Growing global concern surrounds microplastics, found in various environments. However, data on microplastics contamination in salted shrimp and associated health risks remain scarce. We analyzed whether salted shrimps sold in markets in a main city in Amazonas state (Brazil), are contaminated with microplastics. We examined 150 specimens of Macrobrachium amazonicum and found 396 potential microplastics in 129 individuals (86%). The number of particles per gram of body mass was highest in the gastrointestinal tract, with 60% of them ranging in size from 1,000 to 5,000 µm, predominantly dark blue fibers (80%). The contamination likely originates from the environment and the salt used during processing in the region where the shrimps are captured. Our findings point to a potential health risk to the many consumers of salted shrimp in the Amazon region.
