FAO Symposium Discusses the Future of Fisheries and Global Food Security

December 4, 2019 — Organized by the Food and Agriculture Organization of the UN (FAO), the International Symposium on Fisheries Sustainability discussed opportunities to reform the capture fisheries sector to contribute to global food security, eradicate hunger, promote gender equality, and achieve the SDGs. At the event, the High Level Panel on the Sustainable Ocean Economy released a blue paper that analyzes the current status and future potential of food production from the ocean.

The Symposium convened from 18-21 November 2019, in Rome, Italy. The Forum focused on the theme, ‘Strengthening the Science-Policy Nexus’ and aimed to identify pathways to strengthen the science-policy interface in fisheries production, management and trade based on sustainability principles. Panelists discussed opportunities for the fisheries sector to respond to challenges and support the 2030 Agenda for Sustainable Development and the UN Decade of Ocean Science for Sustainable Development (2021-2030).

The High Level Panel released a paper titled ‘The Future of Food from the Sea,’ at the Symposium. The paper finds that the ocean could provide more than six times the food it does today with improved management and technological innovation. In comparison with current fishing projections, the report stresses that reforming the world’s capture fisheries by ending overfishing and improving global fisheries management could result in 20% more catch compared to today and 40% more fisheries catch than current projected future catch. This amount is over two-thirds of the animal protein needed to feed projected future global populations. In addition, the paper emphasizes “highly nutritious nature of seafood,” which contains essential vitamins, minerals, omega-3 fatty acids and other nutrients not contained in terrestrial animal proteins or plant-based foods. The report also highlights the potential of the sustainable expansion of marine aquaculture to enhance food security and help eradicate hunger, in line with the SDG 2 (zero hunger).

Everybody knows to avoid tuna when pregnant, right? Not so fast. Eating tuna might actually yield better results, says a large new study.

November 26, 2019 — Eating ocean fish is good for you, but some fish have significant levels of methylmercury which is bad for you, so you should avoid those fish, right? Wrong, says a new study.

Mothers who ate seafood, even when it contained high levels of methyl mercury, had smarter kids than those who didnʻt eat seafood, says the comprehensive, peer-reviewed study.

“Moderate and consistent evidence indicates that consumption of a wide range of amounts and types of commercially available seafood during pregnancy is associated with improved neurocognitive development of offspring as compared to eating no seafood,” it said.

This flies in the face of conventional wisdom, and some medical wisdom. Both the U.S. Environmental Protection Agency and the U.S. Food and Drug Administration recommend against pregnant women eating ahi, over concerns about methyl mercury exposure.

There is no question that thereʻs methylmercury in yellowfin, bigeye and bluefin tuna, and that the amount has been increasing in recent years. There are also significant amounts of mercury in blue marlin and other species.

The Hawai`i Department of Health warns against pregnant women eating any blue marlin, swordfish and shark and recommends severe limits on consumption of tunas.

For Your Heart, Eat Fish Or Take Pills? Now There’s A Drug Equal To 8 Salmon Servings

November 25, 2019 — It’s long been known that eating fish — especially cold-water fish such as salmon that are rich in omega-3 fatty acids — is good for heart health.

But, for the millions of Americans who are at high risk of heart disease, eating enough fish to make a difference isn’t likely to be realistic for most.

There’s growing evidence that taking a very high dose of purified fish oil, delivered in a prescription pill, can help prevent heart attacks and strokes among people who have elevated risks. The amount of fish oil in the daily recommended dose of the pill is the equivalent of eating about eight to 10 servings of salmon a day.

In early November, an advisory panel to the FDA voted unanimously to approve expanded use of the prescription drug, Vascepa, which is made from one type of omega-3 fatty acid, called eicosapentaenoic acid, or EPA for short. The oil is extracted from sardines and anchovies, and then purified.

Currently, Vascepa is already approved for use in people with very high levels of triglycerides — which is a type of fat in the blood. (You can check your triglycerides as part of a cholesterol screening.)

