Anisakis is a marine parasite that is increasingly present in the food health conversation. It can be found in fish and cephalopods that we frequently consume and, in some cases, can cause everything from digestive discomfort to severe allergic reactions.
As Dr. Lourdes Pérez González, of the Hospital Universitario Quirónsalud Madrid, points out, it is the larval form that represents a risk to humans, as it lodges in fish such as hake, anchovies, mackerel or squid, among others. Recent studies warn that some species have a parasitization rate of more than 90%.
What symptoms can it cause?
Consumption of fish with anisakis may trigger:
- Digestive problems (abdominal pain, vomiting, appendicitis-like symptoms).
- Allergic reactions (urticaria, angioedema, even anaphylaxis).
- Mixed tables combining both reactions.
Diagnosis and treatment
Diagnosis is based on a clinical history and can be confirmed by allergy testing or, in more severe cases, by endoscopy. Anisakis-specific IgE (immunoglobulin E) levels may also be a clue after a reaction.
How to prevent its presence in fish?
Effective measures are available to minimize the risk of infection:
At Tedepad, we believe that prevention starts long before the fish reaches your table. That’s why we develop technological solutions that act from the source, such as our system to treat viscera on board and reduce the proliferation of anisakis at sea.
