Raw chicken is typically light pink with white pieces of fat, though some color variation is normal. For example, the chicken may exhibit a slight darkening or fading of the pink flesh due to oxidation. However, if the chicken has turned grey, green, or yellow, or if it has a foul smell or slimy texture, these are signs of spoilage. To ensure food safety, use a food thermometer to check the internal temperature of cooked chicken, which should reach at least 165 °F.

Raw chicken should be light pink with white fat pieces
It is important to know how to identify whether raw chicken is safe to eat or not. Raw chicken should ideally be light pink with white fat pieces. This is because the pink colour comes from myoglobin, a protein that is purplish in colour when fresh and protected from contact with air, and turns cherry-red when exposed to oxygen. However, when meat is stored in the refrigerator, it may not be exposed to oxygen below its surface, leading to a grayish-brown colour that is safe to consume.
While the colour of raw chicken is an important indicator of its freshness, other factors such as smell, texture, and storage practices also play a role in determining its safety. Fresh raw chicken typically has a very mild or non-existent odour, and a glossy, soft, and moist texture. It should not be slimy, sticky, or tacky.
If the raw chicken has a foul smell, or has turned yellow, green, or gray, it has likely gone bad and should be discarded. Mild colour changes, such as slight darkening or fading of the pink flesh, are normal and can occur due to the conversion of oxymyoglobin to metmyoglobin after exposure to oxygen. However, fresh chicken should only be stored in the fridge for 1-2 days, and if not cooked within this time, it should be frozen.
When cooking chicken, the raw pinkish hue changes significantly. Different cooking methods, such as grilling, barbecuing, or poaching, can result in varying levels of browning on the outside and inside of the chicken. Marinades containing ingredients like soy sauce or spices can also stain the meat, leading to a darker exterior. However, regardless of colour variations, it is crucial to monitor the internal temperature of the chicken to ensure it is cooked safely. Consuming undercooked chicken can lead to foodborne illnesses caused by bacteria such as Salmonella and Campylobacter.
In summary, raw chicken should ideally be light pink with white fat pieces, but other factors such as odour, texture, and storage practices should also be considered to ensure its safety. When cooking chicken, the colour changes significantly, and it is important to use a food thermometer to monitor the internal temperature to prevent foodborne illnesses.

Browning may be a result of grilling or barbecuing
Raw chicken is typically light pink with white fatty pieces. However, it is important to note that raw chicken can vary in color, and mild color changes are normal. For example, exposure to oxygen can cause the pink pigment in chicken to fade, resulting in a whitish or brownish hue. Other factors that can affect the color of raw chicken include the chicken's diet, age, and breed.
When it comes to cooking chicken, different cooking methods can also impact the final color of the meat. Grilling or barbecuing, for instance, involves direct heat, which can cause browning on the outside of the chicken while keeping the inside tender. This browning is a result of a chemical reaction between the heat and the myoglobin in the meat. Myoglobin is a protein that gives meat its red color, and when exposed to heat, it can undergo a chemical change, resulting in a brown or golden-brown crust on the chicken.
The type of chicken and the presence of marinades can also influence the color of cooked chicken. For example, certain ingredients in marinades, such as soy sauce or spices, can stain the meat and lead to a darker exterior. On the other hand, poaching chicken tends to result in a paler color due to the retention of moisture.
While color can provide some indication of doneness, it is not always a reliable indicator. The safest way to determine if chicken is cooked properly is to use a meat thermometer. For whole chickens or turkeys, it is important to check the internal temperature in the innermost part of the thigh and wing and the thickest part of the breast. The chicken is safely cooked when all parts reach an internal temperature of at least 165 °F.
In addition to color and temperature, other factors such as smell and texture can also indicate whether chicken is safe to consume. Fresh raw chicken should have little to no odor and a soft and moist texture. If the chicken has a foul smell or feels slimy, sticky, or tacky, it is likely spoiled and should be discarded.

