It's a common misconception that chicken with a pink tinge is undercooked and unsafe to eat. While it's understandable to be cautious due to the dangers of foodborne illnesses like salmonella, the presence of pink in chicken doesn't always indicate that it's undercooked or unsafe. In fact, according to the USDA, chicken can be safely consumed even with a little pinkness, as long as it has reached the correct internal temperature. This misconception has led to customers unfairly criticizing restaurants for serving raw chicken when it's simply a result of factors like cooking methods, feed, and age of the chicken.

What You'll Learn
Chicken can be cooked and still be pink
It is understandable that people are cautious of eating pink chicken, as undercooked poultry can carry the risk of foodborne illnesses, such as salmonella. However, it is important to note that chicken can be cooked and still be pink.
Firstly, it is worth noting that the protein myoglobin, responsible for storing oxygen in muscles, is found in higher amounts in chicken legs and thighs, categorised as dark meat. Myoglobin mixes with water to form "myowater", a pink-hued liquid often found in raw meat packaging. Myoglobin can also leak from bones during cooking, staining the surrounding meat. This is more common in younger chickens, as they have thinner skin and more permeable bones.
Secondly, certain cooking methods, such as smoking, can result in a pink tint, known as a smoke ring. This is caused by nitric oxide in the smoke, preventing myoglobin from turning brown. Freezing chicken can also cause pink colouring, as ice crystals puncture the bone and release bone marrow, which contains myoglobin.
Additionally, the way a chicken is stored, its feed, and the cooking temperature can all influence its colour. For example, introducing citrus or vinegar to the meat can lower the pH, reducing the risk of a pink hue.
Therefore, while it is essential to exercise caution when consuming chicken, relying solely on colour to determine doneness may not always be accurate. Using a meat thermometer to check the internal temperature is a more reliable method, as it directly indicates whether the meat has reached a sufficient heat level to kill harmful bacteria. A finished temperature of 160ºF to 165ºF is recommended for chicken.

The dangers of undercooked chicken
Undercooked chicken is a major source of foodborne illnesses, with about 1 million people in the United States getting sick from contaminated poultry each year. Consuming raw or undercooked chicken can cause food poisoning if the chicken is contaminated with certain bacteria.
Food poisoning symptoms include abdominal cramping, diarrhea, and vomiting. Food poisoning can occur within hours or days of eating contaminated food, and the timeframe depends on the specific bacteria. If you believe you have consumed raw chicken, it is best to wait and see if you develop symptoms.
Other illnesses that can be caused by eating raw chicken include reactive arthritis, septicemia, and Guillain-Barré syndrome (GBS). GBS is a rare neurological disorder that causes the immune system to attack the peripheral nervous system, resulting in numbness, muscle weakness, pain, and problems with balance and coordination.
To ensure that chicken is cooked properly, it should be heated to an internal temperature of 165 °F. This high temperature kills bacteria and significantly lowers the risk of food poisoning. It is important to use a food thermometer to check the internal temperature, as color is not a reliable indicator of doneness. Chicken that is fully cooked may still have a pink tinge due to factors such as the presence of myoglobin, a protein that gives meat a pink hue, or the young age of the chicken, which can result in pigment from the bone marrow seeping into the surrounding area.
Proper handling and storage of raw chicken are also important to prevent foodborne illnesses. Raw chicken should be stored on the bottom shelf of the refrigerator in a sealed container or securely wrapped to prevent leakage of juices. Hands should be washed with soap and water for at least 20 seconds before and after handling raw chicken, and all utensils, chopping boards, and work surfaces should be thoroughly cleaned after preparing raw chicken.

