    Summary
    This summary is machine-generated.

    Subcutaneous bacteria in turkey carcasses are minimal, especially in flesh and skin-flesh interfaces. Current methods primarily detect surface bacteria, not deep tissue contamination.

    Area of Science:

    • Food Microbiology
    • Poultry Science
    • Microbial Quantification

    Background:

    • Accurate quantification of bacterial contamination on poultry carcasses is crucial for food safety.
    • Understanding bacterial distribution (surface vs. subcutaneous) informs processing and handling protocols.
    • Previous methods may not differentiate between surface and deeper microbial populations.

    Purpose of the Study:

    • To quantify subcutaneous bacteria in turkey carcasses using two distinct methods.
    • To compare bacterial loads in skin, skin-flesh interface, and flesh.
    • To assess the influence of surface disinfection on subcutaneous bacterial counts.

    Main Methods:

    • Employed two quantitative methods to assess bacterial populations.
    • Analyzed samples from fresh, refrigerated, and frozen turkey carcasses.

  • Included analysis of skin surface, skin layer, skin-flesh interface, and flesh.

    • Main Results:

    • Subcutaneous bacteria were detected in low numbers in the skin-flesh interface and flesh.
    • A significant proportion (49%) of skin-flesh interface and flesh samples showed no detectable bacteria.
    • Chemically disinfecting the skin surface reduced detected bacterial numbers in skin samples.

    Conclusions:

    • The skin blending method primarily quantifies skin surface and layer flora, not subcutaneous bacteria.
    • Subcutaneous bacterial populations in turkey carcasses are generally not significant enough to impact overall microbial quantification results.
    • Current quantification methods for poultry carcass bacteria focus on surface contamination.
