The **correct food temperatures** are crucial in a kitchen to ensure food safety and prevent foodborne illnesses. Below is a comprehensive guide to **food temperature ranges** for different stages of food handling, including cooking, cooling, storage in chillers and freezers, and the **danger zone** where bacterial growth is rapid.

### 1. **Cooking Temperatures (Internal Temperature of Food)**

The internal temperature of food during cooking is crucial to kill harmful bacteria and pathogens. The U.S. Food and Drug Administration (FDA) provides the following safe cooking temperatures for various foods:

- **Poultry (whole, parts, ground)**: **75°C (165°F)**
This includes chicken, turkey, duck, and other poultry.

- **Ground meats (beef, pork, veal, lamb)**: **71°C (160°F)**
For ground meats, it is important to ensure the internal temperature reaches this level to ensure pathogens are eliminated.

- **Beef, pork, veal, lamb steaks, roasts, and chops**: **63°C (145°F)**
After reaching this temperature, allow the meat to rest for at least **3 minutes** before serving.

- **Fish and shellfish**: **63°C (145°F)**
Fish should be cooked until it is opaque and flakes easily with a fork.

- **Eggs (to be served immediately)**: **71°C (160°F)**
Eggs should be cooked until the yolk and white are firm. For egg dishes like scrambled eggs, they should be cooked to 71°C to ensure safety.

- **Hot dogs and pre-cooked sausages**: **74°C (165°F)**
These should be heated to this temperature when reheating or serving.

- **Ground poultry (such as turkey or chicken)**: **74°C (165°F)**
Always ensure the internal temperature reaches this level when cooking ground poultry products.

### 2. **Cooling Temperatures**

When cooling cooked food, it's important to cool it as quickly as possible to prevent bacteria growth. The general guideline for cooling food is:

- **Cool from 60°C to 20°C** (140°F to 68°F) within **2 hours**.
- Then, cool it further from 20°C to 4°C (68°F to 40°F) in the next **4 hours**.
- **Total cooling time** should not exceed **6 hours**.

**Quick Cooling Methods:**
- Use shallow pans to spread food out for faster cooling.
- Place food in an ice bath or blast chiller if available.
- Stir liquids frequently to release heat.

### 3. **Chiller (Refrigeration)**

Refrigerators (or **chillers**) are used to store perishable foods to slow bacterial growth. Proper temperature in chillers is essential for food safety.

- **Temperature Range**: **0°C to 5°C (32°F to 41°F)**
- This is the ideal range for chilling perishable items like dairy, meats, seafood, fresh fruits, and vegetables.
- Always store raw meat on the bottom shelves to prevent cross-contamination.

**Important Points:**
- Keep the refrigerator at or below **4°C (40°F)**.
- Store cooked food and raw food separately.
- Use a thermometer to monitor the temperature regularly.

### 4. **Freezer Temperatures**

Freezers are used to store frozen foods. Freezing food prevents the growth of bacteria but does not kill them, so it's essential to keep food at the right freezing temperature for preservation.

- **Temperature Range**: **-18°C to -22°C (0°F to -7.6°F)**
- Keep frozen foods at this temperature to maintain their quality and prevent freezer burn.
- Food can be safely stored in the freezer indefinitely at this temperature, but quality may deteriorate over time.

**Freezing Tips:**
- **Label foods** with dates before freezing to keep track of how long they’ve been stored.
- **Pack foods in airtight packaging** to prevent freezer burn.
- Thaw frozen foods **in the refrigerator** or in the microwave, not on the counter.

### 5. **Danger Zone**

The **danger zone** is the temperature range where harmful bacteria multiply most rapidly. It's important to keep foods out of this range as much as possible.

- **Danger Zone**: **4°C to 60°C (40°F to 140°F)**
- Bacteria grow exponentially in this temperature range. This is why it’s critical to avoid leaving food out at room temperature for extended periods.

**Critical Points**:
- **Keep hot foods hot** (above 60°C / 140°F) and **cold foods cold** (below 4°C / 40°F).
- Do not leave cooked food at room temperature for more than **2 hours** (or **1 hour** if the room temperature is above **32°C / 90°F**).
- **Reheat food** to **74°C (165°F)** before serving.

### 6. **Serving Temperatures**

When serving food, it should be kept at the correct temperature to ensure safety and quality:

- **Hot food** should be served at a minimum of **60°C (140°F)**.
- **Cold food** should be kept below **5°C (41°F)**.

### Summary of Temperature Guidelines:
| **Food Handling Stage** | **Recommended Temperature** |
|-----------------------------|-----------------------------------------|
| **Cooking** (Various foods) | 63°C to 75°C (145°F to 165°F) |
| **Cooling** | 20°C to 4°C (68°F to 40°F) in 6 hours |
| **Chiller (Refrigeration)** | 0°C to 5°C (32°F to 41°F) |
| **Freezer** | -18°C to -22°C (0°F to -7.6°F) |
| **Danger Zone** | 4°C to 60°C (40°F to 140°F) |
| **Serving** | Hot food: 60°C (140°F), Cold food: 5°C (41°F) |

By adhering to these temperatures, you ensure the safety, quality, and shelf life of food. It’s essential for kitchens, especially in high-end restaurants or hotels, to monitor and control these temperatures carefully to prevent foodborne illnesses and ensure a high standard of food quality.
