Summary
Kudoa septempunctata, a parasite in olive flounder, causes food poisoning with vomiting and diarrhea. Increased cases in Japan highlight the need for clinical awareness of this emerging pathogen.
Area of Science:
- Foodborne illnesses
- Parasitology
- Clinical microbiology
Background:
- Kudoa septempunctata is an emerging parasite responsible for food poisoning.
- Olive flounder (Paralichthys olivaceus) is a common source of infection.
Observation:
- Three cases of food poisoning were reported following consumption of raw olive flounder.
- Out of 358 individuals exposed, 94 developed gastrointestinal symptoms within 1-9 hours.
- Symptoms included vomiting and diarrhea, typically resolving within 2 days.
Findings:
- Kudoa septempunctata infection presents as acute gastroenteritis.
- The parasite is linked to raw aquacultured olive flounder consumption.
- Most cases are self-limiting, with rare hospitalization for dehydration.
Implications:
- Clinicians should consider Kudoa septempunctata in diagnosing food poisoning, especially with a history of consuming raw olive flounder.
- Increased incidence in Japan necessitates greater awareness and diagnostic preparedness.
- Public health initiatives may be required to address the rising trend of olive flounder-associated food poisoning.

01:18Bacterial Gastroenteritis
Bacterial gastroenteritis, characterized by diarrhea, abdominal cramps, and vomiting, is often caused by ingestion of contaminated food or water and is frequently associated with pathogenic Escherichia coli strains. These microbes exploit two principal mechanisms to inflict disease.Shiga toxin–producing E. coli, also referred to as STEC—notably O157:H7—release Shiga toxins that target ribosomes, blocking protein synthesis. The B subunit of the toxin binds the host glycolipid receptor...
01:30Reservoir of Infection
Infectious diseases arise from intricate interactions between pathogens and their reservoirs. A reservoir of infection refers to the natural habitat where a pathogen lives, grows, and multiplies, serving as a continual source of infection. Reservoirs are broadly classified as either living or nonliving, and each plays a unique role in disease transmission, significantly influencing public health interventions and control strategies.Humans act as reservoirs for a wide array of pathogens,...
01:23Investigation of Disease Outbreaks
Multistate foodborne outbreaks pose significant public health risks and require meticulous investigation to identify sources and implement control measures. The Centers for Disease Control and Prevention (CDC) utilizes a dynamic seven-step process for these investigations, integrating data from laboratories, interviews, and environmental assessments to protect public health.Outbreak Detection: The detection of multistate outbreaks typically begins with PulseNet, the CDC's national laboratory...
01:14Conditioned Taste Aversion
Conditioned taste aversion, also known as sauce béarnaise syndrome, is a phenomenon in which an individual develops an aversion to a certain food taste following a negative experience, typically illness. This form of aversion is a type of classical conditioning in which the taste of the food (conditioned stimulus, CS) is associated with the experience of illness (unconditioned stimulus, UCS).
A notable characteristic of conditioned taste aversion is that it often requires only a single exposure...

01:25Cholera
Cholera is an acute gastrointestinal disease caused by the Gram-negative bacterium Vibrio cholerae. It is transmitted primarily via the fecal-oral route through the ingestion of contaminated water or food.Vibrio cholerae is a motile, Gram-negative bacterium of the family Vibrionaceae, primarily associated with waterborne outbreaks in areas with inadequate sanitation. Although over 200 serogroups of V. cholerae exist, only O1 and O139 are responsible for epidemic cholera. The O1 serogroup,...
01:23Microbial Spoilage of Food
Microbial food spoilage refers to the degradation of food quality resulting from the metabolic activity of microorganisms such as bacteria, yeasts, and molds. These microbes proliferate on various food substrates depending on factors such as moisture content, nutrient availability, and storage conditions, leading to undesirable sensory and structural changes.Bacteria are primary agents of spoilage in high-moisture, nutrient-dense foods like meat, milk, and vegetables. Microbial spoilage occurs...
