Intricate links between aquatic animals and their environment expose them to chemical and pathogenic hazards, which can disrupt seafood supply. Here we outline a risk schema for assessing potential impacts of chemical and microbial hazards on discrete subsectors of aquaculture—and control measures that may protect supply. As national governments develop strategies to achieve volumetric expansion in seafood production from aquaculture to meet increasing demand, we propose an urgent need for simultaneous focus on controlling those hazards that limit its production, harvesting, processing, trade and safe consumption. Policies aligning national and international water quality control measures for minimizing interaction with, and impact of, hazards on seafood supply will be critical as consumers increasingly rely on the aquaculture sector to supply safe, nutritious and healthy diets.

水生动物与其环境之间错综复杂的联系使它们面临化学和病原体危害，这可能会扰乱海鲜供应。在这里，我们概述了用于评估化学和微生物危害对水产养殖各个分部门的潜在影响的风险模式，以及可以保护供应的控制措施。随着各国政府制定战略，实现水产养殖海产品产量的扩大，以满足不断增长的需求，我们建议迫切需要同时关注控制那些限制其生产、收获、加工、贸易和安全消费的危害。随着消费者越来越依赖水产养殖部门提供安全、营养和健康的饮食，协调国家和国际水质控制措施的政策至关重要，以最大限度地减少海产品供应中危害的相互作用和影响。
