Food-Borne Illness and a Burn on a School Picnic
A private school takes 62 Class IX students and 6 teachers to a farmhouse near Sohna for an annual picnic. Lunch is prepared at the school kitchen at 6:30 am: chicken mayonnaise sandwiches, paneer rolls and cut fruit. The food travels in ordinary cartons in the boot of a bus, is kept in a room without air-conditioning, and is served at 1:30 pm. By 4:00 pm, nine students complain of stomach cramps, two have vomited, and one has fainted. A teacher gives the fainted student water and asks the others to rest under a tree. Meanwhile, a student accidentally tips a flask of hot tea onto another student's forearm; the skin is red and blistering. The farmhouse has a first-aid box with antiseptic, cotton, bandages and paracetamol, and the nearest primary health centre is 9 km away. The bus driver is available.
1. Set out immediate first aid and triage for the two situations. Explain the priority order.

Priority is the fainted student: check response, breathing and pulse; if breathing, place in the recovery position, loosen clothing, turn the head to one side, and do not pour water into the mouth. Call 108 or the primary health centre immediately and send a teacher with the bus driver to meet the ambulance. For the nine with cramps, do not induce vomiting; give small sips of ORS only if fully conscious; keep them resting and separate from well students; record time of onset and what each ate. For the burn, cool the forearm under running water for 20 minutes, remove jewellery or loose clothing not stuck to the skin, cover with a clean non-fluffy cloth or sterile dressing, and do not apply ice, butter, toothpaste or cotton wool; do not burst the blister. Transport the burned student with the same ambulance if possible, or to the health centre after cooling. Paracetamol should not be given without medical advice because it can mask symptoms. The teacher's instinct to give water to an unconscious child was unsafe.
2. Who should be informed and what records and samples must be preserved? Explain why each matters.

Inform the principal immediately, then the parents or guardians of the nine ill students and the burned student, with facts only and no diagnosis. Inform the nearest primary health centre and the district health/food safety authority because this is a suspected food-borne outbreak; the school's insurer and the farmhouse manager should also be told. Preserve: leftover sandwiches, paneer rolls and cut fruit in their original cartons, sealed and labelled with time; any vomit or stool samples in clean containers if medically advised; the menu, cooking time, transport and serving time; the attendance list and a timeline of who ate what. Do not discard the food or clean the serving area until samples are taken. Records matter for treatment, because the doctor needs the suspected food; for the outbreak investigation; for insurance claims; and for legal protection. A written incident register with staff statements should be completed the same day, and parents should receive a follow-up call the next morning.
3. Identify three failures in food handling and propose corrections for future trips, including temperature control and menu choice.
Read the worked answer
Three failures: (1) high-risk menu - chicken mayonnaise held at 35–40°C for seven hours is a classic danger-zone risk; mayonnaise-based fillings should not be packed for a summer picnic. (2) No cold chain - ordinary cartons in a bus boot and a non-air-conditioned room cannot keep food below 5°C or above 60°C. (3) Long holding time - food cooked at 6:30 am and served at 1:30 pm exceeds safe holding without temperature control. Corrections: choose shelf-stable foods such as vegetable pulao, lemon rice, sealed curd, whole fruit and packaged juice, or use insulated boxes with ice packs and a thermometer; serve within two hours of removing from cold storage; cut fruit on site with clean hands and safe water; keep hand sanitiser and clean serving tongs; check food-handler health. A simple rule for the next trip: if the food cannot be kept cold, do not serve a creamy chicken or paneer item. Also carry ORS and a written emergency plan with the health centre number.
