A hard boiled egg can be kept safely at room temperature for approximately two hours. Refrigerate any hard boiled eggs that will not be eaten immediately; doing so will prevent spoilage and potential food-borne illness.
The shelf life of almonds varies from one year for dry roasted pieces to three years for raw almonds in their shells. Shelf life is affected by processing methods, moisture and the size of the pieces.
Hard boiled eggs have a shelf life of one week if stored in the refrigerator or two hours if left out at room temperature. The protective waxy coating on the eggshell is stripped away in the hard boiling process, leaving it susceptible to bacterial contamination.
The unrefrigerated shelf life of cheese depends on its moisture content. Harder cheeses, such as Parmesan or Romano, have less moisture than soft cheeses like brie or ricotta. Soft, moist cheeses should not be left out for more than two hours. Hard grating cheeses can last longer.
One can safely eat refrigerated eggs three to four weeks after the sell-by date. Refrigerated egg substitutes maintain freshness three to four days after the sell-by date. Egg whites stay fresh in the refrigerator for two to four days, while egg yolks last one to two days.
Yogurt is safe to eat after being unrefrigerated for 24 hours or less. The most common way in which unrefrigerated yogurt goes bad before its "best before" date is the formation of mold on the surface.
Take-out pizza from locations like Pizza Hut and Dominoes can be left out unrefrigerated for up to 24 hours. Pizza tends to become dry and hard when it sits at room temperature for too long.
Cooked beef should be refrigerated within two hours to maintain its safety. If the air temperature is above 90 degrees Fahrenheit, cooked meat should be refrigerated within one hour.
A baked apple pie can be stored unrefrigerated and at room temperature for up to two days. Once the pie has been cut into, it should be covered with foil or plastic wrap. An unbaked apple pie must be stored in the refrigerator or frozen.
The total time needed to boil eggs is between 20 and30 minutes. Hard-boiled eggs require 12 minutes of cooking time after the water begins to boil.
