Processing chickens at home requires a series of steps to ensure the final product is safe for consumption. It is important to note that processing poultry is not for everyone, as it can be a graphic process. The first step is to fast the birds for 12-24 hours to ensure their digestive system is empty, which helps prevent contamination during processing. After slaughter, the birds are scalded and then go through feather removal, followed by evisceration, where the internal organs and feet are removed. The carcasses are then cleaned and inspected before being chilled to prevent bacterial growth. The chicken is then cut up into parts, packed in trays, wrapped, and inspected again before being sent through a blast tunnel to receive a chill for extended shelf life.

What You'll Learn
Fasting chickens for 6-24 hours before slaughter
The length of the fast can vary depending on the source. Some recommend a shorter fast of 6-8 hours, while others suggest a longer duration of 12-24 hours. A study on the influence of pre-slaughter fasting time on weight loss, meat quality, and carcass contamination in broilers found that longer feed withdrawal times of 6 to 10 hours resulted in significant weight loss and lighter meat colour. However, a fast of 10 to 11 hours is commonly practised on farms and in abattoirs, with 5 hours of fasting before lairage, 2 to 3 hours of capture, 2 hours of transport, and 1 hour of rest.
It is important to note that chickens should still have access to water during the fasting period. This will help keep them hydrated and comfortable, especially if the fasting duration is on the longer side.
Some people may be uncomfortable with the idea of starving a chicken before slaughter, but it is a recommended practice to ensure a cleaner and safer final product. It is also worth mentioning that the time of day of the slaughter may be less important than other factors, such as the catching and preparation of the chicken.
Overall, fasting chickens for 6-24 hours before slaughter can help improve the efficiency and hygiene of the processing while also reducing the risk of contamination.

Humane slaughter practices
The Humane Methods of Slaughter Act (HMSA) is a United States federal law that requires humane treatment, handling, and slaughter of food-producing animals. While the HMSA does not apply to poultry, the Poultry Products Inspection Act (PPIA) ensures the humane slaughter of birds. The PPIA requires that live poultry be handled using good commercial practices and not be subjected to any form of slaughter other than that stipulated by the act.
There are several practices that can be employed to ensure the humane slaughter of chickens. Firstly, it is important to handle birds with care and consideration. Chickens should be supported and carried individually, and it is recommended to avoid carrying them by their legs to prevent hip dislocation. Before slaughter, chickens should be fasted without food for 6 to 8 hours, while still having access to water. Fasting reduces the feed content in the digestive tract, which helps prevent contamination during processing.
After slaughter, the feathers of the chicken are removed. This begins by scalding the chicken in hot water to loosen the feathers, after which a machine called a "picker" removes the feathers. The evisceration process involves removing the internal organs and feet of the bird. During this process, each bird is inspected by a member of the processing plant and a USDA inspector to ensure quality, food safety, and wholesomeness.
One of the most humane ways to slaughter chickens is through the jugular cut, which also results in a better end product. This method induces a loss of consciousness by anemia of the brain caused by the simultaneous and instantaneous severance of the carotid arteries. It is important to note that cutting the jugular is considered more humane than cutting off the head, as the latter can result in a painful spinal reflex that causes the chicken to flap and flop.

