Edible fish offal; fish fins, heads, tails, maws and other edible fish offal

1. Scope and Applicability

This PCR applies to foreground production of edible fish offal and edible anatomical parts such as fins, heads, tails, maws (swim bladders), and other declared fish offal prepared for human consumption. It covers separation or receipt of the edible parts, sorting, washing or trimming where performed, preservation or stabilization, packing, and release at the processor gate.

The data package shall identify the fish species or commercial species group, anatomical part, edible status, preservation route, product temperature state, and packaging form. Non-edible offal, fish meal, extracted oils, gelatin or collagen, pet food, feed, pharmaceuticals, whole fish, fillets, and cooked composite dishes are outside this PCR unless they cross the foreground boundary as an explicitly named input, co-product, or waste.

Food-safety controls are mandatory operational constraints but are not substitutes for jurisdiction-specific legal compliance. Numeric safety limits shall be taken from the applicable product, process, and market rules and shall not be inferred from the provisional LCA QA ranges in this candidate PCR.

vr_mass_balance	All mass flows	Verify consistent mass bases, a documented mass balance, and a justified site-specific reconciliation tolerance; a difference outside that tolerance shall produce a finding.
vr_energy_water_waste	Foreground inventory	Verify water, ice, energy, salt or brine, smoking material, packaging, waste, wastewater, and refrigerant rows are present when applicable, with collected values or an explicit justified zero or non-applicability statement.	codex-cxc-52-2003; eu-pef-2021
vr_allocation	Shared and joint operations	Verify allocation choice, driver, co-product set, upstream separation treatment, and sensitivity are disclosed and no burden or credit is double counted.	eu-pef-2021
vr_estimate_disclosure	Provisional data	Verify every use of a provisional range is labelled reasoned_estimate; such ranges are screening flags, not evidence of conformity, and require replacement or uncertainty disclosure.
vr_food_safety_disclosure	Route controls	Verify applicable food-safety control records and market-specific numeric limits are identified; do not validate legal compliance from this PCR's LCA QA ranges.	codex-cxc-52-2003
