For this reason refrigerated meat is safe to eat for a significantly shorter amount of time than frozen meat. The temperature ranging from 40 to 140 (4.4℃ to 60℃) is referred to as the “danger zone” by food safety experts. It is in this “zone” that bacteria increase, nearly doubling in a mere 20 minutes. A home refrigerator should be set at 40 or colder to keep meat safe for the maximum amount of time. It is important to note that there are two different groups of bacteria that affect refrigerated meat. The first, pathogenic bacteria (致病细菌), make us sick, while the second, spoilage bacteria (腐坏细菌), make our food go bad and stink out our refrigerators. By sight, smell and taste, you cannot identify whether meat is harboring pathogenic bacteria, unlike meat affected by spoilage bacteria. In a refrigerated state, spoilage bacteria can grow. This is proven by the fact that all food in a refrigerator eventually spoils. Spoiled food won't make you sick—it might taste bad, but unless it has pathogenic bacteria, your digestive system is in the clear. Unrefrigerated meat, if left out on the counter for a few hours, might smell and look fine, but may be full of pathogenic bacteria. During a power cut, food stored in a refrigerator that rises in temperature to over 40 for more than two hours should be removed. Also, due to temperature change, don't store meat on the door. It is important to maintain your refrigerator's temperature by keeping the door closed as much as possible. As always, follow proper cooking instructions when preparing any meat to kill any potentially harmful bacteria. The following is a list of how long certain refrigerated food will be safe to eat: cooked leftovers, four days; raw eggs, three to five weeks; hard­boiled eggs, one week; salads, such as egg, macaroni, potato or tuna, three to
