Abstract Surveillance data published since 2010, although limited, showed that there is no evidence of zoonotic parasite infection in market quality Atlantic salmon, marine rainbow trout, gilthead seabream, turbot, meagre, halibut, common carp and European catfish. No studies were found for greater amberjack, brown African catfish, eel pikeperch. Anisakis pegreffii, A. simplex (s. s.) Cryptocotyle lingua seabass, bluefin tuna and/or cod, Pseudamphistomum truncatum Paracoenogonimus ovatus...
Nematodes of the genus Anisakis parasitize many commercial fish species and are responsible for a fish-borne zoonosis (anisakiasis) allergic reactions. can also cause consumer distrust in fishery products economic losses to industry. We review current socioeconomic, legislative, risk management human health problems caused by occurrence discuss possible strategies mitigate them. Visual inspection (and candling) as required EU legislation is not efficient parasite detection. Consequently,...
SUMMARY A multi-marker nuclear genotyping approach was performed on larval and adult specimens of Anisakis spp. ( N = 689) collected from fish cetaceans in allopatric sympatric areas the two species pegreffii simplex (s. s.), order to: (1) identify belonging to parental taxa by using markers (allozymes loci) sequence analysis a new diagnostic DNA locus (i.e. partial EF1 α −1 n region) (2) recognize hybrid categories. According Bayesian clustering algorithms, based those markers, most...
Abstract Parasite biodiversity in cetaceans represents a neglected component of the marine ecosystem. This study aimed to investigate distribution and genetic diversity anisakid nematodes genus Anisakis sampled from Northeast Atlantic Ocean Mediterranean Sea. A total 478 adults pre-adults spp. was identified by multilocus approach (mtDNA cox 2 , EF1 α − 1 nDNA nas 10 gene loci) 11 cetacean species. clear pattern host preference observed for at family level: A. simplex (s.s.) pegreffii...
Species of the genus Pseudoterranova, infect kogiid cetaceans and pinnipeds. However, there is mounting molecular evidence that those from pinnipeds are not congeneric. Here, we provide further non-monophyly members Pseudoterranova phylogenetic analyses conserved nuclear LSU rDNA gene, entire ITS region mtDNA cox2 identify morphological characters may be used to distinguish two clades. We propose resurrection Phocanema, with Ph. decipiens (sensu stricto) as type species, encompass decipiens,...
The Atlantic bluefin tuna Thunnus thynnus is one of the largest and most valuable fish species in Ocean. Its meat highly appreciated worldwide, particularly Japan, where it commonly consumed raw as sushi or sashimi. Here, we investigated occurrence composition parasitic nematodes viscera adult caught off western Norway. zoonotic Anisakis simplex (sensu stricto) pegreffii are reported for first time wild large specimens. Findings suggest that both anisakids appear unable to penetrate stomach...
Microbes play an important role in the degradation of fish products, thus better knowledge microbiological conditions throughout production chain may help to optimise product quality and resource utilisation. This paper presents results a ten-year spot sampling programme (2005-2014) commercially most pelagic species harvested Norway. Fish-, surface-, storage water samples were collected from fishing vessels processing factories. Totally 1,181 assessed with respect quality, hygiene food...
Northeast Atlantic (NEA) mackerel (Scomber scombrus, Scombridae) represents an economically important target for the Norwegian pelagic fishing industry. Despite commercial significance of NEA mackerel, little is known about infections with myxosporean parasite Kudoa thyrsites (Kudoidae). The may cause post-mortem myoliquefaction fish skeletal muscle and therefore reduce quality product. In this study, we examined ‘soft flesh’ occurrence in size groups ‘autumn mackerel’ caught between 2007...
Abstract The objective of this opinion was to determine if any wild caught fish species, originating from specific fishing grounds and consumed in the EU/EFTA could be considered free zoonotic parasites. In Opinion term ‘fishery products’ only refers fresh finfish. As there are multiple species numerous potential parasites, Anisakis sp. used as an indicator parasites marine areas. This parasite is particularly suited it common environments, capable infecting subject majority published...
There is a growing awareness by consumers and food safety authorities regarding the possible presence of parasites or parasite-related potentially hazardous substances in seafood. Anisakis simplex among most frequently occurring wild-caught marine fish. Except for various visual inspection techniques PCR-based methods detection more less intact worms parasite DNA, respectively, there are at present no validated quantification A. proteins processed fish products. This work describes...
The species of Anisakis constitute one the most widespread groups ascaridoid nematodes in marine ecosystem. Three closely related taxa are recognised A. simplex (s. l.) complex, i.e. pegreffii, s.) and berlandi. They distributed populations their intermediate/paratenic (fish squids) definitive (cetaceans) hosts. A panel seven microsatellite loci (Anisl 05784, Anisl 08059, 00875, 07132, 00314, 10535 00185), were developed validated on a total N = 943 specimens pegreffii s.), collected fish...
Northeast Arctic cod, saithe and haddock are among the most important fisheries resources in Europe, largely shipped to various continental markets. The present study aimed map presence distribution of larvae parasitic nematodes Anisakidae family which socioeconomic public health concern. Fishes were sourced from commercial catches during winter or spring southern Barents Sea. Samples fish inspected for using UV-press method while anisakid species identification relied on sequencing mtDNA...
Abstract Members of the myxosporean genus Kudoa occur in various marine teleosts worldwide. Several species are concern to fishery and aquaculture industries as they may produce unsightly cysts fish host’s musculature or associated with postmortem myoliquefaction muscle, commonly referred ‘soft flesh’. This study describes occurrence effects on a host Atlantic mackerel, Scomber scombrus , from northern North Sea. Generalized sp. occurred 0.8% examined fish, i.e. 11 1339 mackerel developed...
