meat
the flesh of animals (including fishes and birds and snails) used as food
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.
Researched by: Codex + Grok
Purpose and description
Enable an agent to identify animal flesh used as food, assess its documented condition and suitability, and determine appropriate handling or processing actions.
Edible skeletal and other muscle tissue of animals (including fishes, birds, and molluscs such as snails), together with attached fat, connective tissue, and permitted offal, used as food.
It can be Identify and compare meat portions by species, tissue, form and documented composition.; Trace a portion to source lots and identify related material after splitting or mixing.; Assess whether storage and processing records support a proposed use.; Select applicable handling or processing instructions using species, form, state and intended use.; Flag uncertain identity, missing history or adverse findings for segregation and review.; Record changes after cutting, mincing, thawing, cooking or preservation and reassess suitability..
Distinguishing features
The material is animal flesh used as food; animal origin alone does not make milk, eggs or isolated protein meat.
Fish, bird and snail flesh qualify under this registry definition even where culinary or regulatory vocabularies classify them separately.
The referent is a portion or lot of food material, rather than the animal from which it originated.
A composite product containing meat must distinguish its meat component from added water, binders, coatings and other ingredients.
Species, anatomical part and processing state distinguish meat instances without requiring a single chemical formula or universal purity grade.
Scope
+ Species and anatomical origin of flesh intended or presented for human consumption
+ Physical form, tissue composition and measurable properties of a meat portion or lot
+ Raw, cooked, preserved, chilled, frozen and thawed states and their histories
+ Evidence relevant to spoilage, contamination, suitability and handling decisions
+ Lot provenance, traceability and applicable use restrictions
- Living animals, husbandry systems and animal health records except as linked provenance
- Plant-based substitutes and products that imitate meat without containing animal flesh
- Milk, eggs and isolated animal-derived chemicals such as purified collagen
- Whole meals and composite food products beyond their identifiable meat component
- Slaughterhouses, processing equipment and supply-chain organisations as entities
- General dietary advice and individual clinical nutrition decisions
Characteristics
- Source animal identity
- Declared or verified taxon; multiple taxa or unknown; linked identification evidence Supports recognition, authenticity checks and species-dependent handling or use constraints.
- Anatomical and tissue identity
- Named cut or body part; muscle, associated fat, connective tissue, mixed tissue or unresolved Distinguishes portions with different composition, preparation behaviour and boundary questions.
- Physical form
- Intact cut, sliced, chopped, minced, mechanically separated or other documented form; bone and skin status Identifies how the material has been divided or altered and which handling evidence is relevant.
- Composition
- Water, protein, fat and other specified constituents in g/100 g; analytical method and raw/cooked basis Supports comparison and processing decisions without treating variable biological material as a pure substance.
- Temperature
- Degrees Celsius; core or surface location, timestamp and measurement method Provides a time-specific observation for evaluating storage and processing history.
- Processing and preservation state
- Documented combination of raw, cooked, chilled, frozen, thawed, cured, dried, smoked or other treatment Determines which subsequent actions require evidence and prevents a treatment label from implying safety.
- Acidity and water availability
- pH and water activity, dimensionless; method, sampling location and timestamp Provides product-specific evidence when assessing preservation and stability.
- Condition observations
- Recorded colour, odour, texture, exudate and visible deterioration; acceptable, suspect or unassessed against named criteria Supports condition assessment while keeping sensory observations separate from safety clearance.
- Hazard assessment
- Hazard-specific result, method, sampling basis, applicable criterion and assessment date; unknown where untested Makes the evidence and limits behind a suitability decision explicit.
- Lot and custody identity
- Supplier lot, parent and child lots, processing events and custody records Maintains traceability through cutting, mixing, repacking and distribution.

