A critical review of microplastic pollution in breeding industry：sources, distribution, impacts, and characterization techniques, mitigation strategies and future research directions.

Microplastic (MP) pollution has garnered significant attention due to its detrimental effects on ecosystems and human health. If MPs contaminate farmed animals, they are more likely to enter the human body through the food chain, thereby impacting human health. Exploring MPs in breeding industry can provide a theoretical basis for breeding industry to prevent MP pollution. However, there is currently a lack of comprehensive summaries and overviews of MPs research in the industry as a whole. The core focus of the review is to improve our understanding of MPs in the breeding industry and provide valuable references and support for the development of mitigation strategies and policies. The review found that there are more studies related to MP pollution in the breeding industry, but there is inadequate information on the prevention and control technology. This review proposes strategies for prevention and control and discusses future research directions.
