ClearExposure of black soldier fly larvae to microplastics of various sizes and shapes: Ingestion and egestion dynamics and kinetics
Researchers studied how black soldier fly larvae, used to convert food waste into animal feed, interact with microplastics of different sizes and shapes. The larvae ingested microplastics along with their food but could not fully break them down, passing most of them through in their waste. This raises food safety concerns because if microplastics persist in the larvae, they could transfer up the food chain when the larvae are used as feed for livestock or fish.
Micro- and nanoplastic size affects uptake and digestive tract region residence time in black soldier fly larvae during food waste bioconversion
Researchers studied how black soldier fly larvae, increasingly used to recycle food waste, handle micro- and nanoplastics of different sizes during digestion. They found that nanoplastics remained in the gut significantly longer than larger microplastics and were retained even after the larvae stopped eating contaminated food. The findings raise concerns that nanoplastics could enter the food chain when larvae-derived products are used as animal feed or fertilizer.
Quantifying ingested debris in marine megafauna: a review and recommendations for standardization
This review examined published methods for quantifying ingested plastic debris in marine megafauna — including whales, turtles, and sharks — and found wide variation in reporting practices. The authors propose standardized protocols for sample collection, processing, and data reporting to enable meaningful comparisons across species and regions.
Disease Risk Analysis in sea turtles: A baseline study to inform conservation efforts
This study compiled the first comprehensive disease risk analysis for all seven sea turtle species, listing major health threats including plastic ingestion and entanglement. Sea turtles are sentinel species for ocean health, and their exposure to plastic pollution signals broader ecosystem contamination.
