Anisakis pegreffii and A. simplex sensu stricto (s.s.) are the main etiological agents causing human anisakiasis. Here, we aimed to investigate based on the pepsin digestion method of the occurrence of Anisakis larvae in imported deep-frozen whole Atlantic mackerel (Scomber scombrus) from FAO 27 to Turkey and smoked Norwegian farmed Atlantic salmon fillets (Salmo salar) between 2018 and 2019. A total of 100 whole Atlantic mackerel and 180 Atlantic salmon fillets were randomly sampled from local Turkish supermarkets. No Anisakis larvae were detected in smoked Atlantic salmon fillets. In total, 827 Anisakis larvae were found in mackerel, and the prevalence was 68% (68/100). The mI and mA of Anisakis larvae in mackerel were 13.1 and 8.2, respectively. Whereas the 95.28% (788/827) of the Anisakis larvae were found in abdominal cavity/viscera, the 4.72 % (39/827) of the larvae in the muscle. The prevalence and mI of Anisakis larvae in the abdominal cavity/viscera and muscle of mackerel was 63.0% (63/100) and 42.0% (42/100), and 12.5 and 0.9, respectively. The subsample of 100 larvae was molecularly identified by ITS RFLP patterns. The 99 (99.0%) larvae were identified as A. simplex (s.s.), and 1 (1.0%) larva was A. pegreffii. Consequently, there is low or no risk of anisakiasis in smoked farmed Atlantic salmon for Turkish consumers. The 42.0% prevalence of zoonotic Anisakis species larvae in imported Atlantic mackerel fillets could have public health risk in Turkish consumers for anisakiasis or allergy.

Türk Süpermarketlerindeki İthal Balıklarda Zoonotik Anisakis Larvalarının Varlığına İlişkin Devam Eden Veriler: Dondurulmuş Atlantik Uskumru (Scomber Scombrus) ve Füme Atlantik Somonu (Salmo Salar)

Öz

Anisakis pegreffii ve A. simplex sensu stricto (s.s.) türleri insan anisakiasisine neden olan ana etiyolojik ajanlardır. Bu çalışmada Anisakis larvalarının varlığı 2018-2019 yılları arasında FAO 27 avcılık sahasında avlanıp ve sonrasında Türkiye'ye ithal edilen derin dondurulmuş bütün Atlantik uskumru (Scomber scombrus) ve tütsülenmiş Norveç çiftlik Atlantik somon filetolarında (Salmo salar) pepsin sindirim yöntemine göre araştırılması amaçlanmıştır. Toplam 100 bütün Atlantik uskumru ve 180 Atlantik somon filetosu Türk süpermarketlerinden örneklendi. Füme Atlantik somon filetolarında Anisakis larvası tespit edilmedi. Uskumruda toplam 827 Anisakis larvası bulunmuş olup, larvaların enfeksiyon oranı %68 (68/100) olarak saptanmıştır. Uskumruda Anisakis larvalarının ortalama yoğunluk (mI) ve ortalama bolluk (mA) değerleri sırasıyla 13,1 ve 8,2 idi. Anisakis larvalarının %95,28'i (788/827) karın boşluğu/iç organlarında bulunurken, larvaların %4,72'si (39/827) kaslarda bulunmuştur. Anisakis larvalarının uskumrunun karın boşluğu/iç organları ve kasındaki enfeksiyon oranı ve mI değerleri sırasıyla %63,0 (63/100) ve %42,0 (42/100) ile 12.5 ve 0.9 idi. Çalışmada örneklenen 100 larva moleküler olarak ITS RFLP desenlerine göre teşhis edildi. Araştırmada 99 (%99,0) larva A. simplex (s.s.) ve 1 (%1,0) larva A. pegreffii olarak teşhis edildi. Sonuç olarak Türk tüketiciler için tütsülenmiş çiftlik Atlantik somonunda anisakiasis riski düşüktür veya hiç yoktur. İthal Atlantik uskumru filetolarındaki zoonotik Anisakis türü larvalarının %42,0 oranındaki yaygınlığı Türk tüketicilerde anisakiasis veya alerji açısından halk sağlığı riski oluşturabilir.
