Kudoa spp.

Kudoa species are a type of microscopic parasitic fungus-like organisms that infect fish, especially after they are caught and stored. They form spores inside the fish’s muscles, which can cause the flesh to become soft, milky, or flaky, affecting the fish's quality. While these parasites usually don't harm humans directly, consuming infected fish may lead to a rare condition called “Kudoa-induced myoliquefaction,” resulting in unpleasant texture changes. Kudoa spp. are of concern mainly to the seafood industry, emphasizing the importance of proper handling and inspection of fish to ensure quality and safety.
