Key points

  • Follow the actual process-specific CCPs and controls, not a universal list of kitchen tasks.
  • Check delivery condition and substitutions, including allergens; pressure is not a reason to accept unsafe goods.
  • Keep the source’s chilling temperatures qualified by jurisdiction and food type; also prevent raw drips and storage contamination.
  • The outside colour does not replace the approved cooking standard and specified check.
  • Cool quickly and safely; reheating does not necessarily make food safe after a cooling failure.
  • Holding equipment maintains food already safely prepared; correct a failure by assessing the food, not only adjusting the unit.
  • Separate raw and ready-to-eat food and control allergen cross-contact; shared equipment can transfer risk.

Lesson guide

4.1 CCPs in everyday work

A critical control point controls a significant hazard at an essential stage of a particular food process. The example of cooking chicken illustrates why the food must meet a safe standard before service. A tidy room or completed sheet cannot substitute for that cooking control.

The module follows operational areas that may contain CCPs or other important controls. Their classification depends on the food and the business’s HACCP plan; not every delivery, storage or cleaning task is automatically a CCP. Know the procedure, limit and response for your assigned checks. Report a failed control and keep uncertain or unsafe food from service while the responsible person decides the appropriate action.

4.2 Delivery checks

Food should come from appropriate suppliers and arrive in suitable condition. Check packaging, dates, labelling and the required temperature or frozen condition under the delivery procedure. Look for swelling, damage, mould, pest contamination, warm chilled food or other acceptance failures rather than relying on the supplier’s reputation alone.

A substitute ingredient also needs checking. A changed burger bun may introduce milk or sesame, altering the allergen information used for orders and labels. Do not accept questionable goods because a driver is impatient or the kitchen is busy. Report the problem, reject food where required and retain suitable delivery and traceability information. Checked ingredients are part of controlling the whole process that follows.

4.3 Storage controls

The source identifies 8°C as the maximum for foods requiring chilling in England, Wales and Northern Ireland, while many businesses use a fridge target of 5°C for a safety margin. Keep that jurisdiction and food qualification attached: this is not presented as a universal Scottish rule or a substitute for the business’s more specific procedure.

Keep frozen food properly frozen and report softening, wet packaging or unusual large ice crystals for assessment. Cover, label and date food; separate raw food from ready-to-eat food, including storing raw food below it to prevent drips. A suitable fridge reading cannot compensate for raw meat leaking onto salad. Follow stock, storage and allergen controls as well as temperature checks.

4.4 Cooking checks

Cooking can be a CCP for foods such as poultry, minced meat, sausages, rolled joints and relevant raw egg dishes. A browned outside does not establish that the centre has met the business’s safe cooking standard. Use the approved method and specified check for the food and equipment.

Where probing is required, use a clean, suitable probe in the thickest part or centre as instructed and clean it between uses. Do not replace an approved time/temperature method with an invented visual test. If a result fails, do not serve; further cooking and a recheck may be appropriate where safe. If the food cannot be corrected safely or you are uncertain, stop and ask the responsible person.

4.5 Cooling and reheating

Cooked food intended for later use needs a safe cooling procedure. Suitable business methods may involve smaller portions, shallow trays, an ice bath or a blast chiller. A deep container of curry or rice left warm for hours can allow harmful bacteria to grow and some toxins to form.

Reheating is not a guaranteed rescue for unsafe cooling because some toxins may remain a hazard. Reheat thoroughly by the approved procedure rather than gently warming the outside. Failed checks require the appropriate safe correction or disposal decision; do not keep trying to save food when its earlier handling cannot be confirmed as safe. Follow the method, timing and record requirements the business has established for the actual batch.

4.6 Hot and cold holding

The source gives normally at least 63°C for hot holding and refers to 8°C for cold holding where temperature control is required. Apply these alongside the food, jurisdiction and business procedure qualifications given in the module, rather than inventing blanket exceptions or times.

Preheat hot-holding equipment and use it to keep already cooked or reheated food hot, not to cook cold food. Keep display food protected with appropriate covers, screens and utensils, and manage allergen separation. If the unit fails or a food check is below the standard, assess the food and time involved under the procedure. Turning up the equipment does not prove that food already affected is safe.

4.7 Cross-contamination and allergens

Raw food can contaminate ready-to-eat food through hands, boards, utensils, surfaces and drips. Prevent this with practical separation, handwashing and effective cleaning and disinfection. Food that will not be cooked again needs protection throughout preparation and service.

Allergen cross-contact also needs control. Tongs used for cheese can transfer milk to another order, while oil shared with battered fish can affect a supposed gluten-free chip order. Cooking does not remove these allergen risks. Use checked ingredient information, clean or separate equipment, clear labels and accurate order communication. Stop and report suspected contamination or uncertain suitability rather than serve food with an unsupported assurance.

