Fake-seafood producers are pushing back against laws requiring accurate labeling

March 18, 2020 — Genetically tweaked salmon that grow three times faster than normal fish. Fillets grown in labs from fish cells. Now plant-based seafoods such as “vegan shrimp,” or “Toona,” are gaining footholds in the marketplace – and confusing customers.

A new study by FoodMinds for the National Fisheries Institute showed that about 40 percent of consumers believed plant-based imitations contain actual seafood. Up to 60 percent thought the products had similar nutritional content as real fish. Still, fake-seafood producers are pushing back against more accurate labeling, claiming without any evidence that customers know what they are getting.

“We have to ensure that the labels are educating people about something as simple as what’s in the package. A lot of these plant-based alternative makers have even suggested that they have the ‘first amendment right’ to call their products whatever they want. And that’s simply not the case,” said Gavin Gibbons, NFI vice president for communications.

Study details mislabeling of North Carolina shrimp

September 10, 2019 — A third of shrimp labeled “local” wild shrimp in North Carolina was actually imported farmed shrimp, a new study found.

A forensics sciences class at the University of North Carolina at Chapel Hill obtained shrimp samples from 60 grocery stores and seafood markets across the state, and found that 35 percent mislabeled local shrimp at least once. That is consistent with the mislabeling rate on shrimp nationwide, the students wrote in the article published on BioRxiv.

Are these shrimp actually local? Falsely labeled seafood coming to forefront in North Carolina.

August 30, 2019 — Seafood may be labeled as local from North Carolina, but often it actually comes from Asian ponds and arrives infused with harmful supplements, according to a new study.

A third of the shrimp marked as harvested from North Carolina waters likely was farm raised in a foreign country with fewer laws and oversight, according to a new study by the University of North Carolina.

Members of the study group bought 106 shrimp from 60 vendors, including 14 in Dare County and 15 in Hyde County. DNA tests determined the species.

The study highlights a practice where companies falsely label foreign seafood as local to sell at higher prices, double the amount in some cases.

“Consumers deserve to know what they’re getting,” said Glenn Skinner, executive director of the North Carolina Fisheries Association. “We feel strongly this should not be going on.”

Seafood fraud a hot topic at US restaurant show

May 21, 2019 — Seafood fraud is a hot topic at the ongoing National Restaurant Show, taking place from 18 to 21 May in Chicago, Illinois, U.S.A.

Celebrity chefs Barton Seaver, Rick Bayless, and Andrew Zimmern all touched on the topic during public appearances at the show, as did executives from several top foodservice companies.

“The seafood industry as a whole is ill-served and everyone loses when seafood fraud happens,” Barton Seaver, a chef, author, and founder of the Coastal Culinary Academy, told SeafoodSource at the event, which is the largest U.S. restaurant show.

Seaver spoke on a panel about seafood mislabeling and sustainability along with Bayless, who is the chef and owner of Frontera Grill and other restaurants, and Josephine Theal, director of category management for food and hospital management firm Delaware North.

“We as operators create an environment in which fraud can profit,” Seaver said. “If I as a chef am only willing to buy cod, then I’ve created a situation where pollock needs to become cod,” Seaver said. Some restaurants are okay with buying the “flaky white fish of the day” and labeling it “cod,” Seaver added.

Science on your side: The trappings of fish fraud

April 18, 2019 — Seafood fraud and mislabeled seafood is a permanent topic in the sustainable fisheries space and has been driving the demands for product traceability. Since 2011, Oceana has led the discourse on fish fraud by publishing sixteen reports on the subject.

Oceana Canada’s 2018 report exposed some important shortcomings in the Canadian seafood system and offered constructive, achievable mandates for reducing seafood fraud domestically, but the study collected data from a biased sample and only presented results that supported a narrative of rampant fraudulence.

Oceana collects seafood samples at restaurants and retail outlets, DNA tests them, then matches the DNA results to government labeling guidelines. The sampling focused specifically on cod, halibut, snapper, tuna, salmon and sole because these species historically, “have the highest rates of species substitution.” This nonrandom sampling is consistent with previous seafood fraud studies from Oceana.

Of the 382 seafood samples tested in Canada, 168 (44 percent) were found to be mislabeled.

None of the red snapper (Lutjanus campechanus), yellowtail or butterfish tested was appropriately labeled. Tuna was mislabeled 41 percent of the time, halibut 34 percent, cod 32 percent and salmon 18 percent.

