Module 6: Temperature control

Control food temperatures and time across storage, cooking, cooling, display and delivery and act promptly when a check reveals a failure.

Records your study progress, not an assessment result or certificate.

Key points

  • Control time and temperature at every stage; cooked chicken left out may still look normal while becoming unsafe.
  • The source scopes general chilled-food 8°C rules to England, Wales and Northern Ireland and gives 5°C as a fridge safety-margin setting.
  • Around -18°C is described as a freezer target; keep food frozen and report possible defrosting, not a universal new legal rule.
  • Follow suitable cooking checks, reheat throughout and use the approved rapid-cooling method instead of guessing.
  • Preheated hot-holding equipment maintains already cooked or reheated food; it is not a cooker for cold food.
  • Maintain the required controls while awaiting collection and during delivery, including packaging and allergen order accuracy.

Lesson guide

6.1 Why time and temperature matter

Temperature control limits opportunities for harmful bacterial growth and supports suitable cooking. Higher-risk examples include cooked meats, poultry, fish, dairy, cooked rice and pasta, sauces, gravy, salads, sandwiches and desserts. Their normal appearance is not evidence that growth has not occurred.

Use controls across delivery, storage, preparation, cooking, reheating, cooling, display, takeaway waiting and delivery. Keep chilled food cold and hot food suitably hot and avoid unnecessary standing at room temperature. Time and temperature work together rather than being separate isolated checks.

The source cooked-chicken example leaves food on a worktop during a busy shift before using it in wraps. Bacteria may have had time to grow even if the food still looks fine. The relevant history and procedure matter, not a visual approval at the final serving stage.

A check protects customers only if staff act on a failure. Report warm fridges, food out too long or hot food below its holding control promptly and follow corrective instructions. The ending links prevention from cooking and storage through to the customer, not merely writing numbers in a log.

6.2 Fridges, freezers and displays

The source explicitly scopes the general requirement to keep chilled food needing temperature control at or below 8°C to England, Wales and Northern Ireland. Many businesses set fridges around 5°C or below to provide a margin when doors are opened frequently. Do not recast that setting as a universal UK legal limit.

Freezers must maintain the food appropriately frozen. The module describes around -18°C as a common target and warnings such as softened or wet food, partial defrosting or large ice crystals. Report concerns and follow the process rather than automatically assuming an unusual appearance proves a precise earlier temperature.

Check chilled and hot displays according to the business system. A sandwich unit can be full and attractive while too warm to maintain control. Customers cannot see the temperature risk, so actual checks and records are important during service.

Allow cold air to circulate rather than overloading equipment, keep doors closed where practical, cover and label food and store protected raw items below ready-to-eat food. The equipment name does not establish safety: temperature, arrangement and prompt response to problems need to work together.

6.3 Cooking, reheating and cooling

Cooking is particularly important for poultry, minced products, sausages, rolled joints, raw-egg dishes and other foods made from raw ingredients. Follow the appropriate business procedure, recipe, manufacturer’s directions and temperature-checking method; this source section does not provide a new numeric cooking combination.

Reheat properly so food is steaming hot throughout rather than slightly warm at the outside. Use the required checks and approved process. This teaching should be read alongside the earlier source warning that reheating does not universally reverse toxins created by unsafe storage.

Cooked food for later use needs suitable quick, safe cooling before chilled storage. Large deep containers can leave the centre warm for too long. Smaller portions, shallow trays or another approved method help the system handle the amount prepared.

A large pot of curry left warm on the side for hours illustrates the growth opportunity before chilling. Follow the safe process rather than guessing from the outside or relying on eventual refrigeration. The ending combines thorough cooking, suitable reheating and quick safe cooling as working controls.

6.4 Holding, packaging and delivery

The recording gives 63°C or above as the general hot-holding control and discusses chilled displays under the relevant 8°C arrangement. Follow the applicable business and jurisdiction controls for the actual food and service. Food should not be left out longer than the permitted procedure.

Preheat suitable hot-holding equipment and load food that has already been properly cooked or reheated. Hot cabinets and bain-maries are intended to maintain heat, not cook cold food. A holding stage cannot replace the required initial cooking or reheating process.

Pack and transport orders through suitable temperature-control arrangements using clean, fit bags, boxes and vehicles. In the early-takeaway example, a long wait for collection can cause loss of control before the journey starts. Follow the delay procedure and check whether the food remains safe.

Packaging protects from contamination, keeps the correct order together and helps prevent allergen or delivery mix-ups. Pass information and the correct item through packing and handover. The food-safety responsibility continues beyond the kitchen door until the food is served or received.

