Vancomycin-resistant enterococci (VRE) are a growing concern. This study found low VRE environmental prevalence in shellfish and water, but frequent contamination in raw chickens.

Area of Science:

  • Environmental microbiology
  • Food safety
  • Public health

Background:

  • Vancomycin-resistant enterococci (VRE) pose a significant threat, particularly in hospital settings.
  • Limited evidence exists on the role of food and environmental pathways in VRE transmission.
  • Biomonitoring using shellfish can assess environmental VRE presence.

Purpose of the Study:

  • To investigate the occurrence of VRE in environmental samples, including shellfish, water, and raw chickens.
  • To evaluate the effectiveness of different agar media for VRE detection.
  • To assess the potential for food and environmental spread of VRE.

Main Methods:

  • Shellfish, water, and raw chicken samples were collected for VRE analysis.
  • Pre-enrichment techniques were employed for sample preparation.

  • Selective agars, including Lewisham and Slanetz and Bartley agars, were used for VRE isolation and identification.

    • Main Results:

    • VRE were detected in 1.6% of shellfish samples using Lewisham and Slanetz and Bartley agars.
    • Subsequent analysis found VRE in 2.7% of shellfish and 18.5% of raw chicken samples.
    • No VRE were detected in unchlorinated water samples.

    Conclusions:

    • Environmental prevalence of VRE appears to be low in the studied aquatic environments.
    • Raw chickens represent a significant source of VRE contamination.
    • Further research is needed to fully understand VRE transmission routes.
