Summary
Human norovirus (HuNoV) persistence in food involves complex interactions with food components and microbes, not just survival. Understanding these virus-ligand-matrix-microbiota dynamics is key to controlling foodborne illness.
Area of Science:
- Food safety
- Virology
- Microbiology
Background:
- Human norovirus (HuNoV) is a major cause of foodborne illness.
- Current understanding of HuNoV food persistence is often oversimplified.
- Interactions with food matrices and microbiota influence viral behavior.
Purpose of the Study:
- To review molecular mechanisms of HuNoV interactions with food.
- To explore genotype-dependent ligand binding and retention.
- To link molecular interactions to food safety implications.
Main Methods:
- Literature review synthesizing structural, biophysical, and food-model studies.
- Emphasis on interactions with glycans, HBGA-like substances, proteins, and bacterial components.
- Analysis of implications for food matrices like leafy greens and shellfish.
Main Results:
- HuNoV persistence is shaped by genotype-specific interactions with diverse ligands.
- Ligand interactions modulate viral stability, retention, and infectivity in food.
- These interactions explain limitations of conventional detection and control methods.
Conclusions:
- A multi-ligand perspective is crucial for understanding HuNoV foodborne transmission.
- Mechanism-informed strategies are needed for improved detection and risk assessment.
- Integrated understanding of virus-ligand-matrix-microbiota interactions is essential for control.
