What is Kudoa septempunctata?

A photo of Kudoa septempunctataKudoa septempunctata is a species of parasite (mucous sporozoite) of the genus Kudoa that parasitizes Bastard Hailbit (Hirame). It is approximately 10 µm in size and has a “hemispherical” shape when parasitized on fish.

Most cases of food poisoning due to cudweed are associated with fresh flatfish for raw consumption (e.g., flatfish sashimi). The infection rate and amount of infection are particularly high in farmed flatfish, which accounts for 60% of the food ingredients that cause kudoa food poisoning.

It is characterized by transient vomiting and diarrhea within a few hours after eating, with symptoms ending in a mild illness. Kudua has been shown to lose its virulence by freezing at -20°C for 4 hours or more, or by heating to a core temperature of 75°C for 5 minutes or more.

Therefore, food poisoning can be prevented by freezing it once and then eating or cooking it.
