How to tell retort pouches or boxes have gone bad
General signs for meat: shelf stable foods, the group USDA lists retort pouches or boxes under.
- Bulging, dented or rusted cans, especially along the seam
- Jerky that has gone soft, sticky or visibly mouldy
- Hissing or spurting liquid when a can is opened
- Off, sour or rancid smell on opening
- Unusual colour change compared to a fresh package

Storage habits that make the difference
Store unopened cans and sealed jerky in a cool, dry cupboard away from direct sunlight. Once opened, refrigerate canned meat in a covered container and use within a few days. Reseal jerky tightly or keep it in an airtight bag or container after opening to preserve texture.
