A Cook With Bloody Diarrhoea, a School Kitchen and Pressure to Conceal Illness
A cook named Musa at a school feeding kitchen in Kano develops fever, headache and diarrhoea. He visits a patent medicine vendor, takes an antidiarrhoeal and paracetamol, and returns to work the next day because the school has 600 pupils and no relief cook. He continues to prepare rice and beans, tastes food with the same spoon, and uses the toilet, washing hands only with water. On day 4 his stool is bloody and he has a temperature of 38.8°C. The supervisor says that if Musa reports it, the school will close and Musa will lose pay. Three other kitchen staff had similar illness last month, and one later had yellow eyes and dark urine. The school has no food handler health records and no written reporting procedure.
1. Should Musa be excluded from food handling? For how long and on what criteria? Explain the legal and public health reasoning.

Musa should be excluded from food handling immediately. He has fever, diarrhoea and now bloody stool - a picture that can fit Shigella, invasive E. coli, Salmonella or typhoid, all of which can be spread by food and by hands. The legal and public health logic is that a food handler who is symptomatic is a known source; exclusion protects 600 pupils and staff. The employer's fear of closure or lost pay does not override that duty.
He should be referred for medical assessment and stool testing, and the case should be reported to the local government environmental health officer or state health authority under the applicable public health and food hygiene rules. Exclusion normally continues until at least 48 hours after symptoms resolve; for typhoid or Shigella, the medical officer may require negative stool samples and clearance before return. He must not prepare or taste food while symptomatic. The supervisor should arrange relief cover and not pressure him to conceal illness.
2. What should the supervisor do about the kitchen, the food Musa has handled, and the earlier illnesses among staff?

Supervisor actions: (1) remove Musa from the kitchen at once; (2) arrange a relief cook or a limited menu so the school can operate safely; (3) send him for diagnosis and notify the health authority; (4) stop bare-hand tasting and the shared spoon; (5) clean and sanitise the kitchen, utensils and toilet area; (6) review whether other staff have symptoms - the earlier illness and jaundice suggest a possible hepatitis A or other cluster and should be investigated; (7) keep a written record of the exclusion and the corrective actions.
Food already prepared by Musa that day should be assessed: if it was handled after his symptoms and is ready-to-eat, discard it; do not rely on reheating to fix hand contamination. The school should also explain to parents and staff that reporting illness is expected, not punished.
3. What health-reporting and return-to-work system should the school adopt to prevent this situation recurring?
Read the worked answer
Build a simple system: a pre-employment health questionnaire and food handler medical certificate; a named person responsible for health reporting; a written rule that any fever, diarrhoea, vomiting, jaundice, sore throat with fever, or infected cut must be reported before starting work; a relief pool so absence does not close the kitchen; and a log of exclusions and return-to-work clearances. Train staff that reporting is a duty, not a betrayal, and that pay or shift pressure must not be used to keep a sick handler at work.
Also enforce handwashing with soap and running water after the toilet, before food handling and after waste handling; provide a clean toilet and handwash point; supervise tasting with a clean spoon; and keep contact details for the local government environmental health officer. Periodic review of illness reports can catch clusters early - the earlier jaundice case should have triggered a review.
