We will explain how to know if a preserve is in poor condition. These small tips will help you know if a can has gone bad, even without opening:

• Never consume the contents of a bulging can or that releases a lot of air or liquid under pressure when opening.

• Avoid cans with perforations, leaks or rusted.

• Distinguish between preserves and semi-preserves, and keep the latter in the fridge.

• Finally, avoid any suspicious food which smell or taste seems unusual.

Despite these points, the quality controls undergone by all preserves usually avoid any manufacturing defect.

However, due to accidents in the handling, transport or storage, some preserves might not meet all the ideal conditions to be consumed.
