Chicken is a versatile and nutritious food staple for many households. However, it can spoil, affecting its taste and texture and potentially causing foodborne illnesses. One of the ways to tell if chicken has gone bad is by its smell. Raw, fresh chicken usually has little to no odour, with a very mild smell that is distinct from spoiled chicken. Spoiled chicken has a strong, sour, or sulfur-like smell similar to rotten eggs or ammonia. While smell is a good indicator, it is not always reliable, and other signs of spoilage, such as texture and colour changes, should also be considered.

Raw chicken can have a slight smell
It is understandable to be concerned about the smell of raw chicken. After all, it is a versatile, nutritious food that is a staple in many households. However, it is important to know that raw chicken can have a slight smell, and this is usually normal.
Fresh, raw chicken generally has little to no odour. It may have a very mild, light chicken scent, which some people describe as slightly "fleshy" or "meaty". Others have likened the smell to "sweet milk". This scent is not overpowering and is only noticeable if you hold the meat up to your nose.
However, it is crucial to distinguish between the natural smell of raw chicken and the smell of spoiled chicken. Spoiled chicken has an unmistakable, strong odour, which may be likened to rotten eggs, ammonia, or simply a pungent, sour smell. If your chicken has a very apparent smell, it is likely spoiled and should be discarded.
Additionally, spoiled chicken may exhibit other signs of spoilage, such as a slimy, sticky, or tacky texture. If your hands feel slimy after touching raw chicken, this is a sign that it has gone bad. Other signs include colour changes, such as a yellow, green, or grey hue.
It is worth noting that some people have a higher sensitivity to smell and may be more inclined to notice even slight odours. If you are ever in doubt about the freshness of your chicken, it is always better to be cautious and discard it.

Spoiled chicken has a strong odour
It is normal for raw chicken to have a very mild smell or none at all. However, spoiled chicken has a strong odour and can smell like ammonia, rotten eggs, or just plain pungent. Spoilage is caused by bacteria, which eat and excrete waste, causing changes in the food that we recognise as spoilage. It is important to note that spoiled chicken may also be slimy or sticky to the touch, and have visible signs of spoilage such as mould growth. If you notice any of these signs, discard the chicken immediately.
To ensure the chicken is safe to consume, it is important to look for certain signs of spoilage before preparing it. Raw chicken should typically be light pink with white fatty pieces. If the flesh has turned grey, green, or yellow, or if there is a slimy residue after touching it, these are indications that the chicken has gone bad.
Cooked chicken should be firm and drier than raw chicken. If you notice any texture changes, such as increased softness, sliminess, or stickiness, it is likely no longer safe to eat. It is recommended to consume cooked chicken within 3-4 days and store it in the refrigerator.
While it is generally safe to rely on smell to determine if chicken is spoiled, it is important to note that people's sense of smell can vary. Therefore, it is advisable to look for other signs of spoilage in addition to smell.
Properly preparing, cooking, and storing chicken is crucial due to its high risk of bacterial contamination. Cooking chicken thoroughly to an internal temperature of 165°F (74°C) for at least 30 seconds will effectively kill any harmful bacteria. Additionally, following safe storage practices can reduce the risk of foodborne illness.

