Abstract

European legislation stipulates that food no longer intended for human consumption, due to commercial reasons, manufacturing problems, or some defect, can be used in pet feed. However, the presence of former foodstuffs in pet diets could constitute a public health issue because pets can act as reservoirs of antimicrobial resistance genes. In this study, for the first time, biological hazards due to the presence of Escherichia coli and Salmonella in former foodstuff meat products were evaluated. Among the 112 samples of packaged fresh meat (poultry, pork, and beef) collected from cold storage warehouses of a mass market retailer, the overall prevalence of E. coli and Salmonella, the prevalence of strains with multidrug resistance, the phenotypic and genotypic characteristics of strains that produce extended-spectrum β-lactamase, and the presence of biofilm producers were assessed. A high prevalence of E. coli was observed in former foodstuffs of poultry (100%), pork (100%), and beef (93.3%). Salmonella Derby and Salmonella Typhimurium were found in 11.5% of the poultry samples, and Salmonella Typhimurium was found in 13.3% of the pork samples. Salmonella was not recovered from the beef samples. Multidrug resistance was found in E. coli and Salmonella isolates from poultry, pork, and beef. Overall, 18.2% of E. coli isolates and 20% of Salmonella isolates were resistant to various types of antibiotics with various mechanisms of action. Salmonella isolates from pork are an important source of extended-spectrum β-lactamase production. Both E. coli and Salmonella were carriers of antibiotic resistance marker genes ( bla TEM, bla SHV, and bla CTX-M) associated with β-lactamase production in poultry and pork. Approximately 30% of the E. coli isolates from the various types of meat were phenotypically biofilm producers, and all carried the fimH gene. These findings indicate that the use of former foodstuff meat products in pet diets can represent a risk for public health.

  • In Italy, pork and chicken material available for pet food manufacture yielded Salmonella from 12% of samples.

    “A recent study in the Netherlands reported Salmonella isolation from 20% of 35 commercial raw food samples (van Bree et al. 2018), while in Italy, pork and chicken material available for pet food manufacture yielded Salmonella from 12% of samples (Bacci et al. 2019).”
  • In Italy, ESBL producers were prevalent among Salmonella isolates from date-expired human products available for pet food use.

    “while in Italy, ESBL producers were prevalent among Salmonella isolates from date‐expired human products available for pet food use (Bacci et al. 2019).”
  • Multi-resistant E. coli and Salmonella strains were prevalent among poultry and pork material available for pet food manufacture in Italy.

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.
