The dangers of thawing chicken at room temperature
Leaving chicken out at room temperature to thaw can be dangerous. This is because, at room temperature, chicken enters what is known as the "danger zone", where bacteria can grow and multiply on it. The "danger zone" refers to temperatures between 40°F and 140°F (4.4°C and 60°C). At these temperatures, bacteria, such as Escherichia coli (E. coli) and Staphylococcus aureus, can multiply rapidly and produce heat-stable toxins that can make you seriously ill, even after the bacteria are killed. Therefore, perishable foods should never be thawed on the counter or left at room temperature for more than two hours.
The safest way to defrost chicken is to place it in the refrigerator, which keeps the chicken cool while it is defrosting, preventing it from getting too warm for too long. When thawing chicken in the refrigerator, it is important to plan ahead, as it can take a full day to thaw even small amounts of frozen chicken. Chicken should be removed from the freezer at least 24 hours in advance and placed in a ziplock plastic bag or airtight container on a low shelf in the refrigerator until fully defrosted. It should then be cooked within 1 to 2 days.
If you are in a hurry, it is safe to cook chicken from frozen. Alternatively, chicken can be thawed in cold water or in the microwave. When thawing chicken in cold water, it is important to place the chicken in a sealed, leak-proof bag and change the water every 30 minutes to ensure it stays cold. When thawing chicken in the microwave, only the amount of chicken needed should be defrosted, as some areas may begin to cook during the thawing process, and it should be cooked immediately after.
To prevent foodborne illness, it is also important to practice good food handling and cleanliness. This includes washing hands, work surfaces, and utensils with hot, soapy water before handling chicken, washing and sanitizing any surfaces that have come into contact with raw chicken, and handling leftovers safely.

Safe ways to defrost chicken
It is unsafe to let chicken thaw at room temperature. Raw or cooked meat, poultry or egg products, as any perishable foods, must be kept at a safe temperature during the defrosting process. As soon as they begin to thaw and become warmer than 40 °F, bacteria that may have been present before freezing can begin to multiply.
In the Refrigerator
The refrigerator method is the easiest, safest, and most efficient way to defrost chicken. It allows the meat to defrost slowly, evenly, and safely. Put the chicken in its original packaging or a zip-top bag, and place it on a plate to catch any drips. It may take a while for the chicken to fully thaw—up to two days or even more, depending on the cut. Your fridge should be at 40°F or lower for this process to be safe.
Cold Water Method
The cold water method is a good option if you need to defrost chicken quickly. Keep the chicken in its packaging or a sealed plastic bag and submerge it in cold water. Change the water every 30 minutes or so to maintain a safe temperature. A three- to four-pound frozen chicken or package of chicken parts will take about two to three hours to thaw this way. If you use the cold water method, the chicken must be cooked immediately after it's thawed and cannot be refrozen without cooking.
Microwave
The microwave method is the quickest way to defrost chicken, but it should only be used if you have no other option. When thawing chicken in the microwave, it must be cooked immediately after, as some parts may have warmed into the "'danger zone' (40°F to 140°F), where bacteria can multiply. The same goes for refreezing—the chicken can only be refrozen after it has been cooked.
Remember, cleanliness is a major factor in preventing foodborne illness. Always wash your hands with warm water and soap for at least 20 seconds before handling chicken, and handle leftovers with care.

