Revised Mollusk Handling Memo
ARCHIVAL NOTICE: This document is part of the Cultural Archives collection. It represents internal communications and operational records from the Concern's divisions. Content is provided for transparency and historical reference.
Background
Following investigation into the Eastern Seaboard Clam Incident of February 2026, the Shellfish Risk Management Division has revised handling protocols for all bivalve mollusks. These changes take effect immediately. There will not be a grace period. This is not a situation that benefits from a grace period.
What Happened
On February 8, 2026, a batch of hard-shell clams from a certified supplier tested positive for elevated biotoxin levels despite passing initial screening. Root cause analysis identified a gap in our temperature monitoring procedures during the 12-to-24-hour post-harvest window — the precise window during which, it turns out, a great deal can go wrong with a clam.
The Shellfish Risk Management Division reviewed the gap. The gap was unacceptable. The gap has been addressed. The Division has also had several internal discussions about the phrase "certified supplier" that this document does not have space to summarize.
Revised Protocol Requirements
Temperature Monitoring
- All mollusk shipments must include continuous temperature logging from point of harvest. Not from point of pickup. From harvest.
- Maximum allowable temperature during transport: 38°F (3.3°C)
- Any temperature excursion above 42°F for more than 30 minutes triggers automatic quarantine. The clams do not get a hearing.
Documentation
- Harvest tags must now include batch-specific GPS coordinates. This requirement was controversial during the review process. It is now required.
- Water temperature at harvest must be recorded and submitted with the shipment
- Chain of custody forms require two additional verification signatures from personnel who have completed the revised mollusk handling training
Testing Protocols
- Random sampling frequency increased from 5% to 15% of incoming shipments. This is a significant increase. The February incident explains why it is necessary.
- Biotoxin screening turnaround time reduced to 4 hours maximum
- All results must be logged in the central database within 24 hours of receipt
Training Requirements
All personnel handling mollusks must complete revised safety training by April 1, 2026. Online modules are available through the Concern's training portal under the category "Bivalve Operations — Mandatory." The training takes approximately 90 minutes. Facilities that fail to meet the compliance deadline will have their mollusk procurement privileges suspended pending full certification.
