Fish, Otherwise Prepared or Preserved

1. Scope and Applicability

This PCR covers fish products that are prepared or preserved by routes not represented by a more specific fish-product PCR. The representative product is frozen surimi: stabilized, washed and dewatered minced fish protein intended for later food manufacture. The foreground boundary covers the receiving and storage of fish and ingredients, fish preparation and meat separation, repeated washing and dewatering, refining, final dewatering, mixing with declared adjuvant ingredients, packaging, freezing, metal detection, frozen storage, and preparation for dispatch.

The PCR also applies to another otherwise-prepared or preserved fish product only when the foreground data package replaces the representative route with the actual preparation or preservation steps and declares product form, species, formulation, preservation method, thermal treatment, storage state, and packaging. It excludes caviar and caviar substitutes, fish fillets or minced fish sold without the surimi washing/stabilization route, prepared crustaceans or molluscs, and downstream surimi-based foods such as formed seafood analogues. Fishing or aquaculture, production of purchased ingredients and packaging, distribution after the factory gate, retail, cooking, consumption, and end-of-life are outside the foreground boundary and require linked upstream or downstream datasets when included in the study.
