Methodologies for Detoxifying Bivalves from Marine Paralytic Shellfish Toxins

Area of Science:

• Marine Biology
• Environmental Chemistry
• Food Safety

Background:

• Marine environments provide essential food and products but face threats from harmful algal blooms (HAB).
• HABs produce biotoxins, such as paralytic shellfish toxins (PST), which accumulate in seafood, posing risks to human health and seafood quality.
• Paralytic shellfish poisoning (PSP) is a significant concern due to the potency and lethality of PST.

Purpose of the Study:

• To review and analyze existing methods for removing paralytic shellfish toxins (PST) from marine environments.
• To identify knowledge gaps and challenges in current PST removal strategies.
• To provide insights for developing effective, safe, and cost-efficient PST removal technologies.

Main Methods:

• Comprehensive literature review of PST removal techniques.
• Analysis of the efficacy of various methods including thermal, industrial, adsorption, photodegradation, and advanced oxidation processes (AOPs).
• Comparative assessment of PST removal strategies based on efficiency, environmental safety, cost, and availability.

Main Results:

• Existing methods for removing PST from marine environments are largely unproven or ineffective.
• PST removal is challenging due to their hydrophilicity and susceptibility to environmental factors.
• A significant need exists for innovative, rapid, environmentally benign, and economical PST removal solutions.

Conclusions:

• There is a critical need for the development of novel technologies for PST removal.
• Further research is required to overcome the challenges associated with PST hydrophilicity and environmental interactions.
• Effective PST mitigation strategies are essential for safeguarding marine food sources and public health.