Sanitization and cleanliness
Handling and Preparing Raw Chicken
The first step in maintaining cleanliness is to avoid washing or rinsing raw chicken before cooking. While it may seem logical to equate washing with cleanliness, washing raw meat can increase the risk of cross-contamination. Bacteria from the raw chicken can spread to other foods, utensils, and surfaces, creating an unsafe environment. Instead, it is recommended to assume that raw chicken is contaminated and focus on handling it safely. This includes using separate cutting boards and utensils for raw chicken to avoid cross-contamination with other foods.
Sanitizing Surfaces and Utensils
It is crucial to sanitize all surfaces and utensils that come into contact with raw chicken. Use hot soapy water and a scrub brush to thoroughly clean countertops, cutting boards, knives, and any other tools used during preparation. Pay close attention to removing any residue or bacteria. After cleaning, disinfect the surfaces to eliminate any remaining bacteria. You can use a solution of one tablespoon of bleach mixed with one gallon of water, letting it sit for a few minutes before rinsing with clean water. Ensure that you follow the manufacturer's instructions when using commercial sanitizers or disinfectants.
Hand Sanitization
Proper handwashing is a critical step in maintaining cleanliness. Before and after handling raw chicken, wash your hands thoroughly with warm water and soap for at least 20 seconds to eliminate germs and bacteria. Use hand sanitizer as an extra precaution if soap and water are not readily available. Remember that anything you touch after handling raw chicken could become contaminated, so handwashing is essential to prevent the spread of bacteria.
Storing and Thawing Chicken
To maintain cleanliness, it is important to follow safe handling and storage practices for chicken. Always freeze or refrigerate chicken in its original packaging, following the recommended temperatures and storage times provided by food safety organizations. When thawing chicken, use safe methods such as thawing in the refrigerator, in cold water, or in the microwave. Never leave chicken at room temperature to thaw, as it can increase the risk of bacterial growth.
Cooking Chicken
Cooking chicken thoroughly is the most effective way to destroy any bacteria that may be present. Ensure that chicken is cooked to a safe internal temperature of 165°F. This temperature applies to whole chicken, parts, or ground chicken. Proper cooking ensures that any bacteria are eliminated, making the chicken safe to eat.
By following these sanitization and cleanliness guidelines, you can help prevent foodborne illnesses and ensure the safe processing of chicken.

Evisceration and organ removal
Evisceration is a critical step in chicken processing, involving the removal of internal organs and ensuring product quality and safety. Here is a detailed guide on evisceration and organ removal:
Preparation for Evisceration:
Before beginning the evisceration process, it is essential to have the right tools and ensure proper sanitation. This includes having a sharp knife, poultry shears, and a clean workspace. Wash your hands thoroughly and sanitize all tools and surfaces to prevent contamination. It is also recommended to wear poultry processing PPE kits for added protection.
Making the Initial Incision:
Make an incision around the vent of the chicken, being careful not to puncture the intestines, as this can lead to contamination. The vent cutters used should be properly adjusted to avoid damaging the intestines and ensure accurate cutting. This initial cut creates an opening for the subsequent evisceration process.
Removing Internal Organs:
Using an eviscerating knife or poultry shears, carefully remove the intestines, giblets (heart, liver, gizzard), and other internal organs. It is important to be gentle during this process to avoid rupturing the organs, which can result in meat contamination. The eviscerating spoon is guided along the sternum up to the throat and then turned towards the back to remove the viscera.
Final Cleaning and Inspection:
After removing the organs, rinse the chicken thoroughly with cold water to remove any remaining feathers, dirt, and contaminants. Pay close attention to both the inside cavity and the skin surface. This step helps reduce bacterial populations and ensure a clean product. Once cleaned, the carcasses are inspected by processing plant personnel and, in some cases, a USDA inspector to ensure they meet quality standards and are free from diseases, fecal matter, or bruising.
Chilling and Storage:
After evisceration and cleaning, submerge the chicken in an ice-water bath to quickly chill it to below 40°F, preventing bacterial growth. Dry the bird and place it in the fridge for at least three days to allow rigor mortis to pass. This chilling process helps extend the shelf life of the product.

Industrial chicken processing
Upon arrival at the processing plant, chickens are stunned, slaughtered, and processed. After slaughter, the feathers are removed by first scalding the bird with hot water, then using a machine called a "picker" with rubber "fingers" that rotate to remove the feathers. The evisceration process involves removing internal organs and feet, and the carcasses are cleaned and inspected for diseases, fecal matter, or bruising.
After inspection, the chickens are chilled to a lower temperature to maintain freshness and cleanliness. Microbiological tests are conducted on equipment and products to ensure food safety, including tests for Salmonella. Once the birds are properly tested and chilled, the carcasses are typically cut and deboned to create various products.
To optimize the filleting process after deboning, companies like Marel offer innovative solutions and equipment for all chicken processing stages. Their software enables food processors to collect and utilize data effectively, improving processing results and ensuring full traceability.
