Quantifying microbial recontamination in food production is crucial for food safety. This study reviews predictive models for assessing recontamination risks from factory environments, aiding quantitative microbial risk assessment (MRA).

Area of Science:

  • Food Safety
  • Microbial Risk Assessment
  • Predictive Modeling

Background:

  • Foodborne illnesses often stem from product recontamination within food factories.
  • Accurate quantification of recontamination is essential for robust quantitative microbial risk assessment (MRA).

Purpose of the Study:

  • To review existing modeling approaches for quantifying food product recontamination from the factory environment.
  • To identify suitable models for assessing recontamination routes including air, equipment, and hand contact.
  • To propose a systematic approach for modeling contamination from surfaces into food products.

Main Methods:

  • Literature review of predictive modeling approaches for microbial recontamination.
  • Analysis of recontamination routes: airborne, equipment-mediated, and hand-to-product transfer.

  • Development of a general systematic approach for contamination modeling.

    • Main Results:

    • Few existing models are directly applicable to the food industry; many originate from aquatic or environmental systems.
    • Identified key recontamination pathways within food processing environments.
    • Provided parameter ranges for a proposed systematic contamination modeling approach.

    Conclusions:

    • Predictive models are necessary to quantify recontamination in food MRA.
    • A systematic approach is proposed to model contamination from various sources (air, hands, surfaces) into food products.
    • Further adaptation of existing models or development of new ones is needed for the food industry.
