感恩节为11月26日：农业部食品安全指引称冷冻火鸡冷藏解冻每4至5磅约需24小时，20至24磅须11月20日前入冰箱
今年感恩节为11月26日（周四）。美国农业部食品安全检验局（FSIS）的火鸡安全指引经佐治亚大学推广站（University of Georgia Extension）发布称，解冻火鸡只有三种安全方法：在冰箱中解冻、在冷水中解冻、在微波炉中解冻；由于细菌在室温下可迅速繁殖，绝不能在台面上解冻火鸡。以下内容为农业部与推广站发布的食品安全信息，非个体诊疗建议。
冷藏解冻被列为最安全的方法。指引称，在设定为华氏40度的冰箱中，每4至5磅火鸡约需24小时解冻时间，火鸡应放在容器中承接可能漏出的汁液；按整鸡计，4至12磅需1至3天，12至16磅需3至4天，16至20磅需4至5天，20至24磅需5至6天。照此倒推感恩节日期，20至24磅的火鸡最迟应于11月20日前后移入冰箱，16至20磅为11月21日前后，12至16磅为11月22日前后。解冻完成后，火鸡在冰箱中只能再存放1至2天。
冷水解冻速度较快：把整鸡或切块部位连同气密包装或防漏袋浸入冷水，每磅约需30分钟，每30分钟换一次水以保持低温；冷水解冻的火鸡应立即烹制。微波解冻须按烤箱厂家说明操作，一般约为每磅6分钟，解冻后同样应立即烹制。指引提醒，解冻后须取出鸡腔内的内脏包并单独烹制。
烹制方面，指引称烤箱温度不得低于华氏325度；馅料应单独用烤盘烹制，并以食品温度计确认其中心最厚处达到华氏165度。整禽在鸡翅关节、大腿与鸡翅最内侧以及胸部最厚处均达到至少华氏165度时才算安全，有弹出式温度指示器的火鸡也应再用食品温度计在多处复测。火鸡出炉后应静置20分钟。
剩菜处理方面，指引称火鸡应切成小块，火鸡、馅料与肉汁分别装入浅容器，在烹制后2小时内冷藏（气温高于华氏90度时为1小时内）；剩菜应在3至4天内食用或冷冻，冷冻剩菜最佳品质期为2至6个月；复热时须以食品温度计确认达到华氏165度。

With Thanksgiving on November 26, USDA Guidance Puts Refrigerator Thawing at About 24 Hours per 4 to 5 Pounds, With a 20 to 24 Pound Bird Due in the Fridge by November 20
Thanksgiving falls on Thursday, November 26 this year. Guidance from the U.S. Department of Agriculture's Food Safety and Inspection Service, published by University of Georgia Extension, lists three safe ways to thaw a turkey: in the refrigerator, in cold water or in the microwave, and states that a turkey should never be defrosted on the counter because bacteria can multiply rapidly at room temperature. The following is food safety information from USDA and Extension, not individual medical advice.
Refrigerator thawing is described as the safest method. In a refrigerator set at 40 degrees Fahrenheit, about 24 hours of thawing time should be allowed for every 4 to 5 pounds of turkey, with the bird placed in a container to catch leaking juices. For a whole turkey, the ranges are 1 to 3 days for 4 to 12 pounds, 3 to 4 days for 12 to 16 pounds, 4 to 5 days for 16 to 20 pounds and 5 to 6 days for 20 to 24 pounds. Counted back from November 26, a 20 to 24 pound bird should be in the refrigerator by about November 20, a 16 to 20 pound bird by about November 21 and a 12 to 16 pound bird by about November 22. After thawing, the turkey should be kept refrigerated for only 1 to 2 days.
Cold water thawing is faster: the bird or cut-up parts are submerged in cold water in airtight packaging or a leak-proof bag, allowing about 30 minutes per pound and changing the water every 30 minutes to keep it cold. A turkey thawed by the cold water method should be cooked immediately. Microwave thawing follows the oven manufacturer's instructions, generally about 6 minutes per pound, and also requires immediate cooking. The guidance reminds cooks to remove the giblets from the cavity after thawing and cook them separately.
For cooking, the oven should be set no lower than 325 degrees Fahrenheit, and stuffing should be cooked separately in a casserole dish and checked with a food thermometer for 165 degrees Fahrenheit in the middle, thickest part. Whole poultry is safe at a minimum internal temperature of 165 degrees Fahrenheit measured in the wing joint, the innermost part of the thigh and wing and the thickest part of the breast, and a pop-up indicator does not replace thermometer checks. The turkey should stand for 20 minutes after roasting.
For leftovers, the turkey should be cut into small pieces and the turkey, stuffing and gravy refrigerated separately in shallow containers within 2 hours of cooking, or within 1 hour in temperatures above 90 degrees Fahrenheit. Leftovers should be used within 3 to 4 days or frozen, with frozen leftovers keeping best quality for 2 to 6 months, and reheated to 165 degrees Fahrenheit checked with a food thermometer.
