From Truck to Table: Ensuring Hygiene in Your Supply Chain

See what it takes to keep food fresh and clean, from truck to table.

While diners don’t have to think about the journey their food has taken to reach their plates, we – as professional Chefs – do.

With food items being passed from one location to another and handled by many pairs of hands along the way, the potential for contamination and spoilage is high. That’s why it’s key that you know what happens to food as it’s delivered to your location – and learn how you can help to ensure that this process is a smooth one that guarantees the freshness and cleanliness of your ingredients.



Selecting Reliable Suppliers

  • Good reputation: Choose suppliers with good past records.
  • Quantity and quality: Personally inspect the quality of a supplier’s food to ensure freshness, then decide if they can provide the quantities you need on a daily or weekly basis.
  • Reliability: Your supplier should have no problems providing you with on-time deliveries of fresh inventory.
  • Testing: When working with a new supplier, always order samples or small quantities to test them out before committing to larger contracts.
  • Asking questions: Your supplier’s hygiene measures are just as important as yours – find out how they are implementing stricter practices.


  • Always check for cross-contamination (e.g. raw meat mixed with vegetables).
  • Ensure product specifications are met: If food is supposed to be frozen, ensure it is not thawed or defrosted.
  • Always inspect food packaging for damage and avoid keeping supplies at room temperature for too long.
  • Check the date of expiry on all products and return any items that are expired.
  • All food MUST be checked on delivery. In addition to the check against the original order, an assessment of food quality must be made.

Reject unsatisfactory stock! 

  • High-risk foods should be delivered in refrigerated vehicles and should be rejected if they are above the specified delivery temperature, normally this will be 5 ºC or below and will be detailed on the packaging.
  • Frozen foods should be rejected if above –12 ºC. Check for signs of thawing such as fluid or frozen liquid in the carton. Items such as frozen peas should be individually separated not frozen in one ice mass. This indicates temperature fluctuations and it will impair final quality.
  • Reject any foods that have punctured, torn or slashed packaging.
  • Reject any foods that are abnormal in odour, colour or texture.
  • Reject foods which have expired date codes or cannot be used within the date code period. All packaged, perishable foods must be date coded. NEVER USE FOOD PAST THEIR DATE CODES.

Storing and Issuing

  • Remove carton boxes and do not place food items on the floor (to prevent the breeding of cockroaches and rodents).
  • Observe a First-in, First-out method of stock allocation to maintain the freshness of your ingredients.
  • Prevent cross-contamination by storing ready-to-eat food above raw food, and at correct temperatures.
  • Cover both raw and cooked food at all times to prevent exposure to oxygen.
  • Cool cooked food before refrigerating to prevent moisture from building up.



  • Once frozen food is thawed, never re-freeze it.
  • Once the food is removed from the fridge, it must be cooked within 2 hours.
  • Thaw frozen meat/seafood in a plastic container under running water to prevent exposing food to room temperature.
  • Use separate chopping boards for raw/cooked foods.

Cooking and Holding

  • Cook food thoroughly at its required minimum temperature.
  • Avoid keeping food exposed at room temperature.
  • Do not combine freshly prepared food with food that is being held (and could have been contaminated).
  • During reheating of held food, ensure that it reaches the required minimum temperature for at least 15 seconds.
  • Use food covers for ready-to-eat food to prevent exposure to oxygen.

Plating and Serving

  • Serving staff must maintain good hygiene while serving food. For example, holding cups by the base/handle and not by the mouth, and using a tray if possible.
  • Serving staff must be aware of their personal hygiene.
  • Only use clean, sanitised utensils.
  • Clean regularly: Ensure tables are wiped, floors are swept and mopped, and rubbish is emptied.

Managing Leftovers

Touched leftovers:

  • Throw these away immediately.

Untouched leftovers:

  • Reheat to the required minimum temperature.
  • Only reheat once and consume within 12 hours.
  • To prevent wastage, untouched leftovers can be used as ingredients in other dishes provided that:
  • Dry food must be reused within 2 days.
  • Wet food must be reused within 1 day.

Product Tracing and Recalls

  • If a product is recalled, immediately remove all food from service, kitchen and storage.
  • Backtracking of activities: Track and record the serving of food, as well as how it was produced, stored and received. 
  • Assign someone to respond to customer complaints: Record information from customers such as their name, contact, day and time they dined at your establishment.