Fundamental to the interpretation of the Oceana Canada 2018 study’s results is the understanding that the samples were selected to find fraud, not to measure the actual extent of fraud across the entire seafood supply chain. Oceana disclosed this in the report. However the press release it issued for this report, and subsequent headlines from other news sources, such as “At least one quarter of the seafood you buy is a lie” from the site IFL Science, created a different narrative.

Aside from the sampling criticisms, the analysis of specific species was especially flawed.

The fish you’re eating in London might not be what it’s labelled

April 16, 2019 — When biology professor Jennifer McDonald got the DNA results back from her students’ experiment on fish, a high number of the fish were not what was said on the label.

As part of a class experiment at Fanshawe College, her students were sent to grocery stores and sushi restaurants in London to collect fish samples.

The class extracted the DNA and compared how many samples were actually what they claimed to be.

Of the 16 samples, they were able to sequence nine of them due to varied success rates.

Seven of the nine were misidentified, McDonald said.

“Yeah, it was a pretty high number,” she said.

A piece of fish that was labelled as red snapper came back as tilapia, something McDonald said happens all the time.

“That really wasn’t surprising. It was disappointing but not surprising,” she said. “Same with a piece of fish that was supposed to be white tuna. That is very often actually escolar and mislabelled as white tuna.”

What did surprise McDonald was when tilapia was passed off as red tuna.

“A fish like tuna has a very characteristic taste it has a very characteristic texture and for a place to actually be fooling people into thinking that they’re eating tuna when they’re really being served tilapia was really really surprising,” she said.

MSC research counters findings of other mislabeling studies

March 26, 2019 — A new Marine Stewardship Council study has found mislabeling of its certified seafood is lower than the average of several other recent studies, which claim to have detected seafood mislabeling rates as high as 30 percent.

MSC’s expansive analysis of 1,402 MSC-certified fish products from 18 countries found that fewer than 1 percent of MSC-labeled seafood products were mislabeled.

The results were published in the journal Current Biology.

“There is widespread concern over the vulnerability of seafood supply chains to deliberate species mislabelling and fraud. In the past, this has included some of the most loved species such as cod being substituted by farmed catfish, which can seriously undermine consumer trust and efforts to maintain sustainable fisheries,” the lead of author of the paper, the MSC’s Jaco Barendse, said in an MSC press release.

The MSC’s ecolabeling and Chain of Custody program is an effective deterrent for systematic and deliberate species substitution and fraud, the organization said.

In the new study, the largest and most comprehensive assessment of MSC-labeled products, MSC worked with laboratories of the TRACE Wildlife Forensics Network and SASA’s (Science and Advice for Scottish Agriculture) Wildlife DNA Forensic unit to employ DNA barcoding.

Of the 1,402 seafood products tested, 1,389 were labeled correctly and 13 (0.92 percent) were not. Mislabeled products were found in fresh and frozen pre-packed products and in restaurants, mainly in Western Europe, with one case in the U.S. All cases of mislabeling were identified in whitefish (such as cod, hake, and hoki) and flatfish products.

Seafood Fraud: Is your hake fake? Not if it’s ecolabeled!

March 19, 2019 — The following was released by the Marine Stewardship Council:

DNA barcoding of more than 1400 Marine Stewardship Council (MSC) labelled products has shown that less than 1% were mislabeled, compared with a reported average global seafood mislabeling rate of 30 percent. These results published in the journal Current Biology suggests that the MSC’s ecolabeling and Chain of Custody program is an effective deterrent for systematic and deliberate species substitution and fraud.

The MSC is a global non-profit that sets a benchmark for sustainable fishing and traceable supply chains. If fisheries and supply chain companies get certified, they can use the MSC’s blue fish label on products in stores, on fresh fish counters and on restaurant menus.

Species identification

“There is widespread concern over the vulnerability of seafood supply chains to deliberate species mislabeling and fraud. In the past, this has included some of the most loved species such as cod being substituted by farmed catfish, which can seriously undermine consumer trust and efforts to maintain sustainable fisheries,” said Jaco Barendse, Marine Stewardship Council and lead author on the paper

DNA methods have been widely used to detect species mislabelling and a recent meta-analysis of 4500 seafood product tests from 51 peer-reviewed publications found an average of 30 percent were not the species stated on the label or menu In the present study, the largest and most comprehensive assessment of MSC-labeled products, the MSC worked with laboratories of the TRACE Wildlife Forensics Network and SASA’s (Science and Advice for Scottish Agriculture) Wildlife DNA Forensic unit to employ DNA barcoding to identify the species in 1402 MSC certified fish products from 18 countries.