FDA Investigation of Scombrotoxin Fish Poisoning Linked to Yellowfin/Ahi Tuna/gassed tuna

November 20, 2019 — The following was released by the U.S. Food and Drug Administration:

FDA and state health authorities are investigating incidents of scombrotoxin fish poisoning linked to yellowfin tuna, also sometimes called ahi tuna. As a result of this investigation, FDA has placed Truong Phu Xanh Co, LTD of Vietnam on Import Alert, which provides information to FDA field staff that they may detain the firm’s yellowfin tuna without physical examination. Detained product will not enter the United States unless the importer proves that it meets U.S. food safety standards.

FDA asked for the supplier of yellowfin tuna associated with most of the illnesses, Truong Phu Xanh Co., LTD of Vietnam, to initiate a voluntary recall of all of its imported yellowfin tuna with production dates from January 2019 to the present. At this time, the firm has not recalled any product.

As part of the investigation, FDA evaluated the firm’s Hazard Analysis and Critical Control Point (HACCP) Plans. A HACCP Plan details a firm’s management system to address food safety through the analysis and control of biological, chemical, and physical hazards. Since FDA’s evaluation of this plan identified deficiencies, we asked for Truong Phu Xanh Co., LTD of Vietnam to initiate a voluntary recall of all of its imported yellowfin tuna with production dates from January 2019 to the present.
 
The investigation has identified 47 illnesses of scombrotoxin fish poisoning that occurred between August 8, 2019 and October 15, 2019.
 
Throughout the investigation, FDA and states have also been collecting product samples for testing. Scombrotoxin fish poisoning occurs when fish begin to spoil, resulting in increased histamine levels. Therefore, product samples cannot be linked to case patient samples through Whole Genome Sequencing (WGS) or Pulsed-Field Gel Electrophoresis (PFGE) analysis like for other foodborne illnesses, e.g., Salmonella or Listeria. Instead, samples are tested for decomposition and/or histamine levels. Multiple samples have been collected and analyzed, with positive results for decomposition or high histamine levels in products imported from Truong Phu Xanh Co., LTD.
 
FDA and state partners collected epidemiologic and traceback information for reported illnesses. As additional epidemiologic and traceback information was collected, FDA and state partners were able to work with companies throughout the supply chain to voluntarily recall implicated product. While recalls were conducted at various points in the supply chain, there may be additional product still on the market that could cause illness.
 
Ultimately, the coordinated investigation was able to identify Truong Phu Xanh Co., LTD as the common supplier of tuna that was likely consumed by most of the ill people.
 
Because scombrotoxin fish poisoning causes temporary or medically reversible adverse health consequences this incident did not meet the threshold for the use of FDA’s mandatory recall authority.
 
It has been determined that the source of the tuna for the illnesses announced by Seattle-King County Public Health Department is not related to Truong Phu Xanh Co., LTD.
 
Recommendations
 
Yellowfin tuna from Truong Phu Xanh Co., LTD with a production date in 2019 should not be consumed because it may have the potential to cause scombrotoxin fish poisoning. Tuna from this supplier could have been sold thawed or frozen; and could have been sold as ground tuna meat, poke cubes, steaks, or loins; this product could still be within its shelf life.­­
 
Scombrotoxin fish poisoning occurs when fish is not properly chilled or preserved and begins to spoil, resulting in increased histamine levels. Histamine cannot be destroyed by freezing or cooking.
 
Importers, Suppliers, and Distributors:
 
Importers, suppliers, and distributors should not use and should discard or destroy any yellowfin tuna imported from Truong Phu Xanh Co., LTD with a production date in 2019.
 
Restaurants and Retailers:
 
Restaurants and retailers should contact their suppliers to confirm the source of their yellowfin tuna because not all product was distributed in packaging that identifies Truong Phu Xanh Co., LTD. Yellowfin tuna imported from this company with a production date in 2019 should not be used, served, repacked, or sold; and should be discarded.
 
