Slaughterhouse and wet market wastes are pollutants that have been always neglected by society. According to the Food and Agriculture Organization of the United Nations, more than three billion and nineteen million livestock were consumed worldwide in 2018, which reflects the vast amount and the broad spectrum of the biowastes generated. Slaughterhouse biowastes are a significant volume of biohazards that poses a high risk of contamination to the environment, an outbreak of diseases, and insecure food safety. This work comprehensively reviewed existing biowaste disposal practices and revealed the limitations of technological advancements to eradicate the threat of possible harmful infectious agents from these wastes. Policies, including strict supervision and uniform minimum hygienic regulations at all raw food processing factories, should therefore be tightened to ensure the protection of the food supply. The vast quantity of biowastes also offers a zero-waste potential for a circular economy, but the incorporation of biowaste recycling, including composting, anaerobic digestion, and thermal treatment, nevertheless remains challenging.
屠宰场和湿市场废物是一直被社会忽视的污染物。根据联合国粮食及农业组织的数据，2018 年全球消费了超过 31.9 亿头牲畜，这反映了生物废物产生的巨大数量和广泛范围。屠宰场生物废物是一种大量的生物危害物，对环境、疾病爆发和不安全的食品安全构成了高风险。这项工作全面回顾了现有的生物废物处理实践，并揭示了技术进步消除这些废物中可能有害的传染性病原体威胁的局限性。政策，包括对所有生食品加工厂的严格监督和统一的最低卫生法规，应予以加强，以确保食品供应的安全。大量的生物废物也为循环经济提供了零浪费的潜力，但包括堆肥、厌氧消化和热处理在内的生物废物回收的实施仍然具有挑战性。
