How to tell jams, jellies, and preserves have gone bad

General signs for condiments, sauces & canned goods, the group USDA lists jams, jellies, and preserves under.

• Dented, bulging or rusted cans, especially at the seams
• Hissing sound or spray when a can or jar is opened
• Mould on the surface of a sauce or condiment
• Separation, discoloration or a sharp off smell from the jar
• Metallic taste or cloudy liquid in canned food

Storage habits that make the difference

Refrigerate opened condiments and sauces with their lids on tightly, and use a clean spoon each time to avoid contamination. Store unopened cans in a cool, dry cupboard, and once opened, transfer leftover canned food to a covered container in the fridge rather than storing it in the can.
