Marine phycotoxins from microalgae threaten ecosystems and human health. This review highlights the need for better toxicity data and detection methods to ensure food safety and address climate change impacts.
Area of Science:
- Marine Biology
- Ecotoxicology
- Food Safety
Background:
- Marine phycotoxins are bioactive compounds from microalgae that enter the food web.
- These toxins pose risks to ecosystems, human health, aquaculture, and tourism.
- Human health and food safety are primary concerns regarding phycotoxin impacts.
Purpose of the Study:
- To review current knowledge on marine phycotoxins.
- To address uncertainties in toxicity data and detection methods.
- To discuss the influence of climate change on phycotoxin prevalence.
Main Methods:
- Literature review of marine phycotoxin research.
- Analysis of current toxicological criteria and detection methodologies.
- Examination of climate change impacts on microalgal blooms.
Main Results:
- Existing toxicity data lacks traceability, necessitating defined toxicological criteria.
- Despite advancements, methodological uncertainties persist in phycotoxin detection.
- Climate change introduces further complexities to phycotoxin monitoring and risk assessment.
Conclusions:
- Standardized toxicological criteria and universal detection methods are crucial for phycotoxin management.
- Addressing methodological uncertainties is vital for accurate risk assessment.
- Future research should integrate climate change projections into phycotoxin studies.
