“…Considering the prevalence and abundance registered, all of them could represent a high risk of infection when consumed raw, marinated or poorly cooked, if not being adequately frozen beforehand. In general, this observation is in accordance with other results previously reported [20][21][22][23][24][25][26][27][28][29][30].…”

“…The blue whiting is one of the main fin fish species consumed in Spain [32], due to its low cost and its easy mode of preparation. The same goes for the European hake, another of the fin fish analysed in which a significant prevalence was detected, also reported by other authors [23][24][25]. The silver hake, of which there are scarcely similar studies in the literature [23], had a high prevalence, although the abundance was lower in comparison to the other "high risk" species.…”

Anisakidosis is a fish-borne zoonosis caused by parasitic nematodes of the family Anisakidae, of which the species belonging to Anisakis simplex complex are the most representative. It is considered an emerging disease in Spain. The objective of this study is to analyse the presence of larvae in fish frequently consumed in Spanish supermarkets, inferring the risk of infection. In total 1,786 specimens of 9 different fish species, from two geographical origins (Atlantic and Mediterranean), acquired fresh and not eviscerated were examined for anisakid nematodes. Analysis showed that 33.7% of the samples were parasitized by Anisakis larvae. The horse mackerel (Trachurus trachurus) presented the highest total prevalence (66.0%), followed by the silver hake (Merluccius bilinearis) (59.5%), the mackerel (Scomber scombrus) (58.4%), the blue whiting (Micromesistius poutassou) (53.9%) and the European hake (Merlucius merlucius) (45.0%). In general, the prevalence was higher in Atlantic than in Mediterranean fish. In all the species analysed, a higher presence of the parasite was detected in the viscera than in the flesh, although in the most parasitized species a noteworthy prevalence and abundance was observed in the flesh. In conclusion, risk factors, like fish species and origin, should be considered by consumers, in addition of following the recommendations established by Commission Regulation (EU) No1276/2011 and the Spanish Royal Decree 1420/2006.

“…The health risk posed by both sibling species should be assessed by more frequent use of molecular specific diagnosis in clinical cases of anisakiosis. The results of this study also highlight hake consumption as a risk factor for the disease, as this species of fish can be heavily parasitized [27,30]. Consumers should therefore be warned of the risk of consuming undercooked fish and be better informed of the recommendations to follow.…”

“…In fact, in the epidemiological studies on hake from North-East Atlantic and Mediterranean, A. simplex (s.s.) was not found in the Mediterranean hosts [26]. Although it can be heavily parasitized, North-East Atlantic hake is highly appreciated by consumers [27].…”

“…The sibling species A. pegreffii, on the other hand, is endemic to the Mediterranean Sea, but has also been reported in fish caught off the North-East Atlantic coast [8,26]. Compared to Atlantic fishes, those from the Mediterranean have a lower parasitic load in terms of anisakid larvae, but both are readily available on the market [26,27]. All patients in our study live in the Mediterranean area, yet the identification of A. simplex (s.s.) as the causative agent suggests that the hake consumed was caught in the North-East Atlantic region.…”

Anisakiosis is a fish-borne disease with gastrointestinal and/or allergic symptoms caused by the consumption of raw or undercooked fish parasitized with nematode larvae of the genus Anisakis. In Europe, Anisakis pegreffii has been detected as the causative agent, although the sibling species Anisakis simplex sensu stricto (s.s.) is also known to cause the disease in other parts of the world, and discrepancies exist regarding their respective pathogenic potential. In Spain a high number of cases has been recorded, with marinated anchovies being the main source of infection, although no specific diagnosis has been documented in humans. In this study, we analyzed three cases of anisakiosis in patients from Barcelona (Spain) who had consumed undercooked hake. All patients described epigastric pain and several larval nematodes were removed endoscopically from their stomachs. Larvae were morphologically characterized as third-stage larvae of Anisakis simplex sensu lato (s.l.) and molecularly identified as A. simplex (s.s.) by means of PCR RFLP of the ITS region of the rDNA and sequencing of the elongation factor1 alpha1 (EF1 α-1) nDNA gen. This study represents the first specific identification of Anisakis larvae in clinical cases of anisakiosis reported in Spain. Specific molecular diagnosis is of crucial importance for assessing the health risk of Anisakis sibling species. Hake consumption stands out as a risk factor for anisakiosis, since this fish species can be highly parasitized.
