You should not leave the grapes out overnight because they can go bad and start growing bacteria and mold on them. It’s recommended that you don’t leave grapes out longer than 2 hours at room temperature to keep them fresh and avoid bacteria forming on them.

Grapes in clamshells and other containers should always be refrigerated. When grapes are refrigerated on display and not over-stacked, they can be displayed for up to 72 hours before visible shrink occurs.

To keep grapes at their freshest, store them unwashed in a plastic bag in the refrigerator. As noted here, fresh grapes usually keep well for about 1 to 2 weeks in the fridge; you can also freeze grapes for future snacking or use in cooking.

GRAPES – FRESH, RAW Grapes should only be left out at room temperature if being consumed within the same day, as grapes are highly perishable and do not ripen after being picked. Properly stored, grapes will usually keep for about 7 to 14 days in the fridge.

Your Ultimate Guide To How Long Food Can Be Left Out At Room Temp (And When You Should Toss It)

• Vegetables. Depending on the veggie, most can stay on the counter until use (or until overripe).
• Fruit.
• Eggs.
• Meat.
• Cheese/Dairy Products.
• Butter.
• Condiments.
• Baked Goods.

Canned or dehydrated meat: Canned chicken, tuna, salmon, and dehydrated meat like beef jerky can add bulk to your meals. Since the meats come canned or dehydrated, you won’t need to worry about refrigeration.

No Refrigeration Cooking

• Oatmeal.
• Canned tuna, chicken, or ham for an easy protein source.
• Beef or other jerkies and dehydrated meats.
• Energy, protein, or granola bars.
• Pasta, lentils, beans, and other dry, boilable grains and legumes.
• Boxed chicken or vegetable broth.

Some foods have naturally long shelf lives, and if stored properly, will keep for months or years….Stay prepared: Foods with the longest shelf life

• Potatoes. • Shelf life: 2 to 5 weeks.
• Onions. • Shelf life: 1 to 2 months.
• Peanuts.
• Winter squash.
• Apples.
• Tea.
• Powdered milk.
• Beef jerky.

The USDA says food that has been left out of the fridge for more than two hours should be thrown away. At room temperature, bacteria grows incredibly fast and can make you sick. Reheating something that has been sitting at room temperature for longer than two hours won’t be safe from bacteria.

Without a cuticle, eggs need to be kept cold—not for the product itself, but to discourage bacterial growth in and on it. The case for refrigeration, however, is bolstered by the fact that the shelf life of refrigerated eggs is around 45 days, whereas unrefrigerated eggs are good for only about 21 days.

And salmonella can spread quickly when eggs are left out at room temperature and not refrigerated. “A cold egg left out at room temperature can sweat, facilitating the movement of bacteria into the egg and increasing the growth of bacteria,” the USDA states on its website.

Without the cuticle, eggs must be refrigerated to combat bacterial infection from inside. In Europe, it’s illegal to wash eggs and instead, farms vaccinate chickens against salmonella. With the cuticle intact, refrigeration could cause mildew growth and contamination.

Keeping eggs in the fridge cause the growth of bacteria on the shells and this turn and enter the insides of the eggs, in turn making them inedible. Hence, according to many studies, eggs should be kept at room temperature for ideal consumption.

How long can you store fresh eggs at room temperature? Various resources say to store fresh eggs at room temperature for no more than 2 to 3 weeks. However, the recommendation doesn’t stem from food safety alone – but more so to maintain optimal eating quality. As eggs age, their protein structure degrades.

If eggs are left unwashed with the bloom intact, you can place them on your kitchen counter. Unwashed, room temperature eggs should keep for about two weeks. The cooler temperatures increase the shelf life, with eggs keeping for up to three months in the refrigerator.

Simply fill a bowl with cold tap water and place your eggs in it. If they sink to the bottom and lay flat on one side, they are fresh and good to eat. A bad egg will float because of the large air cell that forms at its base. Any floating eggs should be thrown out.