In practice

An attractive warm sandwich display

Source teaching example rewritten; illustrative, not a real incident report

The sandwich display looks full but its check is above the required control.

Does presentation make the check less important?

Report the actual failure and apply the food-assessment and equipment procedure.

Customers cannot see the bacterial growth opportunity created by poor temperature control.

A takeaway order waits too long

Source teaching example rewritten; illustrative, not a real incident report

An order prepared early has a long delay before collection.

Does safe cooking earlier prove the later order is safe?

Follow the delay and temperature procedure and assess the food before supply.

Control can be lost during waiting and transport after cooking.

FAQs

Is temperature control only recording numbers?

No. Check accurately and report and act on warm equipment, excessive time out or holding failures.

Is -18°C presented as a new universal law?

No. The source describes a common freezer target. Keep the food appropriately frozen and follow the actual product and equipment procedure.

Does this module state a numeric cooking combination?

No. It directs staff to the suitable procedure, recipe, manufacturer and checking system rather than supplying an invented new limit.

Can a hot cabinet replace cooking?

No. Load food already properly cooked or reheated and use suitable preheated equipment to maintain hot holding.

Does waiting for collection need control?

Yes. Long delays can lose control before the food leaves. Follow the delay procedure and check safety before supply.

[0:00] Welcome to lesson 6.1, why temperature
[0:02] control matters.
[0:04] Temperature control is one of the main
[0:06] ways food businesses prevent harmful
[0:08] bacteria from growing to unsafe levels.
[0:11] Some foods need extra control because
[0:13] they can support bacterial growth.
[0:16] These include cooked meat, poultry,
[0:18] fish, dairy products, cooked rice,
[0:21] cooked pasta, sauces, gravy, prepared
[0:24] salads, sandwiches, desserts, and other
[0:26] ready-to-eat foods.
[0:28] The risk is that food may look, smell,
[0:30] and taste normal even when bacteria have
[0:32] multiplied.
[0:34] This means food handlers cannot rely
[0:36] only on appearance.
[0:38] Time and temperature must be controlled
[0:40] properly.
[0:41] Temperature control applies at every
[0:43] stage: delivery, storage, preparation,
[0:46] cooking, reheating, cooling, display,
[0:49] takeaway, and delivery.
[0:51] Chilled food should be kept cold.
[0:54] Hot food should be kept hot.
[0:56] Food should not be left standing around
[0:58] at room temperature for longer than
[1:00] necessary.
[1:01] For example, if cooked chicken is left
[1:03] on a worktop during a busy lunch shift
[1:05] and later used in wraps, bacteria may
[1:08] have had time to grow.
[1:10] The chicken may still look fine, but it
[1:12] may no longer be safe.
[1:14] As a refresher, remember that
[1:16] temperature control is not just about
[1:17] checking numbers.
[1:19] It is about acting when something is
[1:21] wrong.
[1:22] If a fridge is too warm, if food has
[1:24] been left out too long, or if hot food
[1:27] has dropped below the safe holding
[1:28] temperature, report it straight away.
[1:31] The key message is simple. Temperature
[1:33] control protects food by slowing
[1:35] bacterial growth, killing bacteria
[1:37] during cooking, and keeping food safe
[1:39] until it reaches the customer.
[1:41] Welcome to lesson 6.2, fridge, freezer,
[1:44] and display temperatures.
[1:47] Fridges, freezers, and display units are
[1:49] important food safety controls, but they
[1:51] only work if they are used and checked
[1:53] properly.
[1:54] In England, Wales, and Northern Ireland,
[1:57] chilled food that needs temperature
[1:58] control must be kept at 8° C or below.
[2:02] Many businesses set fridges at 5° C or
[2:05] below to give a safety margin,
[2:07] especially when doors are opened often
[2:09] during busy service.
[2:11] food.gov.uk,
[2:12] freezers should keep food frozen solid.
[2:15] Many businesses aim for around -18° C.
[2:19] If
[2:20] If frozen food is soft, wet, partly
[2:22] defrosted, or covered in large ice
[2:24] crystals, it may have been stored
[2:26] incorrectly and should be reported.
[2:29] Display units also need careful control.
[2:32] Chilled display food, such as
[2:34] sandwiches, salads, desserts, and cooked
[2:36] meats should stay cold enough during
[2:38] service.
[2:40] Hot displays should keep hot food at
