  • clonal emergence of extended spectrum β lactamase ctx m 2 producing salmonella enterica serovar virchow isolates with reduced susceptibilities to ciprofloxacin among Poultry and humans in belgium and france 2000 to 2003
    Journal of Clinical Microbiology, 2006

    Abstract:

    Antibiotic treatment is not required in cases of Salmonella enterica gastroenteritis but is essential in cases of enteric fever or invasive salmonellosis or in immunocompromised patients. Although fluoroquinolones and extended-spectrum cephalosporins are the drugs of choice to treat invasive Salmonella, resistance to these antibiotics is increasing worldwide. During the period 2000 to 2003, 90 Salmonella enterica serovar Virchow Poultry and Poultry Product isolates and 11 serovar Virchow human isolates were found to produce an extended-spectrum beta-lactamase, CTX-M-2, concomitantly with a TEM-1 beta-lactamase. The bla(CTX-M-2) gene was located on a large conjugative plasmid (>100 kb). Pulsed-field gel electrophoresis indicated a clonal relationship between the Poultry and human isolates. All these isolates displayed additional resistance to trimethoprim-sulfamethoxazole and tetracycline as well as a reduced susceptibility to ciprofloxacin (MICs of between 0.5 and 1 mu g/ml). CTX-M-2-producing Salmonella with a reduced susceptibility to fluoroquinolones constitutes a major concern, since such strains could disseminate on a large scale and jeopardize classical antibiotic therapy in immunocompromised patients.

  • emergence of extended spectrum β lactamase ctx m 9 producing multiresistant strains of salmonella enterica serotype virchow in Poultry and humans in france
    Journal of Clinical Microbiology, 2004
    Co-Authors: Francoisxavier Weill, Renaud Lailler, Karine Praud, Annaelle Kerouanton, Laetitia Fabre, Anne Brisabois, Patrick A D Grimont, Axel Cloeckaert
    Abstract:

    During 2002 to 2003, eight Salmonella enterica serotype Virchow Poultry and Poultry Product isolates from various sources (chicken farms, Poultry slaughterhouse, or retail store) and one S. enterica rough strain isolated from human feces were found to produce extended-spectrum β-lactamase CTX-M-9. Poultry and Poultry Product isolates were recovered from different locations in the southwest of France. The human rough isolate had sequences of flagellin genes (fliC and fljB) typical of serotype Virchow and ribotyping and pulsed-field gel electrophoresis (PFGE) patterns closely similar to those of serotype Virchow strains. PFGE confirmed the clonal relationship between the Poultry isolates, while the human isolate displayed a pattern with 94% homology. The blaCTX-M-9 gene was located on a conjugative plasmid and was shown to be linked to orf513. Plasmid profiling found a very similar EcoRI restriction pattern in six transconjugants studied, including transconjugants obtained from the human isolate. A single hatchery, supplying chicks to the six farms, was identified. Emergence of extended-spectrum β-lactamase-producing S. enterica strains in food animals is a major concern, as such strains could disseminate on a large scale and lead to antibiotic therapy difficulties.

  • twenty two years of u s meat and Poultry Product recalls implications for food safety and food waste
    Journal of Food Protection, 2017
    Co-Authors: Acton Gorton, Matthew J Stasiewicz
    Abstract:

    ABSTRACT The U.S. Department of Agriculture, Food Safety and Inspection Service maintains a recall case archive of meat and Poultry Product recalls from 1994 to the present. In this study, we collected all recall records from 1994 to 2015 and extracted the recall date, meat or Poultry species implicated, reason for recall, recall class, and pounds of Product recalled and recovered. Of a total of 1,515 records analyzed, the top three reasons for recall were contamination with Listeria, undeclared allergens, and Shiga toxin–producing Escherichia coli. Class I recalls (due to a hazard with a reasonable probability of causing adverse health consequences or death) represented 71% (1,075 of 1,515) of the total recalls. The amounts of Product recalled and recovered per event were approximately lognormally distributed. The mean amount of Product recalled and recovered was 6,800 and 1,000 lb (3,087 and 454 kg), respectively (standard deviation, 1.23 and 1.56 log lb, respectively). The total amount of Product recal...
