The prevalence of allergic diseases such as asthma, diarrhea and vomiting in the consumer population related to the high prevalence of parasites in fish Anisakidos captured a public health alert.
In a work of Dr. H. Bracho-Espinoza, the number of cases of respiratory diseases (allergic asthma), and gastric (diarrhea and vomiting), mainly in children, it was considered very high showing that remains of parasites anisakidae family or chemicals secreted by them, specifically the Contracaecum spp and spp pseudoterranova genres are associated with immediate hypersensitivity reactions to anisakis antigens mediated by IgE antibodies as a response to allergens parasite. According Bracho-Espinoza in the fishing area referred persist predisposing factors (own evolutionary cycle of the parasite) that do maintain and increase the prevalence of parasites Anisakidos in fish caught through craft fishing methods shore, keeping an imminent risk health of fishermen and consumers in general.
Adult parasites in digestive cavity of fish
I keep saying Bracho-Espinoza, who failing health guidelines to ensure the product safe fishing to the consumer, such population as lack of freezing and evisceration of caught fish, internal migration of the parasite occurs from the digestive cavity mesentery and muscle, even reach the hemal canal, going so that when cutting the fish will always be remnants of the parasite. He also reported that the species of fish where the prevalence and degree of parasitism per specimen was higher, as in the Colombian Caribbean, is in fish from the Mugilidae family, as smooth Mugil, Mugil curema , Mugil insilis and Eugerres sp ; which by being lower economic value, they are mainly for household consumption. Finally he said Bracho-Espinoza, ignorance was detected by fishermen and consumers about this parasitism and its consequences, aggravated by lack of permitology and health inspection by the competent health authorities, also by the food habit of eating raw fish salted marinated in vinegar or cooked in acid; culinary mechanisms that do not guarantee the complete elimination of the parasite or their remains.
