In recent years, an emerging concern in the realm of food safety has been the link between food poisoning and Kudoa septempunctata, a microscopic parasite found in certain fish species. This parasite, originally believed to be harmless, has now been associated with cases of foodborne illness, prompting heightened attention from health authorities and researchers alike [1-2].

Kudoa septempunctata is a myxosporean parasite that primarily infects olive flounder (Paralichthys olivaceus), a popular fish species consumed in East Asia, particularly in countries like Japan and South Korea. Historically, Kudoa septempunctata was thought to cause no harm to humans, as it primarily affected the fish muscle tissues without apparent adverse effects. However, recent investigations have uncovered a potential link between the consumption of contaminated fish and cases of food poisoning [3-4].

The lifecycle of Kudoa septempunctata involves spore release within the fish host's muscle tissues, leading to contamination of the flesh. When infected fish are consumed raw or undercooked, there is a risk of ingesting viable spores, which can subsequently cause infection in humans. This mode of transmission has raised concerns, especially in regions where raw fish dishes, such as sushi and sashimi, are popular [5-6].

Food poisoning associated with Kudoa septempunctata may present with a range of symptoms, including gastrointestinal distress, nausea, vomiting, abdominal pain, and diarrhea. In severe cases, individuals may experience fever and muscle pain. Although the symptoms are generally self-limiting, vulnerable populations, such as the elderly, young children, and immunocompromised individuals, may be at a higher risk of developing complications [7-8].

Health authorities in affected regions are intensifying surveillance efforts to monitor the prevalence of Kudoa septempunctata in fish populations and are implementing regulatory measures to ensure food safety. This includes stricter guidelines for the handling and processing of fish, as well as recommendations for thorough cooking to eliminate potential risks [9-10].


The emerging association between Kudoa septempunctata and food poisoning emphasizes the dynamic nature of food safety challenges. Ongoing research is crucial to further understand the transmission, impact, and potential mitigation strategies associated with this parasite. Consumers are advised to stay informed about the risks and exercise caution when consuming raw or undercooked fish, particularly in regions where Kudoa septempunctata has been identified as a potential food safety concern..