In practice

Substitute burger buns

Source teaching example rewritten as a formative scenario; not a real reported incident

A supplier sends different buns from the usual brand.

Can the existing allergen list be assumed correct?

Check the current label or specification and report any difference before use or confirming customer suitability.

Substitutions can introduce different allergens such as milk or sesame.

Hot unit drops below its standard

Source teaching example rewritten as a formative scenario; not a real reported incident

The unit has been turned up, but food was held at a failed temperature.

Is the adjustment enough to release the food?

Assess affected food and exposure under the corrective procedure; do not serve if safety is uncertain.

An equipment setting does not undo the food’s previous conditions.

FAQs

Is every delivery or storage control a CCP?

No. These are operational controls whose CCP status depends on the actual process and HACCP plan. They remain important even when managed in another way.

Does a cold fridge prove salad is safe?

No. Raw drips, unclean equipment, poor dates or allergen cross-contact can still make food unsafe. Temperature is one control among several.

Can I simply increase the unit setting after a holding failure?

Correct the equipment, but also assess food already affected, including relevant time and temperature information. Follow the corrective procedure and do not serve uncertain food.

[0:00] Welcome to lesson 4.1, what a critical
[0:02] control point means.
[0:04] A critical control point, often called a
[0:07] CCP, is a step in the food process where
[0:09] control is essential to prevent, remove,
[0:12] or reduce a food safety hazard to a safe
[0:14] level.
[0:15] In simple terms, it is a point where
[0:17] something must be done correctly because
[0:19] if it fails, unsafe food could reach the
[0:22] customer.
[0:23] For example, cooking chicken may be a
[0:25] critical control point.
[0:27] If the chicken is not cooked properly,
[0:29] harmful bacteria may survive.
[0:32] Chilled storage may also be important
[0:34] because high-risk food can become unsafe
[0:36] if it is kept too warm.
[0:38] A critical control point is not just any
[0:40] normal task.
[0:42] It is a point where food safety depends
[0:44] on the control working properly.
[0:47] For example, keeping a kitchen tidy is
[0:49] important, but checking that cooked food
[0:51] has reached the correct safe standard
[0:53] may be critical because the customer
[0:54] could be harmed if it is wrong.
[0:57] At level two, you may not decide what
[0:59] the critical control points are, but you
[1:01] must understand and follow the controls
[1:03] in your workplace.
[1:05] If a procedure says to check a
[1:06] temperature, check it properly.
[1:09] If a limit is not met, report it and
[1:11] follow corrective action.
[1:13] Do not guess, ignore the issue, or serve
[1:15] food when safety is uncertain.
[1:18] The key message is a critical control
[1:20] point is a stage where food safety must
[1:22] be controlled.
[1:24] Staff must take these checks seriously
[1:26] because they protect customers from
[1:27] unsafe food.
[1:29] Welcome to lesson 4.2, delivery and
[1:32] supplier controls.
[1:34] Food safety controls start before food
[1:36] enters the kitchen.
[1:38] Delivery and supplier controls help make
[1:40] sure food arrives safely, from a
[1:42] suitable source, in good condition, and
[1:44] with the correct information.
[1:46] When food is delivered, staff may need
[1:48] to check the supplier, delivery note,
[1:50] packaging, dates, temperature, labels,
[1:53] and general condition of the food.
[1:55] For example, chilled food should arrive
[1:57] cold, frozen food should arrive frozen,
[2:00] and packaging should be clean, sealed,
[2:02] and undamaged.
[2:04] Food should not be accepted if packaging
[2:06] is leaking, badly damaged, dirty,
[2:08] swollen, moldy, contaminated, or showing
[2:11] signs of pests.
[2:13] Supplier control is also important.
[2:16] A business should use trusted suppliers
[2:18] and keep enough information to identify
[2:20] where food came from.
[2:22] This helps with traceability if there is
[2:24] a recall or food safety problem.
[2:27] Allergen information must also be
[2:28] checked.
[2:30] If a supplier sends a substitute
[2:31] product, the allergen information may
[2:33] change.
[2:35] A different bread, sauce, spice mix, or
[2:38] dessert may contain allergens that the
[2:39] usual product does not contain.
[2:42] For example, if the usual burger bun is
[2:44] replaced with one containing sesame or
[2:46] milk, the allergen information for the
[2:48] menu item may no longer be correct.
[2:51] At level two, your role is to check
[2:53] deliveries according to the workplace
[2:55] procedure, report problems, and never
