Food handler food safety practices differ significantly between self-assessment and direct observation. Knowledge positively impacts both, but attitudes moderate these effects differently, highlighting the need for distinct evaluation methods.
Area of Science:
- Food Safety
- Behavioral Science
- Public Health
Background:
- Food safety knowledge, attitudes, and practices (KAP) studies are common but yield controversial results regarding practices.
- Self-assessment and observation are primary methods for evaluating food handler practices, often used interchangeably despite potential differences.
Purpose of the Study:
- To differentiate between observed and self-reported food safety practices.
- To verify the effect of variables on food safety indicators using structural equation modeling.
- To examine the relationship between cognitive factors and food safety practices.
Main Methods:
- A questionnaire assessed food safety knowledge, attitudes, self-reported practices, and risk perceptions in 183 food handlers.
- Observed practices were evaluated using a checklist during a typical workday.
- Two structural equation models were developed based on self-reported and observed data.
Main Results:
- Self-reported practices showed a positive effect of knowledge and a negative effect of risk perception; attitudes moderated the knowledge-practice link.
- Observed practices demonstrated a positive effect of knowledge, with attitudes strengthening this relationship but not directly impacting practices.
- Risk perception negatively influenced self-reported practices, while attitudes did not directly affect observed practices.
Conclusions:
- Self-reported and observed food safety practices are distinct metrics.
- Evaluation methods for food handler practices require careful consideration and proper interpretation.
- Understanding the interplay of knowledge, attitudes, and risk perception is crucial for improving food safety behaviors.
