Partnership Among Southeast Alaska Tribes and Universities Is Key to Shellfish Safety
Shellfish toxins are a major problem for Alaskan residents who rely on the bivalves as a subsistence food source and way of life. Harmful algal blooms (HAB) produce toxins that accumulate in shellfish and subsequently pose a hazard for human health. Toxin levels are unpredictable, so residents often face the decision between harvesting shellfish with unknown toxin levels or not harvesting at all.
To address this quandary, the Sitka Tribe of Alaska Environmental Research Lab (STA-ERL) and the Southeast Alaska Tribal Ocean Research (SEATOR) network work to find answers for the subsistence shellfish harvesters. SEATOR partners regularly collect shellfish samples from local beaches and submit them to STA-ERL for toxin analysis.
Some Alaska Native communities rely heavily on shellfish for cultural and commercial reasons, so identifying when and where shellfish may be unsafe is a priority. However, a lot is unknown when it comes to predicting HABs, or what environmental variables cause HABs and affect shellfish safety. The SEATOR network addresses issues of food security for local communities by collecting shellfish samples and observing phytoplankton for HAB species. These data are publicly available in near real-time to inform shellfish harvesters in Alaska about potential toxin risk.
The SEATOR network can help on a larger scale, as shellfish poisoning is a worldwide problem. Matthew Gribble, Ph.D., assistant professor in environmental health at Emory University, and academic partners at the University of Alaska and the National Oceanic and Atmospheric Administration connected with the STA-ERL and SEATOR network to study the seasonal dynamics of HABs and species-specific toxins. The group recently published a paper that highlights SEATOR data about toxin concentrations and phytoplankton observations.
“Shellfish toxicity is a global problem, and disproportionately affects some coastal communities,” said Gribble. “We want to build models that predict toxicity. Such tools would help coastal communities maintain their traditional food gathering practices and simultaneously protect human health.”
Understanding environmental drivers of HABs, such as sea surface temperature and salinity, will help researchers build predictive models. Marine weather stations in southeast Alaska are relatively far apart and don’t pick up on localized effects, such as freshwater input or tidal flux. Additionally, Alaska doesn’t have a regular state-sponsored monitoring program for shellfish toxins. SEATOR’s data are perfect to fill this gap and provide localized data that can be used to create more accurate models.
“STA-ERL and SEATOR’s work is invaluable for shellfish harvesters in southeast Alaska. They’ve been collecting really useful, really localized data for about five years, and we thought there was a great opportunity to expand the reach of the data,” said Gribble. “Looking at trends in sea surface temperature, salinity, and species-specific toxin levels will help us build models and develop operational forecasts for HABs and shellfish toxins.”
Gribble and his team are also looking more closely at species-specific toxin levels throughout the year. This level of data analysis will help shellfish harvesters practice safe food collection. Additionally, the rigorous analysis will clarify which settings around the world are most like southeast Alaska, thereby expanding the global reach of any models built from SEATOR data.
This collaborative research project, Prevention of Paralytic Shellfish Poisoning in Subsistence Shellfish Harvest Communities of Southeast Alaska, is part of the NIEHS Research to Action program. It goes beyond shellfish toxin analysis by focusing on community concerns and working with existing tribal programs to address those issues. The project’s K-12 educational interventions target shellfish toxicity prevention messages to youth while promoting science education and traditional ways of life. There are also employment and skills-training opportunities for community members.
More About SEATOR
Since 2013, the Sitka Tribe of Alaska has partnered with other tribal organizations to gather data on shellfish toxins. SEATOR’s primary motivation is food security and improving tribal and rural access to traditional foods. To achieve this goal, SEATOR monitors toxic phytoplankton and ocean chemistry, tests shellfish for toxins, works with the Environmental Protection Agency on water quality standards, and tests heavy metal levels in traditional foods.
The SEATOR network is composed of 17 partner tribes throughout the Gulf of Alaska. These partners upload seawater data in near real-time to SEATOR’s website and send shellfish samples for toxin analysis. Shellfish samples are analyzed at the STA-ERL, and data are generally available on the SEATOR website within 48 hours of sample collection. The Sitka Tribe of Alaska built the lab to give subsistence shellfish harvesters in the area a way to test shellfish in near real-time.