[2:57] accept unsafe food just because the
[2:59] driver is waiting.
[3:01] The key message is delivery and supplier
[3:03] control stop unsafe or unsuitable food
[3:06] entering the business in the first
[3:07] place.
[3:09] Welcome to lesson 4.3, storage and
[3:11] temperature controls.
[3:13] Storage and temperature controls are
[3:15] important because food can become unsafe
[3:17] if it is stored in the wrong place, at
[3:19] the wrong temperature, or in a way that
[3:21] allows contamination.
[3:23] Chilled food that needs temperature
[3:24] control must be kept cold.
[3:27] In England, Wales, and Northern Ireland,
[3:29] cold food that needs temperature control
[3:31] must be kept at 8° C or below, and many
[3:34] businesses set fridges at 5° C or below
[3:37] to allow a safety margin.
[3:40] Frozen food should stay frozen solid.
[3:43] If frozen food is soft, wet, partly
[3:45] defrosted, or covered in large ice
[3:47] crystals, it may have been stored
[3:49] incorrectly and should be reported.
[3:51] Storage is not only about temperature.
[3:54] Food should also be covered, labelled
[3:56] when needed, used within date, and
[3:58] separated to prevent contamination.
[4:01] Raw meat, poultry, and fish should be
[4:03] stored below ready-to-eat food, so raw
[4:05] juices cannot drip onto food that will
[4:07] not be cooked again.
[4:09] For example, a fridge may be cold
[4:11] enough, but if raw chicken is stored
[4:13] above cooked meat, the cooked meat may
[4:15] become contaminated.
[4:17] High-risk foods such as cooked meat,
[4:19] dairy products, prepared salads,
[4:21] sandwiches, cooked rice, and desserts
[4:23] need careful storage because bacteria
[4:25] can grow if they are not controlled
[4:27] properly.
[4:28] At level two, your role is to follow
[4:30] fridge and freezer procedures, complete
[4:32] checks honestly, store food correctly,
[4:35] and report temperature problems
[4:36] immediately.
[4:38] The key message is safe storage means
[4:40] correct temperature, correct separation,
[4:42] correct labelling, and quick action when
[4:44] something is wrong.
[4:46] Welcome to lesson 4.4, cooking as a
[4:48] critical control point.
[4:51] Cooking is often a critical control
[4:53] point because proper cooking can kill
[4:54] harmful bacteria.
[4:56] This is especially important for food
[4:58] such as poultry, minced meat products,
[5:00] sausages, rolled joints, raw egg dishes,
[5:03] and foods made from raw ingredients.
[5:06] If these foods are undercooked, harmful
[5:08] bacteria may survive and cause food
[5:10] poisoning.
[5:12] Food may look browned on the outside,
[5:13] but still be undercooked in the middle,
[5:15] so staff should follow the business
[5:17] cooking procedure.
[5:19] In some workplaces, cooking may be
[5:21] checked using a probe thermometer.
[5:23] The probe should be clean, used
[5:25] correctly, placed into the thickest part
[5:27] or centre of the food, and cleaned
[5:29] between uses to prevent contamination.
[5:32] Other businesses may use approved
[5:34] cooking times, visual checks, and
[5:36] standard procedures, depending on the
[5:38] food and system.
[5:39] The important point is that staff must
[5:41] follow the business method and not
[5:43] guess.
[5:44] For For chicken should not be served
[5:46] just because the outside looks cooked.
[5:49] The inside must also be cooked safely
[5:51] according to the workplace procedure.
[5:54] If food does not meet the required
[5:55] cooking standard, the corrective action
[5:57] may be to continue cooking and check
[5:59] again.
[6:00] If safety cannot be confirmed, the food
[6:02] must not be served.
[6:05] At level two, your role is to cook food
[6:07] properly, follow instructions, complete
[6:09] records honestly where required, and
[6:11] report any cooking problems.
[6:13] The key message is cooking can make food
[6:15] safe, but only when it is done properly.
[6:19] Never serve food if you are unsure it
[6:20] has been cooked safely.
[6:22] Welcome to lesson 4.5, cooling and
[6:25] reheating controls.
[6:27] Cooling and reheating are important
[6:29] HACCP controls because bacteria can grow
[6:31] if food spends too long at unsafe
[6:33] temperatures.
[6:35] Cooked food that will be chilled and
[6:36] used later should be cooled as quickly
[6:38] and safely as possible before being
[6:40] placed into the fridge.
[6:42] Large deep containers cool slowly, so
[6:44] businesses may use shallow trays,
[6:46] smaller portions, ice baths, blast
[6:49] chillers, or another approved method.
[6:52] For example, a large pot of curry or
[6:54] rice left warm on the side for hours can
[6:56] stay in the danger zone too long.
[6:58] Bacteria may grow, and some bacteria can
[7:01] produce toxins that may not be destroyed
[7:03] by reheating.
[7:05] Reheating must also be controlled.
