1. RECEIVING
Direct Vessel - live oysters are purchased from local fishing vessels that harvest the shellstock by hand (tongs) from approved and/or conditionally approved waters of Apalachicola Bay. Harvest will be subject to the surveillance of an assigned Harvest Surveyor. Shellstock is off-loaded at the plant's dock or at the satellite landing locations, where the product is inspected for survival, legal size, and general condition (mud, clusters, singles, and appearance), and monitored for legal harvester's tags. Each lot is assigned a dealer's lot number.
Local Trucks (shellstock) - live oysters are delivered by truck to the processing plant, less than 4 hours from the landing site. Product is off-loaded, inspected for temperature and general condition, monitored for legal harvester's tags, re-tagged, and assigned a dealer's lot number.
Local Trucks (previously shucked meats) - shucked meats are delivered in refrigerated trucks or properly iced in non-refrigerated trucks. Product is off-loaded at the processing plant, less than 4 hours from the original shucking plant, and inspected for lot number, internal temperature and general condition. Only product from approved shucking plants are purchased.
Distant Trucks (shellstock and previously shucked meats ) - product transported for greater than four hours must be delivered to the processing plant in refrigerated trucks. Refrigeration is monitored by a time-temperature device. Shellstock is checked for temperature, tag, conditioned and then re-tagged and assigned a lot number.. Previously shucked meats are checked for internal temperature, original shucker certification number and product condition.

Dry storage 2. PRODUCT COLD STORAGE
Within 2 hours after receipt, shellstock is placed into walk-in coolers set for an operating temperature low enough to achieve a product internal temperature no higher than 45°F (7.2°C). Shucked meats are placed in refrigerators that will maintain an internal temperature no higher than 40°F (4.4°C). Temperatures of coolers and refrigerators are monitored by a time-temperature chart recorders.

3. PROCESSING
Washing - Shellstock are rinsed with high pressure water hose to remove dirt from surface.
Grade/Cull - Shellstock are washed, graded and culled to select only product that meets the requirements of clustering or size for half shell commerce. Product that does not meet the required standards is taken to the shucking room with proper lot identification.
Box - Shellstock is re-tagged, bagged or boxed and sent to final storage.
Hand Shucking - Live shellstock are taken into the shucking room and distributed between workers by a conveyor belt or bulk delivery. Oysters are shucked into a 1-2 gallon stainless steel container with ice-water. When the container is filled, it is taken to the packing room for further processing.
Cleansing (Blowing) - Shucked meats are inspected and placed into a stainless steel vat with ice-water. Filtered air is blown through the ice water and oyster mixture. Cleaned product is unloaded to the skimming table to be graded and packed.
Skimming and Grading - Product is rinsed, drained and visually graded for size.
Packing - Oyster meats are packed into the final containers which are marked with the correct lot number for each corresponding batch.

Finished Product Cold Storage 4. FINISHED PRODUCT COLD STORAGE
Fresh Products - Shellstock is placed inside coolers at a temperature of 45°F (7.2°C) or lower. Shucked products are kept at a maximum temperature of 40°F (4.4°C). Temperatures of coolers and refrigerators are monitored with a time-temperature recorders.
Frozen Products - Product is packed into 4 lb. Pillow bags or suitable containers, frozen as rapidly as possible, and kept frozen (0°F, -17.8°C) until needed. Product should be frozen solid within 12 hours of starting the freezing process.
