Summary
Salmonella bacteria can survive in various environments, impacting public health. Understanding their environmental persistence and inactivation kinetics is crucial for controlling their spread.
Area of Science:
- Microbiology
- Environmental Science
- Food Safety
Context:
- Salmonella poses a significant epidemiological threat due to its environmental survival.
- Factors influencing bacterial survival in diverse environments (surfaces, liquids, soil) are critical.
- Understanding inactivation kinetics, such as Decimal Reduction Time (D-value) or T90-rates, is essential for microbial control.
Purpose:
- To review and consolidate data on the environmental persistence of Salmonella species.
- To highlight the epidemiological significance of Salmonella's environmental survival.
- To identify key factors affecting bacterial survival and inactivation.
Summary:
- This review compiles literature data on the tenacity of Salmonella enteritidis and Salmonella typhimurium in various environmental matrices.
- It covers survival on surfaces, in animal housing (stables), slurry, pastures, soil, water, wastewater, and within living vectors.
- The study also touches upon mathematical models for thermal inactivation kinetics (DT values/T90-rates).
Impact:
- Provides a foundational understanding of Salmonella environmental persistence for risk assessment.
- Informs strategies for controlling Salmonella contamination in agricultural and food production settings.
- Highlights the need for further research into environmental factors affecting Salmonella survival and inactivation.