[7:08] Food should be reheated thoroughly
[7:09] according to the business procedure.
[7:12] It should not just be warmed slightly on
[7:13] the outside.
[7:15] For example, if soup, curry, or cooked
[7:17] meat is reheated, staff must make sure
[7:20] it is hot throughout before it is served
[7:22] or placed into hot holding.
[7:24] If reheated food does not meet the
[7:26] required standard, corrective action may
[7:28] be to continue heating and check again.
[7:31] If safety is uncertain, the food must
[7:33] not be served.
[7:35] At level two, your role is to follow
[7:37] cooling and reheating procedures, avoid
[7:39] leaving food standing around, record
[7:41] checks where required, and report
[7:43] anything that may not have been cooled
[7:44] or reheated safely.
[7:46] The key message is cooling and reheating
[7:49] are high-risk stages.
[7:51] Control time, control temperature, and
[7:53] never guess when food safety depends on
[7:55] it.
[7:57] Welcome to lesson 4.6, hot holding, cold
[8:00] holding, and display.
[8:02] Hot holding, cold holding, and food
[8:04] display are important controls because
[8:06] food may be kept ready for service for a
[8:08] period of time.
[8:10] Hot food should normally be held at 63°C
[8:13] or above.
[8:15] Hot holding equipment should be
[8:16] preheated before use, and food should
[8:18] already be properly cooked or reheated
[8:20] before it is placed inside.
[8:23] Hot holding equipment is designed to
[8:24] keep food hot.
[8:26] It should not be used to cook food from
[8:28] cold.
[8:29] Cold food should be kept at 8°C or below
[8:32] where temperature control is required.
[8:35] This may include chill displays,
[8:37] sandwich counters, salad bars, dessert
[8:39] displays, and grab-and-go fridges.
[8:42] Food on display also needs protection
[8:44] from contamination.
[8:46] Staff should use covers, clean utensils,
[8:49] sneeze screens where needed, separate
[8:51] serving equipment, and good allergen
[8:52] controls.
[8:54] For example, if cooked chicken is held
[8:56] in a hot cabinet and the temperature
[8:58] drops too low, bacteria may begin to
[9:00] grow if the food stays there too long.
[9:03] If sandwiches are displayed in a fridge
[9:05] that is too warm, they may also become
[9:07] unsafe.
[9:08] Display areas can also create
[9:10] cross-contamination risks if customers
[9:12] or staff use the wrong utensils, if
[9:15] foods touch, or if allergens transfer
[9:17] between products.
[9:19] At level two, your role is to check
[9:21] holding and display temperatures
[9:22] according to the procedure, keep food
[9:24] protected, use clean utensils, and
[9:26] report problems quickly.
[9:29] The key message is food on display still
[9:31] needs food safety control.
[9:33] Keep hot food hot, cold food cold, and
[9:36] all displayed food protected from
[9:37] contamination.
[9:39] Welcome to lesson 4.7, allergen and
[9:42] cross-contamination controls.
[9:45] Allergen and cross-contamination
[9:46] controls are important parts of HACCP
[9:48] because contamination can make food
[9:50] unsafe.
[9:51] Cross-contamination happens when harmful
[9:54] bacteria, allergens, chemicals, or
[9:56] physical hazards transfer from one food,
[9:59] surface, object, or person to another.
[10:02] One of the biggest risks is raw food
[10:04] contaminating ready-to-eat food.
[10:07] Ready-to-eat food will not be cooked
[10:08] again before serving, so any bacteria
[10:11] transferred onto it may reach the
[10:12] customer.
[10:14] For example, if raw chicken is prepared
[10:16] on a board and the same board is then
[10:18] used for salad without proper cleaning
[10:19] and disinfection, harmful bacteria may
[10:22] transfer onto the salad.
[10:24] Allergen cross-contact is also serious.
[10:27] If milk, nuts, sesame, egg, gluten, or
[10:30] another allergen gets into food by
[10:32] mistake, cooking will not remove the
[10:34] allergen.
[10:36] For example, using the same tongs for
[10:38] cheese and then for a dairy-free order
[10:40] may transfer milk.
[10:42] Using a shared fryer for battered
[10:43] products and chips may create gluten
[10:45] cross-contact.
[10:47] Controls may include separating raw and
[10:49] ready-to-eat foods, washing hands,
[10:52] cleaning and disinfecting surfaces,
[10:54] using clean utensils, storing food
[10:56] correctly, controlling allergens,
[10:58] checking labels, and communicating
[11:00] allergy requests clearly.
[11:02] At level two, your role is to follow
[11:04] these controls every time.
[11:07] If cross-contamination may have
[11:08] happened, do not ignore it.
[11:11] Report the issue and follow the business
[11:12] procedure.
[11:14] The key message is contamination can
[11:16] happen silently.
[11:18] HACCP controls help stop bacteria and
[11:20] allergens reaching food that should be
[11:22] safe for the customer.
