Microplastics in Food Environment: Sources, Consequences and Control Strategies
Summary
This review examines how microplastics enter the food supply — through contaminated feed, raw ingredients, and food processing — and can move up the food chain through a process called trophic transfer, concentrating pollutants as they go. The authors argue that monitoring and removal strategies are urgently needed across the entire food supply chain to protect both food security and human health.
Increasing accumulation of microplastics in the environment and food are of significant concern. It is unavoidable for people to consume tainted food that contains MPs, which is dangerous for both food security and people’s health. This situation creates the need to focus on monitoring and eradicating MPs across the food supply chain. MPs can move across the food chain by trophic transfer, thus leading to bioaccumulation of contaminants. MPs occur in feed, raw food and in processed foods. MPs exist in various types, size and shape which affects their absorption and degree of hazard. This review highlights the existence of MPs in food and explain its implications to food security and potential risks to human health.
