- **Methods**: The internal organs are removed; this process may be performed manually or with the help of machines. Care is taken to avoid contamination.

### 7. **Inspection and Grading**
- **Materials**: Inspection tools and equipment.
- **Methods**: Carcasses are inspected for quality and safety. Government inspectors check for signs of disease, contamination, and other defects. Grading may be done based on size and quality.

### 8. **Chilling**
- **Materials**: Refrigeration units, ice, and chilling tanks.
- **Methods**: After evisceration, the carcasses are chilled rapidly to inhibit bacterial growth. This is usually done through immersion in cold water or air chilling.

### 9. **Cutting and Deboning**
- **Materials**: Knives, saws, and cutting machines.
- **Methods**: Carcasses are cut into different cuts (e.g., breasts, thighs, wings) and may be deboned for further processing.

### 10. **Packaging**
- **Materials**: Vacuum sealers, shrink wrap, and labels.
- **Methods**: Processed chicken is vacuum-sealed and packaged for distribution. Labeling includes necessary information such as weight, expiration date, and handling instructions.

### 11. **Storage and Distribution**
- **Materials**: Refrigerated trucks and storage facilities.
- **Methods**: Finished products are stored under refrigeration and transported to retailers or consumers under cold chain logistics to maintain safety and quality.

### 12. **Quality Control**
- **Materials**: Testing kits, microbiological assays, and quality measuring tools.
- **Methods**: Routine testing for microbial contamination (e.g., Salmonella, E. coli) and other pathogens. Continuous monitoring of processing conditions ensures adherence to food safety standards.

### Considerations
- **Hygiene**: Throughout the process, strict hygiene practices are crucial to prevent contamination.
- **Regulatory Compliance**: Adherence to local, national, and international food safety regulations is mandatory.
- **Animal Welfare**: Compliance with welfare regulations is important throughout the entire processing workflow.

These processes combine to produce safe, high-quality chicken products for consumers. Each step must be carefully managed to ensure food safety and quality.

### Manual Chicken Processing: Materials and Methods

Processing chicken manually involves a series of thoughtful and careful steps to ensure that the birds are handled safely and that the final product meets quality standards. Below is a detailed description of the materials and methods used in manual chicken processing.

#### 1. **Receiving and Inspection**
- **Materials**:
- Clean, insulated containers for transporting chickens.
- Thermometers to check temperature.
- Gloves and protective clothing for workers.
- **Methods**:
- Upon arrival, each batch of chickens is inspected visually for signs of illness or injury.
- Workers check the temperature of the birds to ensure they have been kept at safe levels during transport.
- Chickens are moved to a clean, cold storage area until processing begins.

#### 2. **Stunning**
- **Materials**:
- Manual stunning devices or a hammer (used in some traditional methods).
- **Methods**:
- To ensure the humane treatment of the chickens, each bird is gently restrained and stunned using a device or method that renders the chicken unconscious before slaughter. A common manual method is a quick blow to the head.

#### 3. **Slaughtering**
- **Materials**:
- Sharp knives or blades.
- A designated slaughter area equipped with hooks or rails for hanging.
- **Methods**:
- Once stunned, the chickens are hung upside down by their feet.
- A careful cut is made at the throat to allow the blood to drain out. The bleeding process is monitored to ensure the birds are fully drained.

#### 4. **Scalding**
- **Materials**:
- A large pot or container filled with hot water (around 140°F to 160°F).
- **Methods**:
- After slaughter, the birds are immersed in the hot water for a brief period (typically 30 seconds to 2 minutes).
- This process helps loosen the feathers, making plucking easier.

#### 5. **Plucking**
- **Materials**:
- Manual plucking tools, such as plucking fingers or simply gloved hands.
- **Methods**:
- After scalding, workers manually pluck the feathers from each chicken, starting with the larger feathers and then moving to the smaller ones.
- This process is done with care to avoid damaging the skin of the bird.

#### 6. **Evisceration**
- **Materials**:
- Knives and gutting tools.
- Clean work surfaces for processing.
- **Methods**:
- Once plucked, the bird is placed on a clean surface for evisceration.
