7/1 Principles of Food Safety
Key Concepts
The 7/1 Principles of Food Safety are essential guidelines that ensure the safety and quality of food products. These principles focus on preventing contamination, maintaining hygiene, and ensuring proper handling and storage of food. Understanding and applying these principles is crucial for Registered Nutritionists to ensure the safety of their clients and the public.
1. Clean
The "Clean" principle emphasizes the importance of maintaining cleanliness in all aspects of food preparation. This includes washing hands, cleaning surfaces, and sanitizing equipment to prevent the spread of harmful bacteria and contaminants.
Example: Before handling food, a Registered Nutritionist should wash their hands with soap and water for at least 20 seconds. Similarly, cutting boards and utensils should be washed with hot, soapy water and sanitized to avoid cross-contamination.
2. Separate
The "Separate" principle involves keeping raw and cooked foods apart to prevent cross-contamination. This includes using different cutting boards, utensils, and storage containers for raw and cooked foods.
Example: When preparing a meal, a Registered Nutritionist should use one cutting board for raw meat and another for vegetables. Additionally, raw meat should be stored on the bottom shelf of the refrigerator to prevent juices from dripping onto other foods.
3. Cook
The "Cook" principle focuses on cooking food to the appropriate temperature to kill harmful bacteria. This involves using a food thermometer to ensure that meat, poultry, and eggs are cooked to a safe internal temperature.
Example: A Registered Nutritionist should use a food thermometer to check that chicken breasts reach an internal temperature of 165°F (74°C) before serving. This ensures that any harmful bacteria present are destroyed.
4. Chill
The "Chill" principle emphasizes the importance of keeping food at safe temperatures to prevent the growth of bacteria. This includes refrigerating perishable foods promptly and keeping the refrigerator set to 40°F (4°C) or below.
Example: After preparing a meal, a Registered Nutritionist should refrigerate leftovers within two hours to prevent bacterial growth. Additionally, they should ensure that the refrigerator is set to the correct temperature to maintain food safety.
5. Use Safe Water and Raw Materials
The "Use Safe Water and Raw Materials" principle involves ensuring that all ingredients used in food preparation are safe and of high quality. This includes using clean water, fresh produce, and properly stored raw materials.
Example: A Registered Nutritionist should use bottled or filtered water for cooking and drinking if the tap water is not safe. They should also inspect fresh produce for signs of spoilage before using it in recipes.
6. Keep Food out of the Danger Zone
The "Keep Food out of the Danger Zone" principle refers to avoiding the temperature range where bacteria grow most rapidly, which is between 40°F and 140°F (4°C and 60°C). This involves minimizing the time food spends in this temperature range.
Example: During a meal preparation, a Registered Nutritionist should avoid leaving food out at room temperature for more than two hours. If the temperature is above 90°F (32°C), food should not be left out for more than one hour.
7. Educate and Train
The "Educate and Train" principle involves ensuring that all individuals involved in food preparation are properly trained in food safety practices. This includes providing regular training sessions and updates on food safety guidelines.
Example: A Registered Nutritionist should conduct regular food safety training sessions for kitchen staff, covering topics such as handwashing, proper food storage, and cooking temperatures. This ensures that everyone is aware of and follows food safety protocols.
Supplementary Tool: Food Safety Plan
A Food Safety Plan is a written document that outlines the specific steps and procedures to ensure food safety in a food service operation. This plan includes hazard analysis, critical control points, and monitoring procedures.
Example: A Registered Nutritionist working in a food service facility should develop a Food Safety Plan that includes a hazard analysis of potential risks, such as cross-contamination and improper cooking temperatures. The plan should also outline the steps to mitigate these risks and the procedures for monitoring compliance.
