The company said no, if they are handled correctly. That means if the olives are kept submerged in their brine and kept out of heat and direct sunlight, they will last up to six months at room temperature. If you're looking for a safe period, aim to finish the olives within 3 weeks of opening. Olives that have been continuously refrigerated will generally stay at best quality for about 12 to 18 months. The best way is to smell and look at the olives: if the olives develop an off odor, flavor or appearance, or if mold appears, they should be discarded. Your sense of smell is usually the best way to tell if your olives have gone bad. The olives will begin to have an odor if they are going bad. Their texture and color may also change and they may develop mold if spoiled. You can help capers stay fresh longer by storing them unopened in the pantry where the temperature is always less than 75 degrees Fahrenheit. Once opened, the capers should be kept in the fridge. Be sure to keep the capers submerged in their liquid (brine).

In short, if it smells bad, discard it. Last but not least, the texture and taste. If the taste is okay, they are most likely perfectly safe to eat. Please note that olives over time can lose some of their texture, and if that happens, they work better in cooked dishes than in salads.

Smell the olives. If they do not have a smell or they smell metallic or unpleasant in some way, they are probably bad and should be thrown out. If black olives have white fuzz on them, seem overly greasy and slimy or look patchy and discolored, they are bad.

According to "Keeping Food Fresh" by Janet Bailey, Unopened cans of olives keep up to one year on a cool, dry shelf. Once you have opened a can, store the olives completely submerged in their own liquid in a covered container in the refrigerator for one to two weeks.

If it's been in your fridge for a while, then it is probably OK. Toss the ones with the mold; they have probably acquired off flavor and/or texture. If a lot of the olives are moldy, toss it all. If you see mold or slime under the brine that is Not Good.

Place fresh black ripe olives in containers with 10% brine (100 grams of salt to 1 litre of water). Fill containers to the top, and keep olives under the surface for approximately 6 weeks, or until there is no longer a bitter taste.

While many chemotherapies and targeted therapies cause constipation, some of the others cause diarrhea. Foods like green olives, dark chocolate and yogurt contain probiotics that might help make your system more regular and ease symptoms of diarrhea. Other foods can lead to good digestion as well.

These spots are natural bruising and freckling that occur in picking/harvesting. The olives are still delicious and safe to eat. Then, many companies actually use oxidation to turn green olives black, and then they use Ferrous gluconate to keep them black. These companies use an alkaline medium to spur oxidation.

The combination of added oxygen and gluconic acid gives the olives that black color. The olives are ready to go in a can. Canned food has to be cooked to kill the bacteria. The cooking also takes out a lot of the bitter stuff, which is why canned black olives are so sweet tasting.

Keep the olives refrigerated until ready to use in a martini or other cocktail. Note: Pimento-stuffed Spanish queen olives are sold without brine in tubs in the deli section of some supermarkets. They are also sold in jars in the pickle aisle of most supermarkets.

Make a brine with the same ratio of 1 1/2 tablespoons salt to 1 pint water. Stir in the red wine or apple cider vinegar. Pour the brine over the olives. Tightly cover the olives and store in the refrigerator or a cool cellar or garage for up to 1 year.

Speaking of olives, when the jar of green olives gets a little white film on top, don't toss them. This is known as "mother" and is not harmful. You can scoop it off with a spoon, and then add a teaspoon of vinegar to the jar to help prevent it from forming again.

Are olives edible off the branch? While olives are edible straight from the tree, they are intensely bitter. Olives contain oleuropein and phenolic compounds, which must be removed or, at least, reduced to make the olive palatable.

These Kalamata-style water-cured olives can be stored in the finish brine in a cool, dark place or refrigerated for about 1 year if the container remains airtight. Use pickling salt.

The white spots that you see on the olive are a naturally occurring result of the olive undergoing fermentation. It is harmless, and does not affect the taste of the olives.