Why cooked chicken may be pink or bloody
It is understandable that people are cautious about eating pink chicken, as undercooked poultry can cause foodborne illnesses such as salmonella and campylobacter. However, it is important to note that the presence of a pink tinge in cooked chicken does not always indicate that it is undercooked or unsafe to eat.
Firstly, the protein myoglobin, which is responsible for transporting oxygen in the body, can cause pink spots in chicken, especially in the legs and thighs, which are classified as dark meat. Myoglobin is found in higher concentrations in these areas because it helps muscles that do a lot of work. When myoglobin mixes with water, it forms "myowater," a pink-hued liquid often found in packages of raw meat.
Secondly, according to the USDA, young chickens have bones that have not completely hardened. As a result, pigment from the bone marrow can seep through the bones and into the surrounding area, leading to a dark or bloody appearance in the cooked meat. Freezing can exacerbate this issue, as ice crystals can puncture the bone and release more marrow. Additionally, young chickens have less fat under their skin, allowing more oven gases to penetrate the meat and create a pink tint.
Certain cooking methods can also contribute to the pink colour. For example, the nitric oxide present in smoke can prevent myoglobin from turning brown, resulting in the coveted "smoke ring" in smoked or grilled foods. Similarly, nitrates and nitrites used as preservatives or occurring naturally in the feed or water supply can cause a pink colour.
To ensure that chicken is safely cooked, it is recommended to use a meat thermometer to check the internal temperature. The USDA recommends an internal temperature of 165 degrees Fahrenheit for poultry to reduce the risk of foodborne illness. However, relying solely on colour to determine doneness may not always be accurate.

How to check if chicken is cooked
It is a common misconception that chicken with a pink tinge is undercooked and unsafe to eat. In reality, this is often not the case, and the chicken may be perfectly cooked. The presence of pink juices or meat does not necessarily indicate that the chicken is undercooked or unsafe to eat, according to the USDA.
So, how can you check if chicken is cooked?
Firstly, it is important to note that temperature is the most accurate way to determine if chicken is cooked. The internal temperature of chicken should reach 165 degrees Fahrenheit to be considered cooked through. Using a meat thermometer is the best way to ensure accuracy.
If you do not have a meat thermometer, there are other ways to check if your chicken is cooked:
- Observe the juices: Pierce the thickest part of the chicken with a knife or fork and check the colour of the juices. If the juices are pink, the chicken may need more time. If the juices are clear, the chicken is likely cooked.
- Check the colour of the meat: Cut into the thickest part of the meat and check the colour. If the meat is white or opaque, it is likely cooked. If it is pink, it may need more time.
- Evaluate the texture: Chicken that is slightly undercooked will be very tender, similar to a rare steak. Overcooked chicken will be stringy and dry. Aim for a texture that is in between these two consistencies.
- Size: As chicken cooks, the proteins shrink. If the chicken is the same size as its raw state, it likely needs more time.
- "Smash test": This involves smashing the largest piece of chicken on a plate with a fork to check the inside. If there is any pinkness, it needs to be cooked further.
It is important to note that cooking methods and cuts of meat can also affect the colour of chicken. Dark meats like thighs and legs may have a pink tinge if they are smoked or baked due to the higher concentration of myoglobin in these cuts. Freezing, brining, and cooking methods can also contribute to a pink colour.
While it is possible for chicken to be safely cooked with a slight pink tinge, it is always better to be cautious when it comes to food safety. If you are unsure, it is best to cook the chicken for a little longer to ensure it is fully cooked.

The impact of chicken age and feed on its colour
It is a common misconception that chicken with a pink tinge is undercooked or unsafe to eat. According to the USDA, a little pink in chicken does not mean it is undercooked or unsafe to consume. In fact, the true indicator of whether chicken is cooked is its internal temperature, which should be 165 °F.
The colour of meat and poultry can be influenced by several factors, including the age of the animal. Meat from older animals tends to be darker because the myoglobin level increases with age. Myoglobin is a protein responsible for the majority of the red colour in meat. When mixed with oxygen, it becomes oxymyoglobin, which produces a bright red colour. Younger birds' meat often shows more pink because their thinner skins allow oven gases to reach the flesh. Older poultry may still have pink spots where fat is absent from the skin.
Chicken feed can also influence the colour of the meat. Previous research has demonstrated that feed colour can increase or decrease feed consumption in broilers, thereby affecting body weight gain during growth. For example, turkeys preferred green colours, while White Leghorns preferred blue feed the most and red the least. However, when given a choice, broiler chicks preferred non-coloured feed.
In addition, the cooking method can affect the colour of cooked chicken. For instance, chicken cooked using a brine and smoking method may result in a light pink colour throughout, known as a "smoke ring".