Chicken spoilage is caused by bacteria
It is normal for raw chicken to have a very mild smell or no odour at all. If your chicken has a very apparent smell, such as a sour or sulfur-like odour, it has likely gone bad. Chicken spoilage is caused by bacteria.
Chicken spoilage is primarily caused by psychrotrophic spoilage bacteria, which can multiply under cold conditions. These bacteria are called psychrotrophic because they are able to grow and multiply in low temperatures, such as in refrigerators. Psychrotrophic bacteria are present in very low numbers immediately after slaughter, but they can multiply rapidly and cause spoilage. The most common psychrotrophic bacteria found on spoiled chicken are Pseudomonas fluorescens, putida, or fragi, and Shewanella (formerly a Pseudomonas) putrefaciens. Pseudomonas bacteria are well-suited to spoil chicken because they can break down fat equally well at refrigerator temperatures or room temperature.
Other bacterial groups that cause chicken spoilage include specific spoilage organisms (SSOs) and spoilage-associated organisms (SAOs). SSOs initiate the deterioration process, while SAOs represent all bacterial groups found in meat samples before, during, and after spoilage. The proliferation and interaction of these bacterial groups lead to poultry meat deterioration.
To prevent chicken spoilage, it is important to follow safe storage practices. Raw chicken should be stored in the refrigerator and cooked within 1-2 days. Cooked chicken should be eaten within 3-4 days and should also be stored in the refrigerator. If chicken has been left at room temperature for more than 2 hours, it should be discarded.
Additionally, proper handling, transportation, processing, and storage of chicken meat can help ensure microbial safety and reduce the risk of bacterial contamination and spoilage. Marinades and preservation processes can also be used to extend the shelf life of chicken and prevent spoilage.

Safe storage practices can reduce the risk of illness
It is normal for raw chicken to have a very mild smell, but it shouldn't be slimy, sticky, or tacky. If it has a strong, sour, or sulfur-like smell, it has likely gone bad and should be discarded. Chicken can spoil quickly, so it's important to practice safe storage to reduce the risk of foodborne illnesses.
Firstly, always store chicken in the refrigerator or freezer. Fresh chicken should be stored in the fridge for a maximum of 1-2 days if it's not going to be cooked within that time frame, then it should be frozen. Cooked chicken should be consumed within 3-4 days and should always be refrigerated. It's important to note that freezing does not destroy harmful germs, but it does keep food safe until it is cooked.
Secondly, ensure your refrigerator is set to 40°F (4°C) or below, and your freezer to 0°F (-18°C) or below. Use an appliance thermometer to check. Perishable foods should not be left out of refrigeration for more than two hours, and leftovers should be refrigerated promptly in shallow containers to allow for quick cooling.
Thirdly, always handle chicken with clean hands. Wash your hands with soap and water for at least 20 seconds before and after handling raw chicken. This helps prevent the spread of germs that can cause foodborne illnesses.
Lastly, keep raw chicken separate from other foods. Place it in a sealed container or wrap it securely to prevent leakage. When shopping, place chicken in a disposable bag or at the bottom of the cart to prevent raw juices from contaminating other foods. If you choose to wash your chicken before cooking, do so safely by gently running water over it to reduce splashing.

Cooking chicken kills harmful bacteria
It is normal for raw chicken to have a very mild smell. However, if the chicken has a very apparent smell, such as a sour or sulfur-like odour similar to rotten eggs, it has likely gone bad and should be discarded. Raw chicken should also not be slimy, sticky, or tacky. Fresh raw chicken typically has a glossy and somewhat soft texture.
Chicken can spoil, which can affect its taste and texture and, in some cases, cause foodborne illnesses. Therefore, it is essential to cook chicken properly to kill harmful bacteria and ensure it is safe to consume.
Cooking chicken does kill harmful bacteria, but it is important to note that it may not destroy all bacteria. Some bacteria have adaptable cell walls that can become resistant to heat. Additionally, some bacteria, such as Staphylococcus (staph) and Bacillus cereus, produce toxins that are not destroyed by high cooking temperatures.
To ensure that chicken is cooked to a safe internal temperature, it should be heated to at least 165°F (74°C). This temperature should be measured using a food thermometer to ensure accuracy. The USDA recommends cooking most meats to an internal temperature of at least 145°F (32°C), but this is considered a bare minimum for food safety. For ground beef, the recommended temperature is 165°F (74°C), while for whole cuts of beef and pork, it is 165-170°F (74-77°C). Chicken parts should be cooked to 165-175°F (74-79°C), depending on the amount of fat present.
It is also important to handle chicken properly before cooking to minimize the risk of bacterial contamination. This includes sanitizing hands before preparing food and preventing raw chicken juices from dripping onto other surfaces. Raw chicken should be stored in the refrigerator for no more than 1-2 days if it is not going to be frozen.
