Berries are among the most fragile items in your kitchen because they have thin skins and high moisture. They can develop mold within just a few days if they stay damp.

To keep them fresh, don't wash them until right before you eat them. Store your berries in a single layer on a paper towel inside a breathable container to absorb excess moisture.

Ground meat has more surface area exposed to oxygen than a whole steak, which allows bacteria to grow much faster. It usually stays fresh for only one or two days in the fridge.

If you don't plan to cook it immediately, split it into portions and store it in the freezer.

An avocado can go from rock hard to overripe in a matter of hours. Once they reach that perfect level of softness, they begin to brown and lose their flavor.

If your avocados are ripe but you are not ready to eat them, you can store them in the fridge for a day or two to slow down the ripening process.

Once the airtight packaging of deli meat is opened, the clock starts ticking. These meats are prone to bacterial growth because of their high moisture and protein content.

Most sliced deli meats only stay safe for three to five days. Keep them in a dedicated meat drawer and ensure the bag is sealed completely to prevent the edges from drying.

Bananas produce a gas called ethylene that causes them to ripen and then rot very quickly. If you keep them in a bunch, the gas is concentrated and speeds up the process for every fruit.

Separate the bananas and wrap the stems in plastic wrap or foil to slow the gas release. This small trick can give you several extra days.

Raw fish only lasts about three days in the fridge before spoiling, so it's best to purchase fish the same day you plan to eat it.

Certain types of fish, like salmon, can be cured to make it last longer. You can also store fresh fish in the freezer for future use.

Once opened, milk only lasts for about a week in the fridge. Milk must stay consistently cold in order to stay fresh. It should not be store in the door of the fridge where it can be exposed to warm air.

For best results, store milk in the back of the fridge where the temperature is the coldest.

Pre-washed salads often turn slimy quickly because of the moisture trapped inside the plastic. The lack of airflow causes the delicate leaves to break down.

To extend their life, open the bag and place a dry paper towel inside to soak up condensation. Transferring the greens to a hard plastic container can also prevent the leaves from getting damaged.
