The Flow of Food: An Overview
The flow of food encompasses every step a food product takes within a food service establishment, from the moment it is ordered until it is served to the customer. The primary goal at every step is to prevent foodborne illnesses by controlling biological, chemical, and physical hazards. A typical food flow sequence includes:
- Purchasing: Sourcing ingredients from approved, reputable suppliers.
- Receiving: Accepting and inspecting incoming food shipments.
- Storing: Placing food in designated areas to maintain quality and safety.
- Preparing: Thawing, washing, cutting, and portioning ingredients.
- Cooking: Heating food to its required internal temperature.
- Holding: Keeping food at a safe temperature until served.
- Cooling: Rapidly chilling cooked food for storage.
- Reheating: Bringing held food back up to a safe temperature.
- Serving: Delivering the finished product to the customer.
The Crucial First Stage: Receiving Food
The receiving stage is the first line of defense in protecting your operation from contaminated or unsafe food. By implementing a strict receiving protocol, a food service manager ensures that all incoming products meet the highest standards of safety and quality. This process is more than just accepting a delivery; it is a meticulous inspection process that involves checking for several key criteria.
Inspecting Food for Quality and Safety
When a delivery arrives, it is critical that a trained staff member is on hand to inspect the shipment immediately. This initial inspection must cover all aspects of the product and its packaging to identify any potential risks. Here are the key areas to check:
- Packaging Integrity: Check for torn, damaged, or stained boxes that could indicate tampering or pest damage. Reject cans that are dented, bulging, or have compromised seals.
- Temperature of TCS Foods: Time and Temperature Control for Safety (TCS) foods, which require strict temperature regulation, must be checked with a calibrated thermometer upon arrival. The 2017 FDA Food Code specifies that chilled TCS foods should be received at 41°F (5°C) or lower, and frozen foods must be frozen solid. Hot foods must be received at 135°F (60°C) or higher.
- Signs of Pests: Inspect packages for any evidence of pest activity, such as gnaw marks, droppings, or insects. Reject the entire delivery if any signs are found.
- Expiration Dates: Verify that all items are well within their 'Use by' or expiration date. This ensures proper stock rotation and prevents the use of spoiled products.
- Sensory Evaluation: Use sight, smell, and touch to assess the quality of food. For example, reject slimy, sticky, or dry meat or poultry. Discard any food with an abnormal or unpleasant odor or unusual color.
- Approved Suppliers: The delivery should only come from a reputable and approved supplier. Unapproved or homemade foods should never be accepted, as their source cannot be verified.
Comparison of Receiving Protocols: Small vs. Large Operations
| Feature | Small Operation Protocol | Large Operation Protocol |
|---|---|---|
| Inspection Team | Often a single trained manager or chef. | Dedicated receiving team with multiple inspectors. |
| Equipment | Simple, hand-held probe thermometers and visual inspection. | Advanced digital thermometers, data logging systems, and receiving docks. |
| Paperwork | Manual recording of delivery dates, temperatures, and condition on a simple checklist. | Integrated supply chain software for digital tracking and record-keeping. |
| Frequency | As deliveries arrive, potentially from multiple local suppliers. | Scheduled deliveries from a few key vendors, with strict time slots. |
| Corrective Action | Immediate rejection of non-compliant items and communication with the supplier. | Automated rejection process and vendor performance tracking for accountability. |
Beyond Receiving: A Look at the Next Steps
Once food has been safely received, the next steps in the flow of food are critical to maintaining safety standards.
Storing Food Safely
Proper storage is essential to prevent contamination and bacterial growth. The First-In, First-Out (FIFO) method is a standard practice that ensures older inventory is used before new stock. All food items should be labeled with their delivery date. In storage areas:
- Store raw products below cooked or ready-to-eat foods to prevent cross-contamination.
- Keep refrigerators at 41°F (5°C) or below and freezers at 0°F (-18°C) or lower.
- Store food off the floor and away from walls to allow for cleaning and air circulation.
Preparing for a Safe Kitchen
Preparation involves handling food before cooking. At this stage, preventing cross-contamination is paramount. This can be achieved by using separate cutting boards and utensils for raw meat and produce. Employees should practice excellent personal hygiene, including frequent hand washing.
Conclusion: The Foundation of Food Safety
The receiving stage is more than a simple transaction; it is a critical control point for any food service operation. By conducting a thorough and consistent inspection of all incoming food products, establishments can build a strong foundation for a comprehensive food safety system. From verifying temperature logs to checking for damaged packaging, diligent receiving practices prevent potential hazards from ever entering the kitchen. This foundational step protects not only the quality of the food but also the health and safety of the consumer, setting a positive tone for the rest of the food flow process. For further guidelines on managing critical control points, consult resources like the FDA's information on HACCP principles.

Frequently Asked Questions
Q: What are the main stages of the flow of food? A: The main stages include purchasing, receiving, storing, preparing, cooking, holding, cooling, reheating, and serving.
Q: Why is receiving considered the most important stage? A: The receiving stage is the first opportunity to ensure that ingredients meet safety standards, as food that arrives compromised cannot be made safe later in the process.
Q: What are Time and Temperature Control for Safety (TCS) foods? A: TCS foods are those that are most susceptible to bacterial growth and require strict temperature controls for safety, such as meat, dairy, and cut produce.
Q: How do you properly check the temperature of received food? A: Use a calibrated probe thermometer to check the temperature of items. For packaged foods, place the thermometer between two packages to get an accurate reading.
Q: What is FIFO and why is it important during storage? A: FIFO stands for First-In, First-Out, a stock rotation method that ensures items with the earliest use-by dates are used before those with later dates, minimizing spoilage and waste.
Q: How can I tell if food has been time-temperature abused? A: Indicators include receiving frozen food that is not solid, chilled food that is above 41°F (5°C), or packaged food with visible signs of temperature fluctuations like frost,.
Q: What should I do if a delivery is deemed unsafe during receiving? A: Immediately reject the entire shipment from the supplier. Clearly document the reason for the refusal and follow up with the supplier to ensure future deliveries meet your standards.
