-Cyanobacteria — commercially the most important group being //Limnospira// (Spirulina), //Aphanizomenon// and others — are capable of producing a range of toxins collectively known as cyanotoxins. These include __microcystins__ (hepatotoxic, produced by various genera including //Microcystis// and, under certain conditions, contaminating cyanobacteria co-occurring with cultivated species), __anatoxins__ (neurotoxic), and __cylindrospermopsin__ (cytotoxic). This is a hazard with __no close analogue__ in conventional terrestrial food crops, and is the most distinctive food safety issue specific to algae as a food category.+Cyanobacteria — commercially the most important group being //Limnospira// (Spirulina), //Aphanizomenon// and others — are capable of producing a range of toxins collectively known as cyanotoxins.

   * __Misidentification or mislabelling__, where a product sold as a edible cyanobacterium (e.g. Spirulina/Limnospira) is in fact contaminated with or substituted by a different, toxin-producing species — a known issue with some wild-harvested or poorly controlled supply chains, particularly for products sourced outside the EU.   * __Misidentification or mislabelling__, where a product sold as a edible cyanobacterium (e.g. Spirulina/Limnospira) is in fact contaminated with or substituted by a different, toxin-producing species — a known issue with some wild-harvested or poorly controlled supply chains, particularly for products sourced outside the EU.
  
-There is currently __no harmonised EU maximum level__ specifically for cyanotoxins in food, although EFSA has published scientific opinions assessing the risk and the German Federal Institute for Risk Assessment (BfR) and French food safety agency (ANSES) have both issued guidance recommending maximum microcystin levels in Spirulina-based food supplements (commonly cited informal benchmarks are in the range of 1 µg microcystin-LR equivalent per gram of dry product, though this is not a binding EU-wide limit). Producers and buyers commonly test for microcystins as part of batch quality control even in the absence of a binding EU limit, and several national authorities have taken enforcement action against products found to contain elevated cyanotoxin levels. This is an area of EU law still under active development; see [[algae:cases_precedents|Regulatory Cases and Precedents]] for documented cases.+There is currently __no harmonised EU maximum level__ specifically for cyanotoxins in food, although EFSA has published scientific opinions assessing the risk and defining the tolerable daily intakes (TDI) for many of them in a comprehensive scientific report commissioned by EFSA delivered in 2016 [[https://anses.hal.science/anses-01348179/document|Testai et al, 2016]]. Based on this report German Federal Institute for Risk Assessment (BfR) and French food safety agency (ANSES) have both issued guidance recommending maximum microcystin levels in Spirulina-based food supplements (commonly cited informal benchmarks are in the range of 1 µg microcystin-LR equivalent per gram of dry product, though this is not a binding EU-wide limit).

 __Relevance to algae:__ This is a __Recommendation__, not a binding Regulation (see [[algae:eu_legislation_general|General on EU Legislation]] for the distinction), but it is highly relevant in practice. It recommends that member states monitor levels of arsenic, cadmium, iodine, lead and mercury in seaweed, halophytes and seaweed-based products over a three-year period, with the explicit purpose of building the evidence base for future binding maximum levels. Producers should expect that the data gathered under this Recommendation will inform future amendments to Regulation (EC) No 2023/915, and that current voluntary monitoring practice is a strong indicator of where binding limits are likely to be introduced next. __Relevance to algae:__ This is a __Recommendation__, not a binding Regulation (see [[algae:eu_legislation_general|General on EU Legislation]] for the distinction), but it is highly relevant in practice.

-__Relevance to algae:__Among other drinking water +__Relevance to algae:__ High-quality, safe and sufficient drinking water is essential for public health and well-being. Besides consumption, it is also used for many other purposes, such as washing, cleaning, hygiene, or watering our plants, and frequently also algae cultivation. The directive defines access to high-quality drinking water. Main objective is to ensure that water intended for human consumption can be consumed safely. 
 + 
 +The Drinking Water Directive seems to be the only place in EU regulation that mentions cyanotoxins (specifically microcystin-LR) and defines the allowed concentration. Although not directly applicable, this limit may also be used "mutatis mutandis" as an intake limit for algal biomass.
