1In Nigeria, who is legally required to conduct the medical examination that produces a valid food handler's test report?
A.Any pharmacy staff member
B.A registered medical practitioner at an approved facility
C.The food business owner
D.A NAFDAC marketing officer
Explanation: Under NAFDAC food hygiene guidance, persons handling food must hold a valid and satisfactory food handlers' test report issued following examination by a registered medical practitioner at an approved medical facility, confirming the handler is free from communicable disease.
2Which laboratory test commonly included in the Nigerian food handler medical screen is used to detect evidence of typhoid (Salmonella Typhi) exposure?
A.Widal test
B.Pregnancy test
C.Blood glucose test
D.Cholesterol panel
Explanation: The Widal test is the serological test commonly used in Nigerian food handler screening to detect antibodies suggesting typhoid (Salmonella Typhi) exposure. Stool culture is also used to identify carriers who could contaminate food.
3Why is a stool examination part of the food handler medical screen in Nigeria?
A.To measure the handler's daily fibre intake
B.To detect intestinal pathogens and carrier states that could contaminate food
C.To confirm the handler's blood type
D.To check vitamin D levels
Explanation: Stool examination (microscopy and culture) detects intestinal pathogens such as Salmonella, Shigella and parasites, including asymptomatic carriers, who could shed organisms onto food via faecal-oral transmission if they handle food.
4A food handler develops vomiting and diarrhoea overnight. What is the correct action before the next shift?
A.Report the illness and stay away from food handling until cleared
B.Take an antidiarrhoeal and report to work as normal
C.Work but avoid touching only cooked food
D.Wear two pairs of gloves and continue
Explanation: A handler with vomiting or diarrhoea must report the illness to their supervisor and be excluded from food handling until symptom-free (commonly at least 48 hours after symptoms stop) to prevent spreading pathogens such as Norovirus or Salmonella.
5What is the single most effective routine action a food handler can take to prevent transmission of foodborne pathogens?
A.Wearing a hairnet
B.Frequent and proper handwashing
C.Spraying air freshener in the kitchen
D.Wearing jewellery for identification
Explanation: Frequent, thorough handwashing with soap and clean running water is the single most effective measure to prevent faecal-oral and cross-contamination transmission of pathogens between hands, surfaces and food.
6Approximately how long should a food handler scrub their hands with soap during proper handwashing?
A.At least 20 seconds
B.About 2 seconds
C.Exactly 5 minutes
D.No fixed time is needed
Explanation: Effective handwashing requires scrubbing all surfaces of the hands with soap for at least 20 seconds, followed by rinsing under clean running water and drying with a single-use towel or air dryer.
7Which of the following is a moment when a food handler must always wash their hands?
A.Only at the start of the day
B.After using the toilet and before handling food
C.Only when hands look visibly dirty
D.Once per four-hour shift
Explanation: Hands must be washed after using the toilet and before handling food, as well as after touching raw food, waste, the face or hair, and after any task that could contaminate the hands. Visible dirt is not a reliable guide to contamination.
8A food handler has a small cut on a finger. What is the correct practice?
A.Leave it open so it dries faster
B.Cover it with a clean waterproof (preferably brightly coloured) dressing and a glove
C.Lick the cut to clean it
D.Ignore it because it is small
Explanation: Cuts and wounds must be fully covered with a clean, waterproof dressing (brightly coloured so it is visible if it falls into food) and, where appropriate, a glove, to prevent wound bacteria such as Staphylococcus aureus contaminating food.
9Why should food handlers remove rings, watches and bracelets before handling food?
A.They reduce dexterity only
B.They can harbour bacteria and may fall into food as a physical hazard
C.They are forbidden by tax law
D.They interfere with refrigerator magnets
Explanation: Jewellery traps dirt and bacteria that are hard to wash away and can also become a physical hazard if a stone or item falls into food, so it should be removed before food handling.
10A handler frequently coughs and sneezes near an open food preparation area. What is the recommended practice?
A.Sneeze directly over the food to clear the airway quickly
B.Turn away, cover the mouth/nose with a tissue or elbow, then wash hands
C.Hold the breath while plating food
D.Wear sunglasses to reduce the spread
Explanation: Coughing or sneezing can spray respiratory pathogens onto food. The handler should turn away from food, cover the mouth and nose with a tissue or the elbow, discard the tissue, and wash hands before resuming work.

About the Nigeria Food Handler Certificate Exam

The NAFDAC-aligned food handler certificate confirms that a person working with food in Nigeria understands food hygiene and is medically fit, being free from communicable diseases such as typhoid and tuberculosis. It combines a food hygiene knowledge assessment with a medical fitness examination (commonly including stool, Widal, Hepatitis B and chest X-ray screening), and certificates are typically renewed about every six months.

Assessment

Food hygiene knowledge assessment (typically multiple-choice) combined with a medical fitness examination at an accredited facility. Exact format and length vary by training provider and state.

Time Limit

Varies by provider; most food hygiene knowledge tests take roughly 30-60 minutes.

Passing Score

No single national pass mark is published; providers commonly require around 70-80% on the hygiene test, and the medical screen must confirm the handler is free from communicable disease.

Exam Fee

Varies by accredited facility and training provider; the medical test (stool, Widal, Hepatitis B, chest X-ray) and certificate fees are set locally and change periodically.