[2:41] safe holding temperatures.
[2:44] For example, a sandwich display may look
[2:46] full and well presented, but if the unit
[2:48] is too warm, bacteria may grow in
[2:50] high-risk foods.
[2:52] Customers cannot see this risk, so staff
[2:55] must check and record temperatures
[2:56] according to the business procedure.
[2:59] Good storage also matters.
[3:01] Do not overload fridges because cold air
[3:03] needs to circulate.
[3:05] Keep doors closed when possible.
[3:08] Keep food covered and labelled.
[3:10] Store raw food below ready-to-eat food
[3:13] to prevent dripping and
[3:14] cross-contamination.
[3:16] As a refresher, remember a fridge,
[3:18] freezer, or display unit is only safe
[3:20] when the temperature is controlled, food
[3:22] is stored correctly, and problems are
[3:24] reported quickly.
[3:26] Welcome to lesson 6.3, cooking,
[3:29] reheating, and cooling.
[3:31] Cooking, reheating, and cooling are key
[3:33] stages where food can either be made
[3:35] safe or become unsafe.
[3:38] Cooking food properly helps kill harmful
[3:40] bacteria.
[3:42] This is especially important for food
[3:43] such as poultry, minced meat products,
[3:46] sausages, rolled joints, raw egg dishes,
[3:48] and foods made from raw ingredients.
[3:51] Always follow the business procedure,
[3:53] recipe, manufacturer's instructions, or
[3:56] temperature checking system.
[3:58] Reheating must be done properly.
[4:01] Food should be reheated until it is
[4:02] steaming hot throughout.
[4:04] It should not just be warmed slightly on
[4:06] the outside.
[4:08] The FSA explains that reheating food
[4:10] until it is steaming hot throughout is
[4:11] important to kill harmful bacteria that
[4:13] may have grown since the food was
[4:15] cooked.
[4:16] food.gov.uk
[4:18] Cooling is also important.
[4:21] Cooked food that will be stored and used
[4:22] later should be cooled as quickly and
[4:24] safely as possible before being placed
[4:26] in the fridge.
[4:27] Large deep containers cool slowly, so
[4:30] food may need to be divided into smaller
[4:32] portions, placed in shallow trays, or
[4:34] cooled using the business approved
[4:36] method.
[4:37] For example, a large pot of curry left
[4:39] warm on the side for hours can stay in
[4:41] the danger zone too long.
[4:43] Bacteria may grow before the food is
[4:46] chilled.
[4:47] As a refresher, remember: Cook
[4:49] thoroughly, reheat until steaming hot
[4:51] throughout, cool food quickly and
[4:53] safely, and never guess when food safety
[4:55] depends on temperature.
[4:57] Welcome to lesson 6.4, hot holding, cold
[5:00] holding, and delivery.
[5:02] Hot holding, cold holding, and delivery
[5:04] are used when food is kept ready for
[5:06] service or transported to the customer.
[5:09] These stages still need proper
[5:11] temperature control.
[5:13] Hot food should generally be held at
[5:15] 63°C
[5:16] or above.
[5:18] Hot holding equipment should be
[5:19] preheated before use, and food should
[5:21] already be properly cooked or reheated
[5:23] before being placed inside.
[5:26] Hot cabinets and bain-maries are
[5:27] designed to hold food hot, not to cook
[5:29] food from cold.
[5:31] Cold food should normally be kept at 8°C
[5:34] or below.
[5:36] This includes chilled displays, salad
[5:38] bars, dessert counters, and sandwich
[5:40] displays.
[5:41] Cold food should not be left out for
[5:43] longer than allowed by the business
[5:45] procedure.
[5:46] Food can also become unsafe during
[5:48] delivery.
[5:49] Hot food should be packed quickly and
[5:51] kept hot where required.
[5:53] Cold food should be kept cold,
[5:55] especially ready-to-eat food such as
[5:57] salads, desserts, sandwiches, and cooked
[6:00] meats.
[6:01] Delivery bags, boxes, and vehicles
[6:03] should be clean, suitable, and in good
[6:05] condition.
[6:07] For example, if a takeaway order is
[6:08] prepared early and left waiting too long
[6:11] before collection, the food may lose
[6:13] temperature control before it even
[6:14] reaches the customer.
[6:16] If there is a long delay, staff should
[6:18] follow the business procedure and check
[6:20] whether the food is still safe.
[6:23] Packaging also matters.
[6:25] It should protect food from
[6:26] contamination, keep the correct order
[6:28] together, and prevent allergen or
[6:30] delivery mix-ups.
[6:32] As a refresher, remember food safety
[6:34] does not end at the kitchen door.
[6:37] Hot holding, cold holding, and delivery
[6:39] must all protect food until it is served
[6:41] or received by the customer.
