1. Introduction

According to law, certain HACCP functions must be performed by someone who has completed training equivalent to the HACCP Training Curriculum (publication UNC-SG-96-02) developed by The National Seafood HACCP Alliance for Training and Education. These functions include developing the plan, changing the plan, and conducting record review. This training may be obtained through classroom instruction or by equivalent on-the-job training. See Sec. 123.10 of the regulations for details. This generic HACCP plan for Pacific oysters is based on the principles detailed in that manual, in guidance contained in the FDA's Fish and Fisheries Products Hazards and Controls Guide, First Edition, September 1996, and the National Shellfish Sanitation Program Manual of operations, Part II, Sanitation of the Harvesting, Processing, and Distribution of Shellfish, 1995 Revision.

Oyster processors also should be aware that FDA's HACCP regulation (Procedures for the Safe and Sanitary Processing and Importing of Fish and Fishery Products; Final Rule, December 18, 1995) requires that they monitor and keep records on their sanitation procedures. This is best done by writing and implementing an SSOP (Sanitation Standard operating Procedure). Examples of this can be found on University of California's Seafood NIC Web site .

Note #1: Area growing water closures due to run off from agricultural lands are based on rainfall in specific watersheds so some areas may be open while others are closed. Other closures due to municipal sewerage treatment plants or other overflow/spills may be site specific. No harvesting or production from wet storage occurs during closed periods.

Note #1: The SSCA (State Shellfish Control Agency) has an estuary-specific management plan for all harvest areas. The SSCA closes harvest areas for both predictable and non-predictable causes. All certified dealers are notified by telephone of any area closures (24 hrs/day notification) followed by written confirmation. The notification list for predictable closures includes appropriate state, federal, and local agencies and commercial shellfish dealers. The notification list for non-predictable closures adds appropriate news media.

Note #2: Verification includes validation of HACCP plan by review of flow diagram and hazard analysis after any process changes and at least annually.

Definitions: SSCA--State Shellfish , ISSC--Interstate Shellfish Sanitation Conference, NSSP--National Shellfish Sanitation Program, WS--wet storage, DS--Dry Storage.
