Effective and sustainable interventions are necessary for long-term improvement of
food safety. This review provides a summary of food safety interventions evaluated
in selected low- and middle-income countries in Asia between 2000 and 2020. A
systematic screening of published articles from PubMed and CabDirect databases
was carried out with the aid of Rayyan QCRI software. A total of 25 studies were
considered in the review. A ‘before and after’ study design was the most frequently
used design (64%), while five studies (20%) used a randomized control trial (RCT) design. Interventions applied focused on training to improve knowledge, attitudes, and
practices (KAP) towards safe food (60%) or on specific technologies (40%). Nine of the
25 studies were specific on the value chain considered: cattle (1), poultry (1), pigs (4)
and fish value chains (3). Except for one study, all interventions reported some level
of success; 17 were rated as having a high level of success, defined differently across
studies. However, there is a clear evidence gap for the efficacy and cost-effectiveness
of food safety interventions in market settings, both consumer- and vendor-facing. A
rigorous and standardized assessment of intervention effectiveness and sustainability
is recommended, to not only identify areas of improvement, but also to ensure scaling
of interventions with demonstrated evidence of success and sustainability. |
