Scallops, frozen, smoked, dried, salted or in brine

1. Scope and Applicability

This PCR covers edible scallop products preserved for sale by one declared primary route: frozen, smoked, dried, salted, or held in brine. The five primary route labels are mutually exclusive for a foreground data package. A selected route may include necessary ancillary steps, such as preparatory salting or drying within smoking, but those steps do not create additional primary routes. Mixed products and sequential preservation routes require a separate, explicitly documented study scope.

The foreground boundary starts with an accepted lot of raw scallops at the preservation facility and ends with qualified, packaged product released at the facility gate under its declared storage condition. Aquaculture or wild harvest, landing, and transport to the facility are represented by upstream datasets. Retail, use, and end-of-life are outside the foreground boundary unless the study expands it and discloses the expansion.

The numerical ranges below are deliberately broad, provisional authoring and QA screens with evidence kind reasoned_estimate. They apply only when route- and site-specific foreground records are not yet available, are not conformance limits, and must be replaced when measured batch records or reviewed source-backed ranges become available.
