| Energy and Protein Bars | |

Storage tips
- Coast-Guard-approved ration bars are made for heat and long storage; regular snack bars are not.
Signs it has gone bad
- A stale, bitter or rancid taste, usually from nuts and seeds
- Mold, especially on dried fruit and soft bars
- A white or grey film on chocolate is fat or sugar bloom, which is harmless
- A torn wrapper or packaging that lets in moisture or pests
