Understanding these is essential context before looking at the specific contaminant limits below.+Algae present several food safety hazards that are either unique to algae or considerably more significant for algae than for conventional food crops. Understanding these is essential context before looking at the specific contaminant limits below. A very good survey of Chemical and microbiological contaminants in algae for food is in [[https://maritime-forum.ec.europa.eu/document/download/2b1b0a8f-1bb6-4026-ae5d-5f4df0df06ea_en?filename=Chemical%20and%20microbiological%20Contaminants%20in%20Algae%20for%20Food_20240516_Sm_nd.pdf|a workgroup report in EU4algae project]].

 +Regulation (EC) No 1881/2006 of 19 December 2006 on the same topic, OJ L 364, 20.12.2006, p. 5. [[https://eur-lex.europa.eu/legal-content/EN/AUTO/?uri=CELEX:02006R1881-20230326&qid=1781829956180|EUR-Lex]]. This regulation changes frequently (on average, more than twice a year).

Key points:
  
   * __Inorganic arsenic__: maximum levels have been introduced for inorganic arsenic in certain seaweed-based foods and food supplements, reflecting the toxicological distinction between organic and inorganic arsenic species described above.   * __Inorganic arsenic__: maximum levels have been introduced for inorganic arsenic in certain seaweed-based foods and food supplements, reflecting the toxicological distinction between organic and inorganic arsenic species described above.

 +  * __Mycotoxins__: are regulated; they are not directly produced by algae, but might be produced during storage.
   * The regulation is amended frequently as new data become available; producers should always check the current consolidated version rather than relying on a fixed list, as new algae-specific entries continue to be added.   * The regulation is amended frequently as new data become available; producers should always check the current consolidated version rather than relying on a fixed list, as new algae-specific entries continue to be added.

Cyanotoxins are regulated by the Drinking water directive (below) and Dynoflagellate biotoxins primarily occur in shellfish and are regulated by EU Regulation 853/2004 and 786/2013 (below). Limits for cyanotoxin and Dynoflagelate biotoxin content are also specified by German Federal Institute for Risk Assessment (BfR) and French food safety agency ANSES as well as in comprehensive [[https://www.who.int/publications/i/item/9789241549950|WHO Guidelines for Drinking-Water Quality]]. None of these is directly applicable to algae but each of them can serve as a good guideline.

No algae-specific microbiological criteria currently exist; the general criteria for the relevant food category (e.g. dried herbs and spices, ready-to-eat foods, food supplements) are applied by analogy and by national competent authorities' risk-based judgement. //Listeria monocytogenes// maximum limits introduced for all food categories are particularly relevant for moist or minimally processed algal products. __Relevance to algae:__ Sets process hygiene criteria and food safety criteria for pathogens including //Salmonella// and //Listeria monocytogenes//.

-__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 1881/2006, 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:__ 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.
