Pantry

Several years

Store in an airtight container in a cool, dry, dark place to prevent moisture absorption and pest infestation. While safe for several years, quality (texture, flavor) may diminish over time.

Refrigerator

Not Recommended

Not recommended

Refrigeration is not necessary and can introduce moisture, leading to staleness or mold. Keep dry.

Freezer

Not Recommended

Not recommended

Freezing is not necessary and can introduce moisture, leading to texture degradation or freezer burn. Keep dry.

Signs of Spoilage

  • Presence of mold (any color)
  • Rancid or off-odor
  • Soft or soggy texture (due to moisture absorption)
  • Signs of insect infestation (e.g., holes, larvae, insects)
  • Significant discoloration

Room Temperature Safety

The 2-hour rule (food should not be left out at room temperature for more than 2 hours, or 1 hour if the temperature is above 90°F/32°C) primarily applies to perishable foods. For dry, shelf-stable items like ship's biscuit, the concern is less about rapid bacterial growth and more about moisture absorption and pests.

The 'Danger Zone' for bacterial growth is between 40°F (4°C) and 140°F (60°C).

Ship's biscuits are shelf-stable at room temperature. The primary concern is keeping them dry and protected from pests. Store in a cool, dry place.
