From the Campbell Soup Company site:

The shelf life of unopened Campbell canned products varies from 1 to 2 years. In order to experience optimal color, flavor, aroma and texture the product should be consumed prior to the end of the month displayed on the product.

I think its like 1-2 weeks or something like that

In most cases no. Canned food usually has a shelf life of 2 years and it's best to dispose of such foodstuffs. Also beware of any damaged cans or ones that have a bulge in them. These are certain signs of contamination and should be disposed of quickly and without question.

When manufacturers produce a product they put an expiration date on it. This does not mean the food is not good after that date because there is a large safety factor added to the expiry date so the food is still good. The message on the container usually says something like "Best if used before 2/2/2009". Although the food is still good, the longer it stays on the shelf the more likely the flavor and taste will diminish. As the post above indicates, if there is visible damage to the can such as bulging it is probably contaminated with a gas generating microorganism and should be discarded without opening.

Condensed milk is a highly shelf-stable milk product made by evaporating much of the water from milk to create a thick, syrupy liquid, and adding sugar to it before canning the milk in a sterilized can. When well made, condensed milk can last unopened on the shelf for up to two years.

I used to buy tea loose from a local shop and kept it in a ziplock. Last night I found some in the back of my cupboard and had a cup with my husband. It was fresh and delicious! We think it was about 4 years old.

After seeds are broken open their outer shells can no longer protect the seed contents and seed nutrients start to degrade. Don't try to store unprotected flours longer than a year. Hermetically sealed in the absence of oxygen, plan on a storage life of 5 years at a stable temperature of 70 degrees F. They could remain usable for up to 50 years if stored below freezing depending on 4 factors: a. Constant temperature b. Product moisture content c. Atmosphere of the storage area d. Container holding the product.

Cereal should be stored in a dry and room temperature climate. No moisture should be near the box or mold could start to form. Most people keep cereal in places such as a cabinet, a pantry or a shelf.

Although garlic contains allicin, a powerful antibiotic and fungicide, that gives garlic a great reputation as a home remedy there are some varieties of mold capable of invading garlic. Common mold infections include penicillium molds and black mold. Such molds render the clove or bulb of garlic unfit for human consumption, as said mold or fungi grow develop a strong resistance to it's antibiotics. Unless you are talking about mold or fungi know to be edible (corn smut, blue cheese mold), just avoid them, regardless of where they grow.

Masa harina has a self life of about 3 months.

If it is a dry tea or tea leaves, no. But, bottled drinks can be sour if the expiration date is several months ago. Turn it over and check the bottom. Many of the companies add sugar, so if anything is floating in it, don't drink it.

If it is not far past the date, and it has been properly stored, in all likelihood it is safe. Just take a sniff, and then a small taste. If it is off at all, throw it out. It should not have any tartness or sour taste. Really, pudding is so cheap, you could always be on the safe side and just go buy some fresh.

When it is mixed with water, the quality of the water, the cleanliness of your utensils, and the product temperature will be factors in how long it will keep. Plan to use it immediately if there's no refrigeration.

Generally, spoiled food will have a noticable (bad) odor, or have some miscoloring from mold or other bacterial growth. Spoiled meat, for example, often turns greyish in color. Spoiled or stale bread and other grain products will grow mold, as will many dairy products like cheese. If you have doubts, don't eat it. Spoiled food can cause some real problems in human digestive systems.

Of course! It's sold as food, why would it not be safe to eat?

Barley is a very popular grain. Pearl barley simply has the hull and bran removed, leaving a whiter less fibrous grain. Barley is eaten in soups, as a porridge, and can be mixed with rice as a grain side dish.
