Economic impacts and mitigation strategies of African Swine Fever in China: a systematic review

BACKGROUND: African Swine Fever (ASF) and food safety issues present significant challenges to the global food industry. The Food and Agriculture Organization (FAO) notes that food safety issues can result in economic losses in the food industry. The impact of ASF has been particularly harsh, affecting over half of China's provinces. However, few study has examined its specific economic impact on China. This study aims to explore ASF's economic impacts from 2018 to 2022 and analyze existing mitigation strategies in China. METHODS: This study used a systematic review methodology to synthesize journal articles published in English between 2018 and 2022 from four databases (Pubmed, Web of Science, Scopus, Embase). Journals are included in the study if they discuss the economic impact of ASF in China or provide strategies for mitigation. RESULTS: Our search yielded 49 results, with 11 papers included in the final review. On average, ASF causes about 108 billion losses in 2018, and this figure is increasing to 127 billion in 2019. Current interventions are divided into three types: reforming food manufacturing companies (n = 5), promoting advanced agricultural techniques like vertical farming (n = 4), and adopting a new food supervision system (n = 2). Although these strategies have provided relief, the effectiveness of these strategies remain to be investigated in the future. CONCLUSIONS: ASF's economic loss is substantial and increasing. The study concludes three main strategies for addressing food safety concerns: reforming food manufacturing companies, promoting advanced agricultural techniques like vertical farming, and adopting a new food supervision system. However, future studies should focus on the effectiveness analysis regarding these strategies. KEY MESSAGES: • This study highlights the need for a comprehensive approach to address global food safety issues. • Implementing the proposed strategies can promote a healthier and more sustainable food system.
