Don't eat dried cuttlefish past its shelf life.

The conditions under which food is stored are critical to the quality of the food. Shelf life is usually for the type of food related to the appropriate storage conditions and the development of, such as in the ordinary cookies on the packaging, you can see "storage methods: avoid the sun, stored in a cool, dry place, after opening, please eat as soon as possible" and so on. If the cookies are stored in a severe sun exposure, high temperature, or humid environment, its actual shelf life will be much shorter than the preset shelf life on the packaging.

The integrity of a food's packaging is also an important measure of its quality. Foods with defective packaging are susceptible to moisture or bacterial growth and are relatively less safe. The shelf life of opened food will also be shortened. Food should be consumed as soon as possible after opening to avoid mold and mildew. The chemical stability of preservative additives in food also decreases with time. In other words, the longer the food has been out of the factory, the less quality can be guaranteed.

Extended information:

Food that has passed its shelf life doesn't necessarily mean it can't be consumed any more, it's like a machine that's passed its shelf life, it works but the risk is increased. Don't consume expired food because even food within its shelf life may have a shorter shelf life due to open packaging or improper storage, so be extra careful.

Manufacturers may add some chemical ingredients, such as preservatives, in order to extend the shelf life of a product so that it does not undergo sensory changes. Eating them can cause chronic toxicity in humans, especially in children and pregnant women.
