Plastics in the Food Chain: A Scoping Review of Their Environmental, Health, and Food Security Implications

Food Security Challenges and Microplastics: A Comprehensive Review

AI summary · Read the abstract

Researchers examined the intersection of food security and microplastic contamination, finding that microplastics threaten crop yields, soil health, and food chains in ways that could compound existing pressures from population growth and climate change.

Food chain microplastics contamination and impact on human health: a review

AI summary · Read the abstract

This review synthesizes evidence on microplastic transfer through the food chain—spanning seafood, food additives, packaging, and agricultural products—and documents human health impacts including cancer, organ damage, and reproductive impairment. Microplastics are nearly impossible to excrete once absorbed into the circulatory system, making dietary exposure a critical and underappreciated public health concern.

Routes of human exposure to Micro- and Nanoplastics through the food chain: what do literature reviews say?

AI summary · Read the abstract

Researchers conducted an umbrella review of 59 published reviews on microplastics in food chains and found that plastic particles contaminate marine, freshwater, and terrestrial food sources across a vast size range (0.02–16,400 µm), noting that the number of reviews now exceeds primary studies, signaling a need for more standardized research.

Micro- and Nanoplastics Impact on Food Sources of Marine Origin

AI summary · Read the abstract

Researchers reviewed how micro- and nanoplastics contaminate marine-sourced foods including fish, shellfish, and seaweed, raising concerns about human dietary exposure. With billions of metric tons of plastic produced since 1950, ocean food sources represent a significant and growing pathway for plastic particles entering the human body.
