Ascaridoid nematodes in horse mackerel, Trachurus trachurus, sold in Spanish supermarkets—Factors able to diminish consumer risk

Anisakid Nematodes and Potential Risk of Human Anisakiasis through the Consumption of Hake, Merluccius spp., Sold Fresh in Spanish Supermarkets

“…The analysis of the fish catching season on larvae parasitization, mainly on Anisakis larvae showed a similar pattern in the three populations of hakes, with the autumn-winter period reaching the highest parasitization parameters, prevalence and mean abundance, compared to the spring-summer period, with or without statistically significant differences. However, these results are not in accordance with those reported in previous studies in this and other fish species previously analysed, which reported mainly, the highest parasitization parameters during the spring season [12,18,22,36,44,45]. Only a few studies reported a higher parasitation in fish caught during the autumn season, such as in the silver hake [1,12].…”

Parasitic Infestations and Infections in Marine Fish (Actinopterygii: Lutjanidae and Mullidae) Marketed in Brazil – An Animal and Human Health Issue

“…Although the anisakids were not found in musculature of fish in the current research, the risks to Public Health cannot be ruled out (Molento et al, 2017;Alves et al, 2020;Debenedetti et al, 2020), mainly due to the immunogenic characteristics of these parasites (Fontenelle et al, 2013). The migration of larvae to the musculature of live or dead fish may occur moments after capture or when fish have been subjected to long periods of storage in boats or markets (Fontenelle et al, 2013).…”

“…chrysurus and L. synagris from the coast of the northeast region of Brazil. Ascaridoid nematodes are among the most abundant helminth parasites of commercially exploited marine fish (Molento et al, 2017;Alves et al, 2020;Debenedetti et al, 2020). The presence of anisakid larvae in the tissues of economically important fish compromises their industrialization process and may have consequences for Public Health due to zoonotic transmission (Molento et al, 2017;Alves et al, 2020;Debenedetti et al, 2020).…”

“…Histopathological analysis provides information about the effects of parasitic infections/infestations on fish, both in the individual and the population context (Johnson et al, 1993;Feist and Longshaw, 2008), reflecting the health of ecosystems (Roberts, 2012). Besides interfering in fish health, some parasites of these vertebrates have zoonotic potential (Barros et al, 2006;Alves et al, 2020;Debenedetti et al, 2020).…”

“…Dias et al (2010) andDebenedetti et al (2020) emphasize the importance of professionals involved in health surveillance, as well as the prior knowledge of fishermen and final consumers about the parasites of fish with zoonotic potential. Health education programs to prevent infection by fish zoonotic parasites should be implemented, especially in coastal cities, such as Recife and Itamaracá cities.…”
