A comparison of food safety training efficacies.

Country	Training Method	Study Type	Behaviour	Conclusion	Reference
USA	Knowledge and behaviour-based online training video	Seven question quiz from Servy Safe coursebook	Observation by researcher	Behaviour-based training improves handwashing better than knowledge-based training especially during peak hours	[91]
Malaysia	Food safety training course based on regulations and behaviour training	31 questions	Self-reported questionnaire and researcher observations	Behaviour-based training performed better in certain areas than the control group	[112]
USA	Two hours ServSave training	Questionnaire	Self-reported	Volunteers reported a significant increase in food safety knowledge, but behaviour is unchanged. Self-reported data is unreliable	[36]
USA	Customized lessons using ServSafe	Questionnaire	Researcher Observation	Significant improvement in Food safety knowledge	[113]
Korea	Lecture and demonstrations	Questionnaire	Self-reported questionnaire and researcher observations	Increase in knowledge was statistically significant Intervention did not produce a change in behaviour	[64]
USA	Four hours ServSafe class and behaviour training	Questionnaire	Researcher Observation	Hand washing knowledge and behaviour significantly Improved but these did not improve general compliance behaviour	[114]
