Now With 283 Times More Parasites

Fish are infected with 283 times more parasitic worms than they were 40 years ago. Anisakis worms can infect a variety of marine fish and squid, as well as marine mammals such as whales and dolphins – and can be present in fish used raw for sushi.

Chelsea Wood at the University of Washington in Seattle and her colleagues analyzed the abundance of Anisakis, or herring worm, between 1978 and 2015. The team gathered data on the average number of parasites per fish from 123 studies – which included 56,778 fish across 215 species – and found a 283-fold increase over nearly 40 years.
