Safe Handling and Sanitation Practice
This domain tests the operational controls that keep food safe between receiving and service: temperature control, cross-contamination prevention, stock rotation, and cleaning and sanitising. Questions tend to be quantitative, asking for a temperature, a time limit or the correct order of steps.
Temperature control
The danger zone is roughly 5 °C to 60 °C. Keep cold food at or below 5 °C, frozen food at or below -18 °C, and hot food held for service at or above 60 °C. Cook poultry thoroughly, to at least 74 °C at the thickest part. Reheat food to 74 °C, once only, and never keep reheated food for a second reheating. Cool cooked food quickly: from 60 °C down to 21 °C within two hours, then to 5 °C or below within a further four hours. Thaw in the refrigerator, under running potable water, or in a microwave used immediately, never on the counter.
Cross-contamination
Store raw meat, poultry and fish below cooked and ready-to-eat food in the refrigerator, in covered containers. Use separate or colour-coded boards and utensils for raw and cooked items, and clean and sanitise them between tasks. Never use the same cloth for raw meat juices and surfaces that touch ready-to-eat food.
Stock rotation and records
First in, first out; date-code opened and prepared food; check deliveries for temperature, damage and labelling; keep temperature logs.
Cleaning and sanitising
Scrape or remove debris, wash with detergent and hot water, rinse, then apply sanitiser at the labelled concentration for the labelled contact time, and air dry. Test strips confirm concentration. Never mix cleaning chemicals.
Worked example
A caterer thaws 10 kg of chicken on the counter from morning until noon. The surface reaches the danger zone for hours while the centre stays frozen, so bacteria multiply before cooking even begins. The correct answer is refrigerator thawing overnight in a covered container on the bottom shelf, or controlled thawing under running potable water, followed by immediate cooking.
Traps that cost marks
- Partial cooking followed by cooling and finishing later.
- Re-freezing thawed meat, or re-freezing food that was previously frozen and thawed.
- Reheating more than once, or holding reheated food below 60 °C.
- Using a sanitiser stronger than the label specifies, which is unsafe and can taint food.
- Wiping a board with a damp cloth instead of washing, rinsing and sanitising it.
Food Safety Hazards
This domain tests whether you can recognise, classify and control hazards: biological, chemical and physical, plus allergens. Questions usually present a food, a practice or an incident and ask for the most likely hazard type, the probable source, or the control that matches. Precision in naming the hazard is where marks are won and lost.
Biological hazards
Bacteria include Salmonella (poultry, eggs), E. coli O157:H7 (undercooked beef, contaminated water), Staphylococcus aureus (hands, wounds, nose), Clostridium perfringens (stews and gravies cooled slowly), Bacillus cereus (reheated rice), Listeria (ready-to-eat chilled foods, unpasteurised dairy) and Vibrio (seafood). Viruses such as norovirus and hepatitis A come from infected handlers. Parasites include tapeworm and Giardia; moulds produce mycotoxins. Distinguish infection, where the organism grows in the gut, from intoxication, where a toxin was already formed in the food. Reheating kills Staphylococcus aureus and Bacillus cereus cells but not their toxins, which is why a reheated stew can still cause vomiting.
Chemical hazards
Aflatoxins in groundnuts, maize and their products; pesticide residues on vegetables; veterinary drug residues; heavy metals from worn cookware or poorly glazed pottery; cleaning and sanitising chemicals left by inadequate rinsing; histamine in spoiled scombroid fish; deliberate adulteration.
Physical hazards
Glass, metal fragments, stones, bone, hard plastic, hair, pests and packaging pieces. Controls are supplier checks, sieves and metal detection where applicable, and maintenance of equipment.
Allergens
Peanut, tree nuts, milk, egg, fish, crustaceans, soy, wheat and sesame must be known, labelled and separated to prevent cross-contact.
Worked example
A pot of groundnut soup simmers on the fire from morning until evening. Which hazard dominates? Mouldy groundnuts would be an aflatoxin risk checked at receiving, but the dominant process hazard is toxin production by Bacillus cereus or Clostridium perfringens while the soup sits in the danger zone. A full answer names the hazard type, the source and the control: rapid cooling or hot holding above 60 °C.
Traps that cost marks
- Assuming spoiled food always looks or smells bad. Most pathogens leave no trace.
- Treating allergens as a quality issue rather than a safety hazard.
- Blaming the last meal eaten in every outbreak without evidence.
- Confusing infection with intoxication, which changes whether reheating helps.
Product Quality Monitoring and Complaint/Alert Reporting
This domain tests what happens after food leaves the kitchen or the shelf: post-market monitoring, complaint handling, recalls and public alerts. Questions often give a scenario such as several customers falling ill, or a supplier reporting a contaminated batch, and ask what you do first and whom you notify.
Monitoring
FDA surveillance includes inspection, sampling and laboratory analysis, market surveillance, and review of consumer complaints and adverse event reports. Businesses run their own monitoring through temperature logs, supplier verification, shelf-life checks, in-house tasting panels and record review.
Handling a complaint, step by step
- Listen and record the facts: product name, batch or date code, where and when bought, date and time eaten, symptoms, number affected, contact details.
- Preserve the suspect food, its packaging and any leftovers; do not discard or destroy them.
- Assess internally and stop sale of the affected batch where risk is plausible.
- Report promptly to the FDA district office and cooperate with the investigation. Suspected foodborne illness is also reported through the health system, including the Ghana Health Service and the district assembly.
- Take corrective action, document it, and follow up with the complainant.
Recalls and traceability
Recalls are graded by health consequence: Class I for a serious health risk or death, Class II for temporary or reversible harm, Class III for minor or technical defects. Traceability one step back and one step forward is what makes a recall possible, and a mock recall tests whether records actually work. The FDA may issue a public alert or recall notice.
Worked example
Three customers report vomiting six hours after a catered party. The first actions are to record details, preserve leftover food and packaging, stop serving the implicated items, and contact the FDA while reviewing preparation and temperature records. Discarding the food because it looks spoiled destroys the evidence the investigation needs and is the wrong first move.
Traps that cost marks
- Throwing away the remaining food and packaging before investigators arrive.
- Waiting for more complaints before reporting, which delays the alert.
- Denying responsibility to the customer instead of documenting and escalating.
- Having no batch codes or supplier records, which makes withdrawal of a batch impossible.
- Treating a complaint as a public relations problem rather than a safety one.
