Chicken is a versatile and affordable meat that is a staple in many households. However, it is important to handle and store it properly to prevent the growth of harmful bacteria that can cause foodborne illnesses. The United States Department of Agriculture (USDA) recommends that raw chicken should not be left out at room temperature for more than two hours, as bacteria can multiply rapidly when chicken is in the danger zone of 40°F to 140°F. Cooked chicken is no different and should also not be left out for more than two hours, or one hour if the room temperature is above 90°F. Eating spoiled chicken can lead to food poisoning, with symptoms including headaches, nausea, vomiting, and diarrhea. So, what happens if you leave chicken out all night? Well, you may be at risk of foodborne illness, and it is recommended that you discard the chicken rather than risk consuming harmful bacteria.

What You'll Learn
Bacteria and food poisoning
Leaving chicken out overnight significantly increases the risk of food poisoning. Bacteria thrive in what is known as the "danger zone", which is a temperature range between 40°F and 140°F (4°C and 60°C). At these temperatures, bacteria multiply rapidly, and cooked chicken should not be left out of the refrigerator for more than two hours, or one hour if the room temperature is above 90°F (32°C).
The same guidelines apply to raw chicken, and it is important to keep chicken either below 40°F (4°C) or above 140°F (60°C) at all times. This can be achieved by storing chicken in a refrigerator or freezer, or by keeping it warm, above 140°F. It is also important to cool chicken to room temperature within two hours before storing it in the refrigerator or freezer, to avoid raising the temperature inside and putting other foods at risk.
Chicken is a major source of Salmonella, which is one of the most common causes of food poisoning. Salmonella can enter the lining of the intestines and make it hard for the body to retain water. E. coli is another common bacteria found on chicken, which can cause severe diarrhea and other life-threatening illnesses.
Food poisoning symptoms range from mild to severe, and in severe cases can be fatal. Symptoms can last for days, weeks, or months, and can include nausea, vomiting, diarrhea, dehydration, bloody stools, and neurological symptoms. In some cases, food poisoning can lead to kidney damage or failure, meningitis, arthritis, brain damage, and nerve damage.
It is not possible to tell if chicken has gone bad by its appearance, taste, smell, or texture. Spoiled chicken may have an unpleasant odor, a slimy or sticky texture, or discoloration, but these signs are not always present. Reheating chicken that has been left out may not kill all bacteria and toxins, and it is generally advised to throw out chicken that has been left out for more than two hours.

Food storage safety
Storing Raw Chicken:
- Room Temperature Storage: Raw chicken should not be left out at room temperature for more than two hours. If the room temperature exceeds 90°F (32°C), the safe limit decreases to one hour. This is because bacteria can multiply rapidly when chicken is in the "danger zone," a temperature range between 40°F (4°C) and 140°F (60°C).
- Refrigerator Storage: It is recommended to thaw frozen chicken in the refrigerator overnight. This ensures the chicken remains within a safe temperature range.
- Alternative Thawing Methods: If you're short on time, you can thaw chicken using a cold-water bath, changing the water every 30 minutes. You can also use a microwave, but this may not be as effective.
Storing Cooked Chicken:
- Room Temperature Storage: Similar to raw chicken, cooked chicken should not be left out for more than two hours at room temperature. If the temperature exceeds 90°F, the safe limit is one hour. This applies to cooked chicken at picnics, barbecues, or indoor gatherings.
- Refrigerator and Freezer Storage: To store cooked chicken, it should be cooled to room temperature within two hours before placing it in the refrigerator or freezer. Storing it correctly ensures the safety of other foods in the fridge or freezer. Use airtight containers or heavy-duty plastic wrap to maintain quality.
- Reheating: When reheating cooked chicken, ensure it reaches an internal temperature of at least 165°F (74°C) to kill any bacteria. Reheating does not always make chicken safe to consume, as some bacteria and their toxins may remain.
Signs of Spoilage:
It is important to note that you cannot always tell if chicken is safe to eat by its appearance, taste, smell, or texture. However, spoiled chicken may exhibit certain signs:
- Smell: Fresh chicken has a mild or slightly salty smell, while spoiled chicken may have an unpleasant, sour, rotten, or ammonia-like odour.
- Texture: Fresh chicken feels firm and slightly springy. Spoiled chicken may be slimy, sticky, mushy, or too soft.
- Colour: Fresh chicken is pinkish or whitish. Discolouration, such as greenish or greyish hues, or dark spots, may indicate bacterial growth.
In summary, to ensure food storage safety, it is crucial to adhere to the recommended time limits for leaving chicken out and to store it at the appropriate temperatures. By following these guidelines, you can significantly reduce the risk of foodborne illnesses caused by bacteria such as E. coli and Salmonella.

Chicken thawing
Recommended Thawing Methods
The best way to safely thaw chicken is by planning ahead and using your refrigerator. Place the frozen chicken in the refrigerator overnight to allow it to thaw gradually and safely. This method helps maintain a temperature below the "danger zone," which is between 40°F and 140°F, where bacteria can multiply rapidly.
If you're in a hurry, you can use a cold-water bath to thaw chicken faster. Submerge the chicken in a sealed bag in a bowl of cold water, changing the water every 30 minutes. This method keeps the chicken at a safe temperature while accelerating the thawing process.
You can also use the microwave to thaw chicken, but it requires close monitoring to avoid partially cooking it or creating uneven hot spots. When using the microwave, ensure the chicken reaches an internal temperature of at least 165°F to kill any bacteria that may have grown during storage.
Safety Precautions
Leaving chicken at room temperature for extended periods is unsafe. Whether raw or cooked, chicken should not be left out of the refrigerator for more than two hours. If the room temperature exceeds 90°F, the time limit decreases to just one hour. These guidelines apply to both whole chickens and cut-up chicken pieces.
It's important to note that you cannot determine whether chicken has gone bad solely by its appearance, taste, smell, or texture. Bacteria growth may be invisible to the naked eye, and consuming chicken that has entered the "danger zone" can lead to food poisoning, which can have severe and even life-threatening consequences.
To ensure food safety, always follow these guidelines for thawing and storing chicken. By keeping chicken at safe temperatures and practicing proper handling, you can significantly reduce the risk of foodborne illnesses.

Signs of spoiled chicken
Leaving chicken out overnight puts it in the "'temperature danger zone', a range between 40°F and 140°F where bacteria can multiply rapidly. It is generally advised that perishable food should not be left out at room temperature for more than 2 hours, or 1 hour if the temperature is above 90°F.
- Discolouration: Raw chicken should have a light pink colour with white fatty pieces. If the flesh has turned grey or green, or if the fat has turned yellow, this is a sign of spoilage.
- Odour: Fresh, raw chicken will have a very mild smell or none at all. Spoiled chicken will have a foul odour.
- Texture: Fresh, raw chicken has a glossy, soft, and shiny texture. It should not be slimy, sticky, or tacky. If your hands feel slimy after touching raw chicken, this is a sign it has gone bad. Cooked chicken is firmer and drier than raw chicken. If you notice increased softness, sliminess, or stickiness, it is likely no longer safe to eat.
- Foreign substances: If you notice any visible signs of spoilage, such as mould growth or foreign substances on the chicken, it should be discarded.
Remember, some signs of bacterial growth may be undetectable, so it is critical to cook chicken to a proper internal temperature of 165°F or 74°C. When in doubt, throw it out!
