Antibiotic use in aquaculture, policies and regulation, health and environmental risks: a review of the top 15 major producers

Abstract This review focuses on the current status of antibiotics use, effects on animal health and the environment, existing policies and regulatory mechanisms in the top 15 producing countries. Fifty papers were reviewed and represented the bulk of literature worldwide. We observed that 67 antibiotic compounds were used in 11 of the 15 countries between 2008 and 2018. Among these countries, 73% applied oxytetracycline, sulphadiazine and florfenicol. On average, countries used 15 antibiotics and the top users included Vietnam (39), China (33) and Bangladesh (21). On environmental and health risks, the review revealed sufficient evidence that directly links antibiotics use to food safety, occupational health hazards and antimicrobial resistance. Environmental risks included residue accumulation, aquatic biodiversity toxicity, microbial community selection…
