Does the food safety ranking system act as a nudge?

Public health safety is of concern to authorities across the globe and inspector’s food hygiene ranking system has been introduced in many countries. Mandatory disclosure of hygiene ranking information was introduced to empower consumers to make informed decisions regarding foodborne risks. Evaluating available research on public perception and attitude towards such rankings, it seems that the food safety rankings may prompt hygiene compliance by the food business operators and may act as a nudge for consumers to avoid outlets, though with certain caveats. Significant assessment of the scheme remains to be carried out for the ranking system to be an effective nudge for sustainable consumer protection. The public health authorities and organisations need to consider several real-world cognitive and behavioural constraints.
