2. 1. DEFINITIONS.
2.1.1. Aquaculture: The activity of cultivating aquatic organisms, including fish, mollusks, and crustaceans.
2.1.2. Additive: Any substance that is not normally consumed as food in itself, nor used as a basic ingredient in food, whether or not it has nutritive value, and whose intentional addition to food for technological purposes (including organoleptic purposes) in its phases of production, processing, preparation, treatment, packaging, packing, transport, or storage, results or may reasonably be expected to result, directly or indirectly, by itself or its by-products, in it becoming a component of the food or an element affecting its characteristics. This definition does not include "contaminants" or substances added to food to maintain or improve nutritional qualities.
2.1.3. Potable water: Water that complies with the provisions for recommended values or maximum permissible levels for aesthetic, organoleptic, physical, chemical, biological, and microbiological parameters contained in Executive Decree Nº 32327-S of February 10, 2005, "Regulation for the Quality of Potable Water".
2.1.4. Competent authority: The National Animal Health Service (SENASA) of the Ministry of Agriculture and Livestock, established by Law Nº 8495 of April 6, 2006.
2.1.5. Contaminant: Any chemical, microbiological, or biological agent, or other substance not intentionally added to food, which may compromise its safety or the suitability of the food.

Veterinary drug: Any natural, synthetic, or semi-synthetic substance or product, and any mixture of those substances or products, used for the diagnosis, prevention, treatment, and relief of diseases or abnormal physical states, or their symptoms, and for the restoration or modification of organic functions in animals; cosmetics are included. This definition includes all additives with pharmacological properties, such as coccidiostats, antibiotics, and growth promoters, used in animal feed, as well as pesticides and cosmetic-type products for veterinary use, and medicated feeds marketed at therapeutic concentrations.
2.1.15. Mollusks: Soft-bodied invertebrate animals, naked or protected by a shell; such as snails, oysters, and slugs.
2.1.16. Fresh fish: Refers to fish or fish-based preparations that, in their final form, have not undergone any preservation treatment other than refrigeration.
