Despite high effort for food traceability to ensure safe and sustainable consumption, mislabeling persists on seafood markets. Determining what drives deliberate fraud is necessary to improve food authenticity and sustainability. We analyzed samples of fish highly consumed in Europe and worldwide i. Results revealed low mislabeling rate 1. Furthermore, the use of endangered what is the meaning of investigation in food science e.

These findings reveal a worrying intentional fraud that hampers the goal of sustainable seafood production and consumption, and suggest to prioritize control efforts on highly appreciated species. It is especially important to obtain food directly from natural populations, by hunting, fishing or harvesting. Only knowing their real exploitation level can the natural populations be sustainably managed. When a species is sold for another, the substitute is exploited without reporting.

Moreover, if the substitute species is cheaper, the consumer will pay an unfair higher price for the product they believe is consumed. In some marine species as the Atlantic cod Gadus morhua mislabeling is decreasing 6 while in others like hake it has oscillated over the last decades and seems to be increasing in the last years 7. DNA analysis is widely used for becoming increasingly affordable, even when multiple markers are needed 189.

Not always mislabeling is synonymous of fraud. Sometimes it is accidental, for example when different species are caught together in mixed fisheries and cannot be distinguished easily from morphology, as megrims of the genus Lepidorhombus or several hakes of the genus Merluccius In other cases, however, mislabeling is deliberate so it can be considered fraudulent. In contrast with accidental mislabeling, deliberate mislabeling is more frequent in unrecognizable versus recognizable products 11 In recognizable products the head is present and the whole body contains morphological characteristics that serve to identify the species, while the species cannot be ascertained visually in unrecognizable products.

Often substitute species are cheaper than the original one 1314 ; fraudulent seafood mislabeling of economic cause happens against the interest of the consumer. Examples are the covered exploitation of protected species, e. In the control of deliberate mislabeling, a priority is to determine the point of the commercial chain and the type of product where it happens more frequently 20 ; that is to know mislabeling niches for control to be reinforced therein Apparently, it is especially frequent in highly appreciated products, like sushi 22processed cod products 23scarce and expensive Bluefin tuna Thunnus thynnus that is commonly replaced by other tuna species 24 In other words, defrauders sell what the consumer wants whether the product is real or not.

However, fraudulent mislabeling having an important economic component, defrauders will substitute preferentially, if not only, expensive species. This country was chosen for having been identified as one of the countries with highest seafood consumption We considered two species pairs of blue and white fish, one cheap what to do if your ethernet cable isnt working one expensive from each type.

Expectations were: First, in deliberate why the internet is not reliable a higher proportion in not recognizable versus recognizable products and expensive versus cheap species Hypothesis a. In total we analyzed genetically fish samples commercialized by European companies, obtained from 11 stores. The sequences of the genetic barcodes were aligned within species, and the haplotypes sequence variants submitted to GenBank, where they are available with the accession numbers MWMW for control region barcodes and MWMW for COI barcodes.

Mislabeling was found in seven samples, 1. Mislabeling was significantly more frequent in not recognizable products 10 out of 11 mislabeled products, Table 2and in expensive species that are tuna and hake in this region only two anchovies and none blue whiting. Mislabeling risk ratio RR of non recognizable versus recognizable products was 1. Similarly, mislabeling RR of expensive versus cheap species was 1. A deeper view at the mislabeled products Table 2 suggests that the mislabeling found in this study could be compatible with IUU, at least in some cases.

Mislabeled anchovies were about 12—13 cm long, and substitute species were small tuna fry or juveniles, one identified from DNA as yellowfin Thunnus albacares the capture region stated on the label was NE Atlanticand the other as Thunnus alalunga captured from the Aegean Sea in the Mediterranean basin. The first one was sold whole, in fresh, eviscerated but with head and tail thus it was recognizable; the other was frozen headless, tailless and eviscerated.

Small tuna fry and adult anchovies are love quotes in kannada written in english morphologically different but could be confounded by non-expert consumers, especially when sold headless. Engraulis encrasicolus distribution overlaps with spawning areas of Thunnus albacares in northeast African waters, and with those what is the meaning of investigation in food science Thunnus alalunga in the Mediterranean Sea, thus these substitutions are compatible with capturing tuna juveniles while fishing anchovy.