Drafted structure
Bundle to layer to finding to question, as the second pass will find it: 6 bundles · 11 layers · 18 findings · 28 questions.
Animal flesh identity Establish what animal material is present and how it fits this registry sense of meat.
Meat identity depends on biological and anatomical origin, while common names can obscure species and scope.
Species and food sense
Identify the source animal and the material's use as food.
Source taxon and food intent
Record declared identity, supporting evidence and whether the flesh is intended or presented as food.
- Which animal taxon or mixture of taxa supplied this flesh, and what evidence supports that identification? provenance
- Does the record refer to animal flesh used as food under vr.tr.meat, including fish, bird or snail flesh? definition
Anatomical boundaries
Locate the portion within the animal and distinguish included tissue from neighbouring materials.
Cut and tissue membership
Describe the anatomical part and clarify the treatment of associated tissues and non-flesh components.
- Which cut, body region or organ does the portion represent, and which tissues are included? definition
- Are bone, shell, skin, separate fat or viscera included in the recorded mass, and which require an explicit scope decision? boundary
Flesh composition and form Describe the variable material composition and physical organisation of the meat.
Cuts, mixtures and comminuted flesh cannot be represented adequately by a chemical identity or generic purity value.
Tissue and ingredient composition
Separate native tissue composition from substances added during preparation.
Composition on a stated basis
Record measured or declared constituents with their measurement basis and distinguish added ingredients.
- What water, fat and protein values are available, and do they describe the raw, cooked or otherwise processed material? measurement
- Has water, salt, curing material or another ingredient been added, and is the referent still the meat component or a composite product? boundary
Portion geometry and disruption
Describe size and physical interventions affecting the flesh.
Intactness and portion size
Record portion dimensions and whether tissue has been minced, injected, tenderised or otherwise disrupted.
- What are the portion mass and relevant dimensions, or the particle-size description for minced material? measurement
- Which cutting, mincing, injection, mechanical separation or tenderising operations have been applied? provenance
Post-harvest state history Track time, temperature and treatments from slaughter or harvest to the present state.
A current label such as chilled or cooked cannot substitute for the history needed to assess meat.
Thermal and storage history
Capture storage intervals, freezing and thawing events, and gaps in temperature evidence.
Time-temperature record
Associate thermal observations with the lot and identify unsupported intervals.
- What slaughter or harvest, chilling, freezing and thawing times are known for this lot? provenance
- Which core or surface temperatures were measured during storage and transfer, and where are the record gaps? measurement
Preservation and maturation
Represent cooking, curing, drying, smoking and ageing as documented treatments.
Treatment parameters and outcomes
Distinguish a named process from evidence that its intended outcome was achieved.
- Which cooking, curing, drying, smoking or ageing treatments occurred, with what recorded parameters? provenance
- What measurements or validation records support the claimed treatment outcome for this meat? measurement
Condition and food suitability Assess observed deterioration and hazard evidence against the proposed use.
Meat condition, safety evidence and intended preparation must remain distinguishable in agent decisions.
Sensory and material condition
Record observations of the flesh and its immediate storage environment.
Condition observations and limits
Capture visible and sensory changes without treating their absence as proof of safety.
- What changes in colour, odour, texture, exudate or surface appearance were observed, and when? measurement
- Do those observations warrant segregation or further assessment under the applicable product criteria? action
Hazards and use criteria
Connect relevant biological, chemical and physical hazard evidence to a specific intended use.
Evidence-bounded suitability
Make suitability conditional on applicable criteria, sampling limitations and preparation assumptions.
- Which hazard assessments apply to this species, tissue, processing state and intended use, and what results are available? measurement
- Does the evidence support the proposed use, require further processing or assessment, or require withholding the lot? action
Meat lot lineage and disposition Maintain provenance and determine which documented actions remain available for a portion or lot.
Cutting and mixing change lot relationships, while identity and use restrictions must follow the resulting meat.
Source and transformation lineage
Connect meat to source records and subsequent division or combination events.
Parent and child meat lots
Preserve traceability through butchery, mincing, blending and repacking.
- Which supplier, slaughter or harvest records and parent lots establish the origin of this portion? provenance
- Which child lots received material from it, and which other meat lots were mixed into it? provenance
Claims, restrictions and next actions
Relate verified claims and applicable restrictions to proposed handling or release.
Documented use constraints
Record the authority and scope of claims or restrictions without inferring them from appearance or species alone.
- Which jurisdictional category, certification, supplier instruction or lot restriction applies, and what document supports it? provenance
- What evidence is required before this lot may be released, thawed, cooked, repacked or otherwise redirected? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
A model that cannot be lined up against existing standards, identifiers and practice cannot be adopted by anyone who already uses them.

- US retail and USDA 'meat' historically centres on livestock (cattle, swine, sheep, goats); poultry is inspected under a separate statute
- Halal and kosher rules restrict species (no pork; kosher also excludes shellfish and requires shechita) and blood removal
- Naming of cuts differs sharply (US vs UK vs French primal/retail cut maps; 'mince' vs 'ground beef')

Neighbouring kinds and how to tell them apart
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- meat (other registry sense) - This model is the foodstuff (animal flesh used as food). The duplicate batch name is a different sense and must not be merged; test is whether the referent is edible tissue of an animal.
- muscle / skeletal muscle (anatomical tissue) - Anatomy describes living or dissected tissue regardless of food use; meat is that tissue after slaughter (or harvest) when it is a food commodity, usually including fat and connective tissue.
- carcass - The dressed body after slaughter; meat is the edible tissue derived from it (and from offal). A carcass is a unit of trade and inspection, not a culinary cut.
- protein (nutrient) - Protein is a macronutrient class present in meat, dairy, legumes and many other foods; meat is the animal-tissue food, not the molecule.
- meat analogue / plant-based 'meat' - Formulated from plants, fungi or fermentation to mimic meat; contains no slaughtered-animal muscle. Label and legal identity are non-meat in most jurisdictions.
- offal vs skeletal meat - Offal is viscera and other non-skeletal edible parts; many legal definitions include it in 'meat' but retail and nutrition often list it separately.
- fish as 'seafood' rather than 'meat' - Culinary and EU hygiene law treat fishery products as a separate category; the sense researched here includes fish flesh as meat in the broad English/food-anthropology sense.
- Which of these neighbouring kinds and how to tell them apart hold for the sense of meat this model covers, and on what evidence? provenance

What the second pass must settle
- How does the other registry entry named meat differ from vr.tr.meat, and does an existing world model already cover this exact sense?
- Where does this registry draw the boundary for edible organs, blood, separately rendered fat, skin and other animal tissues?
- How should cultivated animal tissue be classified relative to the definition of animal flesh used as food?
- At what point do added ingredients or structural transformation make the whole referent a composite food product with a linked meat component?
- Which authoritative sources establish species-, form-, process- and jurisdiction-specific criteria for hazards, storage, shelf life and permitted use?