Consumers:
 
While we expect restaurants and retailers will have removed yellowfin tuna with a production date in 2019 from the Vietnamese supplier Truong Phu Xanh Co., LTD, consumers should ask if the yellowfin tuna being served or sold was imported from the Vietnamese supplier Truong Phu Xanh Co., LTD and has a production date in 2019.

Pregnant mothers and children should eat seafood

November 15, 2019 — Two recent studies, Hibbeln et al. 2019 & Spiller et al. 2019, published together in Prostaglandins, Leukotrienes and Essential Fatty Acids (PLEFA), examined the health benefits of consuming seafood during pregnancy. Researchers found that seafood consumption during pregnancy was strongly linked to increased IQ in children.

Thirteen leading dietary scientists spent the last two decades conducting the most thorough review on the subject in history. The research evaluated studies on 102,944 mother-child pairs and 25,301 children.

The findings strongly supported what many consumers already know—seafood is good for you. But the specific measurements to this notion were striking, so much so that one of the authors warned SeafoodNews.com, “There is a lost opportunity for IQ when mothers are not eating enough seafood.”

The study found children gain an average of 7.7 IQ points when mothers ate seafood during pregnancy, compared to mothers that did not eat seafood. Another finding showed that children born from mothers who did not eat seafood during pregnancy were three times more likely to be hyperactive.

Uncle Sam wants you to eat more shark

November 5, 2019 — The following was released by The New Food Economy:

Late last month, the National Marine Fisheries Service (NMFS) sent out a newsletter featuring a potentially surprising piece of advice: For a sustainable source of protein, try eating shark sometime. NMFS is an arm of the federal science agency, National Oceanic and Atmospheric Administration (NOAA), and it’s responsible for protecting fish populations and their ocean habitats.

“While overfishing has greatly depleted some shark populations overseas, U.S. shark fisheries are some of the most sustainable in the world,” it read. I did a double take, racking my memory for the last time I saw shark as an option at the grocery store or on a restaurant menu. The press release seemed to run contrary to my general sense that shark populations were in jeopardy everywhere.

In August, for example, scientists warned that levels of the popular shortfin mako shark in the Atlantic ocean—for which NMFS has catch limits—are so overfished that they would require until 2045 to fully recover, even if a total harvesting ban was enacted. In July, the Animal Welfare Institute published its annual directory of restaurants whose menus include dishes made from shark fin, rising demand for which contributes to declining shark stocks. And in 2013, researchers issued this dire warning: Commercial fisheries kill approximately 100 million sharks every year, far faster than the rate at which sharks can repopulate.

GOAL: “Antibiotic-free” certification for seafood likely to crop up soon

October 24, 2019 — The use of antibiotics in aquaculture will likely become an increasingly important issue, according to a panel of experts at the 2019 GOAL Conference in Chennai, India.

The panel discussion followed a sobering presentation by Ramanan Laxminarayan – the founder and director at the Center for Disease Dynamics, Economics, and Policy – that detailed the growing risk that antibiotic-resistant bacteria is posing to health. By 2050, if effective methods of controlling antibiotic resistant bacteria are not found, roughly 10 million people could die annually.

New Scientific Paper Shows Seafood Consumption Critical for Brain Development

October 16, 2019 — The following was released by the Seafood Nutrition Partnership:

A new paper published by a group of 13 leading dietary fats scientists highlights the tremendous health benefits from consuming seafood for infant and adolescent brain development. Among the key findings of the systematic review is an average 7.7 IQ point gain in children whose mothers ate seafood during pregnancy compared to mothers who did not eat seafood.

“Relationships between seafood consumption during pregnancy and childhood and neurocognitive development: two systematic reviews” (PLEFA) uncovered 44 scientific studies since 2000 that collectively show the importance of consuming seafood by moms to support the brain development of their babies as well as the need for children to consume more fish and shellfish.