They found that 1389 were labeled correctly and thirteen were not. This represents a total rate of less than 1% (0.92) species mislabeling in contrast to the global average of 30%. Mislabeled products were found in fresh and frozen pre-packed products and in restaurants, mainly in western Europe, with one case in the USA. All cases of mislabeling were identified in whitefish (cods, hakes, hoki) and flatfish products.

Mislabeling or fraud?

There are many reasons that mislabeling may occur. Unintentional mislabeling can result from misidentification of species when the fish is caught, mix-ups during processing, or ambiguities in product naming, such as the use of catchall trade names such as ‘snapper’ or ‘skate’.

Fraud, on the other hand, occurs when there is intentional substitution mainly for financial gain. This is typically when a higher value species is substituted with one of lower value. Fraud may also arise when species from unsustainable or illegal fisheries gain access to the market by passing them off as legally caught fish.

While DNA testing can identify cases of species substitution, on its own it cannot confirm whether this was fraud. To do this it is necessary to trace the product’s movement back through the supply chain to identify the exact step where the issue occurred.

The MSC’s Chain of Custody certification requires that every distributor, processor, and retailer trading certified seafood has a documented traceback system that maintains separation between certified and non-certified seafood, and correctly identifies MSC products at every step.

For the thirteen mislabeled products, records were obtained from each company at each step in the supply chain. Trace-backs revealed that only two mislabeled samples could be confirmed as intentional substitutions with species of non-certified origin. MSC certified products can command higher prices and better market access than non-certified products therefore these substitutions were likely to be fraudulent. Those responsible for the substitutions had their MSC certificates suspended. There were other instances where substitutions inadvertently occurred at the point of capture or during onboard processing – likely due to misidentification between closely related, similar-looking species that co-occur in the catch. There was no discernible financial motive.

“The use of DNA tools to detect substitution in the fish supply chain is well-documented but until now has essentially revealed a depressing story. Our research flips this on its head and demonstrates how we can apply similar technology to validate the success of eco-labels in traceable, sustainable fishing,” said Rob Ogden, TRACE Wildlife Forensics Network and University of Edinburgh.

Next steps

MSC certificates apply only to fish stocks and fisheries, and not entire species. Although MSC Chain of Custody Certification requires separation of MSC and non-MSC certified products, there remains a risk for possible deliberate substitution between certified sustainable and other fish of the same species.

Francis Neat, Head of Strategic Research at the MSC said “While we can get a good indication of whether species-level substitution is taking place, using DNA barcoding and tracebacks, the future for the MSC is to invest in state-of-the-art next generation gene sequencing and isotopic and trace element profiling. This will make it possible to determine which stock a fish product came from, in addition to whether it is the species mentioned on the packaging.”

Your sea bass might be tilapia, report warns

March 8, 2019 — The incidence of seafood fraud still remains high despite more consumer awareness about the issue.

A report released Thursday morning from a nonprofit group finds that roughly 20 percent of seafood products it tested were mislabeled, deceiving customers about everything from where the fish was caught to the type of fish they are eating.

Oceana, an international organization focused on ocean restoration, started investigating the issue in 2010, testing almost 2,000 samples from 30 states for DNA identification and finding that around one-third of the samples tested were mislabeled.

“It never ceases to astonish me that we continue to uncover troubling levels of deception in the seafood we feed our families,” said Kimberly Warner, one of report’s authors.

The discovery comes at a time when seafood consumption among Americans is at a high and the U.S. is importing approximately 90 percent of the seafood it consumes.

What is seafood fraud? Dangerous and running rampant, report finds

March 7, 2019 — If you order a filet of snapper at a restaurant, you probably expect to be served snapper. But a new report suggests there’s a strong chance you’ll be getting something else.

Oceana, a marine conservation nonprofit with a recent history of studying seafood mislabeling, today published a new report on the state of seafood fraud in the U.S.

They found that 20 percent of the 449 fish they tested were incorrectly labeled. Orders of sea bass were often replaced by giant perch, Alaskan halibut by Greenland turbot, and Florida snapper by lavender jobfish, to name a few.

Oceana made headlines in 2016 by publishing a report finding massive seafood fraud on a global scale. Since then, NOAA created the Seafood Import Monitoring Program (SIMP), to track 13 species deemed at high risk of being fraudulently sold or sourced illegally.

None of the 13 SIMP monitored species were sampled.

“We wanted to highlight that there are other species other than the high-risk species,” says Kimberly Warner, a senior scientist at Oceana and one of the report’s authors.