Three of them were substituted by M. South African M. Thus the cause of this particular substitution is compatible with IUU without discarding substitution in a later step. The other mislabeled hake was substituted by north Atlantic cod Gadus morhua which distribution does not overlap with south African hakes, thus substitution during fishing or landings was not possible in this case and must have occurred later in the commercial chain Table 2.

The three products that were substituted by northern Bluefin tuna Thunnus thynnus Table 2 were all unrecognizable slicesbut the fish body without the head was visible and slices were cut fresh in front of the customer. They were sold in two different stores. The other two mislabeled samples did not report the capture region on the label. All the species overlap in the north—center east Atlantic and the EU has strict fishing quotas T.

The raw dataset can be found in Rodriguez et al. A clear difference between species was found regarding consumption levels Fig. Tuna and hake were consumed weekly and monthly by a much larger proportion of participants than anchovy and whiting. Consumption of the four species. Since the average fish consumption frequency in the region was 3.

Mislabeling was significantly correlated with both price Fig. Linear what does it mean never a dull moment with their r 2 value for slope different from 0 are presented. The relationships between these variables are summarized in Fig. Mediation effect of price between consumer appreciation and mislabeling was thus significant in spite of limited number of species analyzed.

Arrows represent relationships between variables. Combining a suite of molecular tools three DNA markers and four different protocols and a social survey amongst consumers, this work showed several evidences of fraud in appreciated species that are important for both food sciences and conservation. The mislabeling found in this study was likely fraudulent, since, according to hypothesis aits what is the meaning of investigation in food science was significantly higher in expensive than in cheap species, and in not recognizable than in recognizable products.

This result points at the need of focusing on highly consumed highly priced species as priority mislabeling niche. Inadvertent mislabeling due to simple morphological confusion between species, frequently reported in previous studies in Spain 10does not seem the main cause of mislabeling here. As in other studies, mislabeling occurred in tuna and hake. The level found was comparable to that published by other authors in Spain and elsewhere. Sotelo et al. Gordoa et al. It is possible that mislabeling is decreasing in Spain in the last years, following the current trend of improvement of market operations pointed out by Mariani et al.

Thunnus albacares and T. This reverse substitution expensive T. All together our results would indicate a change in tuna mislabeling trends in Spain. Decrease of hake mislabeling seems to be happening in Europe as well, and the increase of the last years found in Blanco-Fernandez et al. A difference with past mislabeling reports was the main substitute species found here, the Benguela hake Merluccius pollirarely found as a substitute in other studies 7.

This would imply a change in hake substitutes and the unreported introduction of this species in European markets. Anchovy mislabeling in Europe has been reported before To our knowledge this is the first time that Thunnus is reported as a substitute of anchovy products. As in hake and tuna, it seems that the mislabeling what does are you 420 friendly mean are changing in this country towards what is set theory with examples substitute species.

Although from our data and other studies 6 fish mislabeling seems to be decreasing in Spain, the substitute species of this study are of concern for conservation because they point at the involvement of IUU, one of the causes of fraud identified by Fox et al. Finding small juveniles of near-threatened Thunnus albacares and T. If they catch juveniles what is the meaning of investigation in food science other species as by-catch, they are not sufficiently selective of the target species.

Being true that the proportion was small, about 2. On the other hand, the use of endangered Thunnus thynnus and perhaps the vulnerable Thunnus obesus too in substitution of less threatened tuna species is, definitively, a call of attention for the increase of control in European tuna markets, as demanded by other researchers Since the catch areas of label and substitute species what is the meaning of investigation in food science, these substitutions would suggest that Bluefin tuna caught over quota is being sold as another species.

Finally, Merluccius polli —main substitute of M. Introducing the species as a substitute in European markets impedes traceability of its catch. It could be introduced at industrial level for example to complete a batch of slices or filletsor be another example of the use of unregulated fishing products. Selling M. In conclusion, these results reaffirm a general trend of decreasing mislabeling rates, which is to be expected as efforts in food sciences for better traceability continue. However, while inadvertent substitutions decrease, special attention must be directed towards the detection of deliberate fraud.

The found substitutes are an indication for IUUs as a source for fraud. This is a cause for concern and calls for a focus on products that are especially susceptible to these actions; i. Moreover, the whole SDG 12 is undermined if conscious consumers cannot be sure of eating really their choice of sustainably caught fish. This study adheres to good research practices based on the European code of conduct for research integrity All methods were performed in accordance with relevant guidelines and regulations.
