Over time, scientists have run tests to see how long food can last without growing mold, attracting pests, etc. The expiry date that is on a package is an estimate of that amount of time. However, some people use methods such as freezing, dehydrating, canning, vacuum sealing, and others to keep food fresher longer.

It is important so that people are aware of when their food is no longer safe to consume.

Many foods have an expiry date (called an "expiration date" in the USA) because their ingredients will spoil if they are left on the shelf for too long. Some products have a very long "shelf life"-- they can be sold for weeks, or even months. But others are "perishable," which means if you do not buy them before their expiry date, they will no longer be healthy and in fact, you might get sick from eating them.

Because the preservatives in them, start to wear off after the date. If it's fruit, well that's probably because after that date, it will start to decompose and become smelly :P.

How long past expiration date for swanson chicken broth?

The date on the broth is NOT an expiration date. There are only a very few foods with an expiration date. They are baby foods. The rest are "best by" or "use by" dates. The manufacturer is saying they "guarantee" maximum quality if consumed by that date. Nothing "magical" happens inside the package on the date on the outside.