Healthy People 2030 Initiative Includes Important National Environmental Health Priorities
The Office of Disease Prevention and Health Promotion recently released Healthy People 2030, which is the fifth iteration of the Healthy People initiative. Healthy People sets national objectives to address the most critical public health priorities. The new initiative includes 12 environmental health objectives that focus on reducing people’s exposure to harmful pollutants in air, water, soil, food, and in homes and workplaces. The environmental health objectives are organized into three categories – general, neighborhood and built environment, and transportation. There are also additional objectives related to neighborhoods and built environment and social and community context. The new custom list tool allows users to build a list of Healthy People 2030 objectives and track them over the next decade.
Improving How Environmental Health Data Are Reported
A recent National Academies of Sciences, Engineering, and Medicine report recommends that research participants be told the results of environmental exposure tests conducted in their communities. Called “reporting back,” this communication helps foster engagement, collaboration, and transparency between researchers and participants. However, there are barriers to reporting back, such as a lack of financial support and established approaches.
To identify pertinent issues and action areas in reporting back environmental health research results, the Community Engagement Core from Emory University’s HERCULES Exposome Research Center hosted a pre-conference workshop at the 2018 PEPH Annual Meeting. Workshop organizers and participants collaboratively identified and organized themes and then created recommendations. Their recent paper, Identifying Issues and Priorities in Reporting Back Environmental Health Data, provides workshop details.
Binational Efforts to Address Cyanobacterial Harmful Algal Blooms in the Great Lakes
Cyanobacterial harmful algal blooms (cyanoHABs) are a recurring problem for the Great Lakes and other freshwater systems. Throughout the 1900s, runoff into the lakes increased the proportions of harmful and noxious cyanobacteria in phytoplankton populations. A 1972 agreement between the U.S. and Canada addressed point sources of runoff, but nonpoint sources related to agricultural activity have increased recently. This activity, paired with global climate change, have increased the frequency and severity of cyanoHABs. As the Great Lakes lie between two countries, successful mitigation of cyanoHABs requires binational coordination. George Bullerjahn, Ph.D., a grantee with the NIEHS Oceans and Human Health program, recently co-authored a book chapter, Binational Efforts Addressing Cyanobacterial Harmful Algal Blooms in the Great Lakes, that explores these issues.
Building a Culture of Health During COVID-19
The Robert Wood Johnson Foundation’s Culture of Health Prize recognizes communities working together at the forefront of advancing health, opportunity, and equity for all. Prizes have gone to communities that transformed education, jobs, transportation and housing. Winning communities stand out for cooperative work that reaches beyond what any one organization could do. Recently, the acting director of the prize blogged about how prize-winning communities are responding to COVID-19. Overall, they are relying on their robust partnerships to meet their residents’ needs. For example, during the height of the pandemic in the spring, the city of Chelsea, Massachusetts organized to set up pop-up food pantries and community partners launched a fund to provide financial relief to meet people’s basic needs.
The Environmental Protection Agency Releases New Lead Exposure Curriculum With Tribal Partners
The Environmental Protection Agency (EPA) recently released a new curriculum, Lead Awareness in Indian Country: Keeping our Children Healthy! The curriculum is meant to:
- Describe actions to reduce or prevent childhood lead exposure.
- Describe lead’s potential impact on children’s health and cultural practices.
- Raise awareness about childhood lead exposure in tribal communities.
The materials were developed with over 200 tribal partners and are designed to be taught by community leaders, even if they are not experts on lead exposure. The curriculum is divided into four main modules and cover topics such as understanding lead and effective cleaning techniques. Each module includes presentation slides and a child’s activity sheet. The EPA is running a series of presentations and trainings to teach community leaders how to use the materials and to discuss how the curriculum is being used.
Harmful algal blooms are overgrowths of toxin-producing algae in natural bodies of water. These toxins can cause serious harm to people, fish, and other parts of the ecosystem, and they can accumulate in shellfish. In our podcast, Harmful Algal Blooms and Your Health, hear more about the adverse impacts of toxins from harmful algal blooms on human health, ecosystems, and the economy. In addition, learn how scientists are exploring the use of toxins and other chemicals released by these algae to treat certain diseases.