Marinades with soy sauce or citrus juices can cause colour changes
Raw chicken is usually a light pink color with white pieces of fat. However, it is normal to observe slight color changes in the chicken's flesh. For instance, the pink flesh may become slightly darker or fade, which is typically the result of oxymyoglobin converting to metmyoglobin upon exposure to oxygen. This does not always indicate spoilage, but it may suggest that the chicken is not as fresh.
Marinades containing acids, such as vinegar or lemon juice, or certain enzymes from fruits like papayas, kiwis, or pineapples, can cause color changes in chicken. The acidic nature of these marinades can denature the surface proteins of the meat, leading to a tougher texture. This is a similar reaction to that observed when using a citrus juice marinade to prepare ceviche. While it may not affect taste or texture significantly, over-marinating can have adverse effects.
Soy sauce and citrus juice marinades are a popular choice for chicken. This combination also includes ingredients like garlic, ginger, vinegar, sugar, and citrus juice. The chicken is marinated for 12 hours to 2 days, after which it is roasted until deep brown and cooked through. The acidic nature of the citrus juice in this marinade can contribute to color changes in the chicken, similar to the effects of other acidic marinades.
In addition to color changes, it is important to consider other factors when determining if chicken is safe to consume. These include appearance, smell, and texture. Fresh raw chicken should have a glossy and somewhat soft texture, without being slimy, sticky, or tacky. It should also have little to no odor, and any noticeable foul smell could indicate spoilage. Mold or color changes can be difficult to spot if the chicken is seasoned or dressed, so it is recommended to consume it within 3 days of cooking.
While color changes in chicken can occur due to marinades with soy sauce or citrus juices, it is important to follow safe food handling practices to reduce the risk of foodborne illness. This includes proper storage, preparation, and cooking of chicken to ensure it is safe for consumption.

Raw chicken may turn grey due to oxidation and loss of oxygen
Raw chicken is usually light pink with white fatty pieces. However, it may turn grey due to oxidation and loss of oxygen. Oxymyoglobin, a red protein and pigment, converts to metmyoglobin when exposed to oxygen, resulting in a colour change. This does not necessarily indicate spoilage, but it may suggest that the chicken is not as fresh.
Oxidation is a chemical change that occurs in myoglobin due to oxygen content. It is a normal change during refrigerator storage and does not imply that the chicken is unsafe to eat. However, it is important to note that oxidation can also be caused by exposure to light and oxygen, which can contribute to microbial spoilage.
Other factors that can affect the colour of raw chicken include breed, exercise, age, and diet. Younger poultry, for example, may have less fat under the skin, resulting in a bluish cast. The yellow skin of older poultry could be due to marigolds in the feed.
It is important to consider other signs of spoilage when determining if chicken is safe to eat. A foul smell, slimy texture, or changes in colour to yellow, green, or grey indicate that the chicken has gone bad and should be discarded. Raw chicken should also be tossed if it is past its use-by date or has been stored improperly.
Cooked chicken that turns grey during cooking is likely due to smoke and does not necessarily indicate spoilage. However, it is important to use a food thermometer to check the internal temperature of cooked chicken to ensure food safety.

Colour is not an indicator of doneness; use a food thermometer
Raw chicken usually has a light pink colour with white pieces of fat. However, colour is not a reliable indicator of whether raw chicken has gone bad. Fresh chicken can sometimes exhibit mild colour changes, such as a slight darkening or fading of the pink flesh, which is a normal result of oxymyoglobin exposure to oxygen. This can indicate that the chicken is not as fresh, but it is not a sign of spoilage.
Colour is also not a reliable indicator of whether cooked chicken is safe to eat. Chicken that has been safely cooked can vary in colour from white to pink to tan. This is due to chemical changes that occur during cooking, as oven gases react with haemoglobin in the meat tissues.
The only reliable way to ensure that chicken has been cooked to a safe minimum internal temperature is to use a food thermometer. This helps to ensure that harmful microorganisms have been destroyed. The internal temperature of a whole chicken or turkey should be checked in the innermost part of the thigh and wing and the thickest part of the breast. All parts of the chicken should reach at least 165 °F.
It is important to calibrate your food thermometer and place it properly to get an accurate reading. Place the thermometer in the thickest part of the food, making sure not to touch bone, fat, or gristle. You should also clean your food thermometer by hand with hot, soapy water after each use to prevent the spread of harmful bacteria.