“There is a lost opportunity for IQ when mothers are not eating enough seafood,” the paper’s lead author, Capt. Joseph Hibbeln, MD, Acting Chief, National Institute on Alcohol Abuse and Alcoholism, said at the State of the Science Symposium.

The 13 scientists formed a technical expert collaborative to address two questions posed by the 2020 Dietary Guidelines Advisory Committee (DGAC), and utilized the USDA’s Nutrition Evidence Systematic Review to evaluate the science following the DGAC prescribed review process.

Highlights from the paper, which evaluates studies on 102,944 mother-offspring pairs and 25,031 children, includes:

  • Twenty-four studies reported that seafood consumption among mothers was associated with beneficial outcomes to neurocognition on some or all of the tests administered to their children. The beneficial outcomes appeared on tests administered as early as three days of age and as late as 17 years in age.
  • This scientific review shows children gain an average of 7.7 full IQ points when their moms ate seafood during pregnancy compared to moms that did not eat seafood. The size of benefits for IQ ranged from 5.6 to 9.5 points.
  • In addition to IQ, measures of neurocognitive outcomes included verbal, visual and motor skill development, scholastic achievement, and four specifically looked at hyperactivity and ADHD diagnoses. One finding showed that children of mothers not eating oily seafood had nearly three times greater risks of hyperactivity.
  • Benefits to neurocognitive development began at the lowest amounts of seafood consumed in pregnancy (one serving or about 4 oz per week) and some studies looked at greater than 100 oz. per week. No adverse effects of seafood consumption were found for neurocognition in any of the 44 publications, indicating that there may be no upper limit to seafood’s benefits for brain development.
  • Seafood contains protein, vitamins B-6, B-12 and D, and omega-3 fatty acids that as a whole package contributes to these important outcomes. This systematic review looks at seafood as opposed to any single nutrient.

“The risk is not eating enough seafood — the benefits are so substantial for the development of baby brains, eyes and overall nervous system,” said J. Thomas Brenna, PhD, an author of the paper and a member of the 2015-2020 Dietary Guidelines Advisory Committee.

These findings are consistent with a technical report from the American Academy of Pediatrics earlier this year that emphasized the importance of fish and called attention to the fact that U.S. children are not eating enough seafood. Additionally, Health Canada, the European Food Safety Authority, and World Health Organization have all stated the importance of seafood for brain development.

The authors of the paper, or the technical expert collaborative who conducted the systematic review, include: Capt. Joseph Hibbeln, MD; Philip Spiller, JD; J. Thomas Brenna, PhD; Jean Golding, PhD; Bruce Holub, PhD; William Harris, PhD; Penny Kris-Etherton, PhD, RDN; Bill Lands, PhD; Sonja Connor, MS, RDN, LD; Gary Myers, MD; J.J. Strain, PhD; Michael A Crawford, PhD; and Susan Carlson, PhD. None of the scientists were paid to conduct this review, all were voluntary, and do not have a conflict of interest.

An additional paper, “An abundance of seafood consumption studies presents new opportunities to evaluate effects on neurocognitive development,” published in PLEFA provides more background on the systematic review paper.

Fish Oil Supplements May Do Your Heart Good

October 1, 2019 — Millions of Americans pop a fish oil supplement each day, hoping to bolster their heart health. Now, research suggests they may be on the right track.

The most up-to-date review of data from 13 prior studies found daily omega-3 fish oil supplement use tied to a significant lowering of risk for heart attack, according to a team led by Dr. JoAnn Manson. She is a professor of epidemiology at Harvard’s T.H. Chan School of Public Health, in Boston.

Daily use of the supplement — typically about 840 milligrams per day — was also linked to a lower overall risk of dying from heart disease, the review found.

In total, the 13 studies involved data on more than 120,000 adults, a sample size that is 64% larger than any other yet conducted, the researchers said.

Although the findings are encouraging, fish oil remains just one factor in heart health, Manson said in a school news release.
