Before an algal product reaches any specific end market — food, feed, cosmetics or otherwise — it passes through a set of horizontal EU rules on food safety, hygiene and production standards that apply regardless of the eventual use. This chapter covers that horizontal layer: the General Food Law, the Hygiene Package, HACCP requirements, official controls, and the relevant ISO standards. Readers should treat this chapter as a prerequisite to the Food and Feed chapters, since the rules described here underpin both.

EU food and feed law is built in layers. At the base is a set of general principles and procedural rules that apply to all food and feed business operators, regardless of what they produce. On top of this sit the specific rules for particular product categories (novel foods, additives, supplements, and so on), which are addressed in their own chapters. Separating the horizontal layer from the specific rules avoids repeating the same hygiene and traceability obligations in every downstream chapter, and reflects the way the legislation itself is structured: the General Food Law and the Hygiene Package were designed precisely to provide this common foundation “from farm to fork.”

For algae producers, this horizontal layer matters from the moment biomass is harvested or removed from a cultivation system, regardless of whether the final product will be a food, a feed, a cosmetic ingredient, or something else. Some obligations (such as HACCP) apply differently depending on whether the operator is engaged in primary production or further processing — a distinction explained below that is particularly relevant for algae producers operating their own cultivation-to-processing chain.

Regulation (EC) No 178/2002 of the European Parliament and of the Council of 28 January 2002 laying down the general principles and requirements of food law, establishing the European Food Safety Authority and laying down procedures in matters of food safety, OJ L 31, 1.2.2002, p. 1. EUR-Lex

Relevance to algae: This is the foundational regulation of EU food and feed law. It establishes the general principles that apply to all food and feed business operators — including algae producers and processors — and created the European Food Safety Authority (EFSA). Key provisions:

• Art. 14–15 — Food and feed safety requirements: food or feed that is unsafe must not be placed on the market. This applies to algal biomass and products at every stage.
• Art. 17 — Primary responsibility for food and feed safety rests with the food and feed business operator at each stage of production, processing and distribution, not with the regulator. This means an algae producer is directly responsible for ensuring their product is safe, regardless of whether official inspection has occurred.
• Art. 18 — Traceability: operators must be able to identify who supplied them and to whom they supplied a product (“one step back, one step forward” traceability). For algae producers, this means tracking the cultivation batch, the harvest date, and the downstream buyer.
• Art. 19–20 — Procedures in the event a product is found unsafe: withdrawal and recall obligations.
• Art. 22 — Establishment and tasks of EFSA: the scientific basis for food and feed safety decisions across the EU. See General on EU Legislation for more on EFSA's role.

The General Food Law applies to both food and feed, and is the common reference point cited throughout this wiki whenever “food safety” or “feed safety” obligations are mentioned.

The “Hygiene Package” is the collective name for a set of regulations that entered into force on 1 January 2006, replacing the earlier fragmented hygiene Directives with a harmonised “farm to fork” approach. The package's core elements relevant to algae are:

Regulation (EC) No 852/2004 of the European Parliament and of the Council of 29 April 2004 on the hygiene of foodstuffs, OJ L 139, 30.4.2004, p. 1. EUR-Lex

Relevance to algae: This is the central hygiene regulation applicable to all food businesses, including those producing or processing algae for food use. Key provisions:

• Annex I — Primary production: lays down general hygiene provisions for primary production activities, which includes the cultivation and harvesting of algae before any processing. Requirements at this stage are general and proportionate (clean water, pest control, suitable storage) rather than full HACCP.
• Annex II — General hygiene requirements for all food business operators beyond primary production: covers premises, equipment, water supply, personal hygiene, training, and waste management. These requirements apply once algae are processed (dried, milled, extracted, packaged).
• Art. 5 — HACCP obligation: food business operators must put in place, implement and maintain a procedure based on the Hazard Analysis and Critical Control Point (HACCP) principles. Critically, this obligation does not apply to primary production (Article 5(1) read together with Annex I). For an algae producer, this means: cultivating and harvesting algae as a primary production activity does not legally require a formal HACCP plan, but any further processing — drying, milling, extraction, packaging — brings the operator within the scope of the mandatory HACCP requirement.

