there was a high degree of relatedness among many of the Newport isolates. Multiple strains of Salmonella enterica serotype Newport were recovered from raw meat fed on 1 day. Conclusions and Clinical Relevance—S enterica infections and environmental contamination were common at this facility. A portion of the Salmonellastrains detected on the premises was likely introduced via raw meat that was the primary dietary constituent. Some strains appeared to be widely disseminated in the population. Feeding meat that had not been cooked properly, particularly meat classified as unfit for human consumption, likely contributed to the infections in these dogs.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Salmonella contamination of surfaces was prevalent in a raw-feeding kennel establishment despite good daily cleaning routines.

    “Trials of domestic cleaning and disinfection routines have shown them to be ineffective at eliminating Salmonella contamination from bowls (Weese & Rousseau 2006), while Salmonella contamination of surfaces was prevalent in a raw‐feeding kennel establishment despite good daily cleaning routines (Morley et al. 2006).”
  • Salmonella serovars shed by raw-fed dogs correlate with those isolated from their pet food.

    “Salmonella serovars shed by raw‐fed dogs correlate with those isolated from their pet food (Mayer et al. 1976, Joffe & Schlesinger 2002, Morley et al. 2006, Finley et al. 2007), and these food isolates, as already discussed, include serovars associated with human disease.”
  • Clinical salmonellosis has been reported in association with raw feeding.

    “Diarrhoea does not appear to be a typical feature of Salmonella‐shedding dogs (Brisdon et al. 2006, Finley et al. 2007, Reimschuessel et al. 2017), although clinical salmonellosis has been reported in association with raw feeding (Morley et al. 2006).”
  • Food isolates from raw-fed dogs include serovars associated with human disease.

    “Salmonella serovars shed by raw‐fed dogs correlate with those isolated from their pet food (Mayer et al. 1976, Joffe & Schlesinger 2002, Morley et al. 2006, Finley et al. 2007), and these food isolates, as already discussed, include serovars associated with human disease.”
  • Greyhounds fed on raw meat were found to commonly shed multi-resistant strains of Salmonella.

    “Greyhounds fed on raw meat were also found to commonly shed multi‐resistant strains of Salmonella (Morley et al. 2006)”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
