Lobsters, frozen, dried, salted or in brine

1. Scope and Applicability

This PCR covers foreground production of lobster preserved by one declared route: frozen, dried, salted, or held in brine. A sequential combination is included only when it is the actual declared production route; route-specific inputs and outputs shall not be averaged across products made by different routes. The foreground boundary begins with received live, raw, chilled, or otherwise unpreserved lobster at the processing gate and ends with packaged preserved lobster at the facility gate after on-site storage.

Fishing or aquaculture, production of purchased materials and utilities, distribution, retail, consumer preparation, and packaging end-of-life are outside the foreground boundary and require appropriate upstream or downstream datasets. Food-safety conformity is a prerequisite for data acceptance, not an environmental performance claim.