How long does it take to thaw chicken in a refrigerator?
Thawing chicken in the refrigerator is one of the safest ways to defrost chicken. It is recommended that you remove the chicken from the freezer at least 24 hours in advance. The time it takes to thaw chicken in a refrigerator depends on the weight and type of chicken. For example, a 5- to 6-pound chicken will take approximately 24 hours to defrost, which is about 4 hours per pound of chicken. Smaller amounts of frozen food, such as a pound of ground meat or boneless chicken breasts, require a full day to thaw. Chicken breasts, bone-in chicken, and whole chickens can take 1 to 2 days to thaw in the refrigerator.
Chicken should be placed on the bottom shelf of the refrigerator to avoid cross-contamination with other items. It should be stored in an air-tight container, a vacuum-sealed container, or a vacuum bag to prevent oxygen from speeding up the spoiling process. The refrigerator should be kept at a constant temperature of 34 to 40 °F, or below.
It is important to note that thawed chicken can be stored in the refrigerator for only 1 to 2 days. If chicken is not going to be cooked within this time, it should be refrozen. Proper thawing techniques are crucial to keep chicken out of the "Danger Zone" of 40 to 140 °F, where bacteria multiply rapidly.
While thawing chicken in the refrigerator is a safe and effective method, it requires planning ahead due to the lengthy time involved. There are alternative methods for defrosting chicken more quickly, such as using cold water or a microwave. However, these methods may impact the quality of the chicken, and the chicken must be cooked immediately after thawing.

Can you cook chicken from frozen?
While it is not recommended to let chicken thaw at room temperature, it is safe to cook chicken straight from frozen using a number of different methods. It is important to note that cooking time will be about 50% longer than if the chicken were cooked from fresh, and the cooking temperature should be lowered to about 350 to 365 °F to balance out the increased cooking time.
The USDA recommends that perishable foods should never be thawed on the counter, or in hot water, and must not be left at room temperature for more than two hours. This is because bacteria may begin to multiply as soon as the chicken becomes warmer than 40 °F. However, chicken can be safely thawed in the refrigerator, in cold water, or in the microwave.
When cooking chicken from frozen, it is important to ensure that the chicken reaches a safe minimum internal temperature of 165 °F. This can be checked using an instant-read thermometer. Cooking chicken from frozen may result in uneven cooking, with the outside becoming overcooked, dry, and tough before the inside reaches a safe temperature. To prevent this, it is recommended to add extra moisture while cooking, such as by brushing the chicken with a moist sauce or poaching the chicken in a liquid.
Chicken can be cooked from frozen in the oven, Instant Pot, air fryer, stove, or grill. However, it should not be cooked from frozen in a slow cooker or microwave, as the slow cooking process may allow the meat to spend too much time in the temperature danger zone, where bacteria is most likely to grow.
While it is possible to cook chicken from frozen, it is generally recommended to defrost the chicken beforehand to achieve the best results.

What are the risks of foodborne illnesses?
Thawing chicken at room temperature is not recommended. The USDA and FDA guidelines advise against it, and for good reason. The "danger zone" for poultry storage is between 40°F and 140°F (4.4°C and 60°C). This is the temperature range in which bacteria multiply rapidly. Room temperature, at 68°F (20°C), falls well within this danger zone.
Leaving chicken to thaw at room temperature increases the risk of foodborne illnesses. Bacteria such as Salmonella, Campylobacter, Clostridium perfringens, and E. coli can survive at room temperature and may multiply quickly if the chicken is left out. These bacteria can lead to food poisoning, causing symptoms such as fever, diarrhea, vomiting, and dehydration, and in severe cases, paralysis, meningitis, and even death.
To safely thaw chicken, it is best to plan ahead and use one of the three recommended methods: in the refrigerator, in cold water, or in the microwave. The refrigerator method is the safest as it keeps the chicken at a cool, constant temperature of 40°F or below. This prevents the chicken from getting too warm for too long. However, it requires time and planning, as a whole chicken can take up to 2 days to thaw in the refrigerator. The cold water method is another safe option, but it should be done with caution to ensure the water stays cold and the chicken doesn't warm up too much. The microwave method is the quickest, but it can lead to warm spots where bacteria may survive, so it's important to cook the chicken immediately after thawing.
Proper handling and cooking of chicken are crucial to preventing foodborne illnesses. It's important to maintain cleanliness, wash hands, and handle leftovers with care. Cooking chicken to a safe internal temperature of 165°F (74°C) will kill harmful bacteria, but it's important to use a thermometer to check the temperature in multiple parts of the chicken to ensure even heating.
The risks of foodborne illnesses are serious, and it is important to follow food safety guidelines to stay healthy. While some people may argue that they have thawed chicken at room temperature with no issues, it is still a risky practice that could lead to dangerous consequences.