This primary-versus-processing distinction is one of the most practically important points in this chapter. An algae farm or photobioreactor facility that only harvests and sells fresh or minimally handled biomass to a third-party processor is treated as a primary producer and subject to lighter requirements. The moment that same operator dries, packages or otherwise transforms the biomass themselves, they become a processor subject to full HACCP obligations.

Regulation (EC) No 853/2004 of the European Parliament and of the Council of 29 April 2004 laying down specific hygiene rules for food of animal origin, OJ L 139, 30.4.2004, p. 55. EUR-Lex

Relevance to algae: Algae are not products of animal origin and this regulation does not directly apply to algal biomass itself. However, it becomes relevant where algae are combined with or processed alongside animal-origin ingredients (for example, in mixed food supplements or compound feed), or where algae are intended for fish or aquaculture feed and the production facility is co-located with animal-origin food handling. It is mentioned here for completeness and because it is frequently cross-referenced in novel food applications and EFSA guidance documents relevant to algae.

Regulation (EC) No 2073/2005 of 15 November 2005 on microbiological criteria for foodstuffs, OJ L 338, 22.12.2005, p. 1. EUR-Lex

Relevance to algae: Sets microbiological safety criteria and process hygiene criteria applicable to foodstuffs, including thresholds for organisms such as Salmonella and Listeria monocytogenes. Although no algae-specific criteria are set, the general criteria for ready-to-eat foods apply to dried or processed algae sold as food. Compliance is verified through sampling and testing as part of an operator's HACCP-based food safety management system.

Regulation (EU) 2023/915 of 25 April 2023 on maximum levels for certain contaminants in food, OJ L 119 5.5.2023, p. 103. EUR-Lex

Relevance to algae: Sets maximum levels for contaminants such as heavy metals, mycotoxins and dioxins in various food categories. This regulation (including the previous version 1881/2006) has been progressively amended to add algae-specific entries, particularly for inorganic arsenic and other heavy metals in seaweed and microalgae-based food supplements. This regulation does not mention any cyanotoxins. Detailed coverage, including the algae-specific limits, is provided in Food Quality and Safety.

Regulation (EEC) No 315/93 of 8 February 1993 laying down Community procedures for contaminants in food, OJ L 37, 13.2.1993, p. 1. EUR-Lex

Relevance to algae: Establishes the general procedural framework under which contaminant limits (such as those in Regulation (EC) No 2023/915) are set, a very short and simple act setting the basic principle that food containing a contaminant at a level unacceptable from the public health viewpoint must not be placed on the market.

Regulation (EU) 2017/625 of the European Parliament and of the Council of 15 March 2017 on official controls and other official activities performed to ensure the application of food and feed law, rules on animal health and welfare, plant health and plant protection products, OJ L 095 7.4.2017, p. 1. EUR-Lex

Relevance to algae: This regulation (which replaced the earlier Regulation (EC) No 882/2004) governs how national competent authorities carry out official controls — inspections, sampling, audits — across the food and feed chain. For algae producers, this is the legal basis under which national food safety authorities will inspect cultivation and processing facilities, take samples for contaminant or microbiological testing, and verify compliance with HACCP and traceability obligations. It also sets requirements for the accreditation of official laboratories, generally requiring conformity with ISO/IEC 17025 for testing laboratories used in official controls. Import controls at EU borders for algae products from third countries are also governed under this regulation; see Customs Classification and Trade.

HACCP (Hazard Analysis Critical Control Points) is an internationally recognised, preventive system designed to ensure food safety by identifying, evaluating, and controlling biological, chemical, and physical hazards. Rather than relying on finished-product testing, it monitors the entire food supply chain from raw material production to distribution and consumption. HACCP is not a formal standard, but it is mandated to be used by the food processors by EU regulation.

