MOLECULAR IDENTIFICATION OF Pseudoterranova azarasi LARVAE IN COD (Gadus sp.) SOLD FOR HUMAN CONSUMPTION IN BRAZIL

Abstract

Anisakiasis and Pseudoterranovosis are human diseases caused by the ingestion of live Anisakidae larvae in raw, undercooked or lightly marinated fish. Larvae were collected from one salted cod sold for human consumption in a Sao Paulo market in 2013. One section of one brownish larva was used for molecular analyses. The partial COX2 gene sequence from the larva had a nucleotide identity of 99.8 % with Pseudoterranova azarasi, which belongs to the Pseudoterranova decipiens species complex. The risk of allergy when consuming dead larvae in salted fish is not well known and should be considered.

“…(Kochanowski et al., 2020; Mitsuboshi et al., 2017). Parasites have been detected in fish and fish products (i.e., fish steaks, frozen fish fillets, fish fingers, and cod fillets) (Bao et al., 2019; Hamouda & Younis, 2022; Levsen et al., 2022; Marigo et al., 2015; Ramos, 2020). Foodborne anisakidosis has been associated with the consumption of infected raw fish, such as sushi and sashimi, and the culinary tradition of eating marinated or raw fish in European countries such as Italy (Aibinu et al., 2019).…”
