Hardtack is designed for long-term dry storage. Ensure it remains dry and protected from environmental moisture and pests. If it becomes wet, treat it as a perishable item and discard if left in the danger zone for too long.
Safe Handling
Keep hardtack completely dry to prevent mold and spoilage.
Inspect for signs of moisture, mold, or pest activity before consumption.
Store away from strong odors, as hardtack can absorb them.