The system is built on core principles: conducting a hazard analysis, determining Critical Control Points (CCPs) where safety risks can be prevented, and establishing strict critical limits, monitoring procedures, and corrective actions for each CCP. It concludes with verifying that the system is working effectively and maintaining thorough documentation. It is a self-imposed quality system; CCPs and limits are not prescribed but determined by the process. There is, of course, a body of experience that largely helps certain common types of processes to establish a working system quickly.

There are not many HACCP documents published for algae processes, but a body of knowledge is growing and consulting fellow producers or external consultants may be very helpful in drafting the first versions of the system and its documentation.

ISO 22000:2018 Food safety management systems — Requirements for any organisation in the food chain. ISO

Relevance to algae: ISO 22000 is a voluntary international standard that provides a structured framework for implementing a food safety management system, incorporating HACCP principles together with broader management system requirements (similar in structure to ISO 9001). It is not a legal requirement under EU law, but is widely adopted by (larger) food processors to demonstrate systematic compliance with HACCP obligations and to meet market access requirements for many buyers, particularly in international trade. ISO 22000 is often implemented together with the sector-specific prerequisite programme standards in the ISO/TS 22002 series (for example, ISO/TS 22002-1 for food manufacturing or ISO/TS 22002-3 for farming), which provide more detailed operational guidance suited to a producer's specific stage in the supply chain (none of them is directly applicable to algae production but rather by analogies and adaptations).

The relationship between HACCP and ISO 22000 is often a source of confusion: HACCP (as required by Regulation (EC) No 852/2004, Article 5) is a hazard analysis methodology, whereas ISO 22000 is a comprehensive management system standard that incorporates HACCP as one of its components alongside prerequisite programmes, communication requirements and continuous improvement processes. An operator can be legally compliant with EU hygiene law by implementing a HACCP plan without being ISO 22000 certified; ISO 22000 certification is an additional, voluntary layer that demonstrates a more complete management system, often expected by larger commercial buyers.

• Good Manufacturing Practice (GMP) — a quality assurance approach originating in the pharmaceutical sector, also applied in food and feed manufacturing, focused on consistent production according to quality standards.
• Codex Alimentarius — the joint FAO/WHO international food standards programme. The Codex General Principles of Food Hygiene (CXC 1-1969) describe Good Hygienic Practice (GHP) and HACCP principles and underpin much of the EU hygiene framework and that of many trading partners.
• GLOBALG.A.P. — a private certification scheme covering Good Agricultural Practice, increasingly referenced by buyers, particularly for primary production.
• ISO/IEC 17025 — the international standard for the competence of testing and calibration laboratories. Relevant to algae producers operating in-house testing laboratories, and a requirement for any laboratory whose results are intended to be used in regulatory disputes or official controls (see Regulation (EU) 2017/625 above).

Council Directive 89/391/EEC of 12 June 1989 on the introduction of measures to encourage improvements in the safety and health of workers at work, OJ L 183, 29.6.1989, p. 1. EUR-Lex

Relevance to algae: This is the framework Directive for occupational health and safety across the EU. Its transpositions to national legislation are quite different so local rules should be consulted. Algae producers, as employers, must train staff to use cultivation and processing equipment correctly and provide a safe working environment. This is particularly relevant for facilities that use pressurised systems, centrifuges, spray driers, or chemical extraction processes. There are also relevant limitations regarding work in greenhouses or under high-temperature and high-humidity conditions. Equipment-specific safety legislation is covered in Equipment and Safety.

Beyond regulatory compliance, algae producers commonly provide commercial documentation that, while not required by EU law, is standard market practice and often a condition of sale:

• Technical Data Sheets (TDS) — describing the composition, specifications and intended use of a product.
• Certificates of Analysis (CoA) — batch-specific test results confirming compliance with agreed specifications (e.g. contaminant levels, microbiological counts, nutrient content).
• Safety Data Sheets (SDS) — required for substances and mixtures under REACH and CLP where applicable, though most food-grade algal biomass itself does not require an SDS unless classified as hazardous.

It is useful to distinguish certification (voluntary third-party attestation against a standard, such as ISO 22000 or organic certification) from regulatory compliance (mandatory, verified by official competent authorities, with direct legal consequences for non-compliance). Both matter commercially, but only the latter is a legal requirement.
