Human anisakiasis, a food-borne disease from Anisakis worms, is underestimated globally. It can lead to chronic illness and allergic reactions upon re-exposure to Anisakis allergens.
Area of Science:
- Parasitology
- Foodborne Diseases
- Immunology
Background:
- Human anisakiasis is caused by Anisakis spp. nematodes.
- Symptoms mimic bacterial or viral gastroenteritis.
- Global seafood trade increases transmission risk.
Purpose of the Study:
- Review aspects of human anisakiasis.
- Explain its link to chronic and allergic conditions.
Main Methods:
- Literature review of anisakiasis.
- Analysis of disease manifestation and immune response.
Main Results:
- Anisakiasis risk is underestimated in developed nations.
- Initial infection can become chronic.
- Sensitization to Anisakis allergens causes allergic exacerbation upon secondary exposure.
Conclusions:
- Anisakiasis is a significant food-borne disease.
- It poses risks beyond initial infection, including chronic and allergic conditions.
