Three Vomiting Staff and a 180-Guest Event Tomorrow
On Friday at 9:00 p.m., three members of a 22-person catering crew report vomiting; two also have diarrhea. None has a fever. One, a prep cook, spent Wednesday evening at a family gathering where two relatives were later ill with identical symptoms. Another worked Friday's 6:00 a.m. to 12:00 p.m. shift prepping 40 lb of deli sandwiches, chicken salad and cut fruit for a Saturday event of 180 guests, began feeling nauseated at 11:00 a.m. but finished the shift and said nothing. At 9:30 p.m. the chef learns all of this and calls you. The event is at 2:00 p.m. tomorrow and the client has paid a deposit.
1. What is your immediate decision on the three staff, and how does the one who worked while symptomatic change your assessment?
Read the worked answer
Exclude all three from food handling and from any area with exposed food or clean equipment. The symptom profile - sudden vomiting with diarrhea, no fever, short duration - plus a household contact and a 12โ48 hour incubation window points strongly at norovirus, which has an extremely low infectious dose and is shed in vomit and stool. You do not need a lab result to act; the presentation plus the shared exposure is enough.
Return is not before 48 hours after symptoms resolve, and the person in charge should confirm it in person rather than accept a phone assurance.
The employee who worked while symptomatic is the decisive fact. He handled ready-to-eat chicken salad, sandwiches and cut fruit for four hours with active symptoms. Those foods will not be cooked again and cannot be washed clean; hand contact, droplets, and shared utensils are all plausible transfer routes. That converts a staffing problem into a probable contamination event on 40 lb of finished product.
2. What happens to the 40 lb of prepared food, and what is your recommendation on the Saturday event?
Read the worked answer
The food goes. All ready-to-eat items handled by the symptomatic worker - chicken salad, assembled sandwiches, cut fruit - should be discarded, not repurposed, not reheated, not 'used first.' Norovirus is not inactivated by normal cooking temperatures, and reheating does nothing about contamination already on the surface of the food.
Uncut, unpeeled produce from sealed cases and food that never entered his work zone can be kept if you can show the separation; if you cannot show it, treat the whole prep as affected.
On the event: the honest answer is that it depends on whether you can staff 180 guests with an unexposed crew and clean, uncontaminated product. If the answer is no, telling the client today is the correct commercial decision - a cancellation costs a deposit, an outbreak costs the business. Notify the regulatory authority per local requirement; most jurisdictions expect reporting of a suspected foodborne illness cluster involving food handlers. Do not promise the client a root cause before you have one.
3. Describe the cleaning, disinfection and return-to-work conditions you would set before the kitchen reopens.
Read the worked answer
Clean first, then disinfect - the order matters. Norovirus sits in organic material, and a disinfectant applied onto vomit or food residue is wasted.
- Close and segregate the prep area. Use disposable towels, bag and discard them, and clean from the highest surface down to the floor.
- Disinfect hard, non-porous food contact surfaces with a chlorine solution in the 1,000โ5,000 ppm range per label directions and contact time (CDC guidance for norovirus), then rinse food contact surfaces with potable water before use. Alcohol wipes are not adequate.
- Replace wiping cloths, discard the sanitizer buckets, and change mop water; the mop and bucket are a classic spreader.
- Delegate one trained person to symptom surveillance: no one on the crew with vomiting or diarrhea in the last 72 hours, and 48 hours clear before anyone returns.
- Re-emphasize no bare-hand contact with ready-to-eat food and handwashing after toilet use, before gloving, and after any contact with a contaminated surface.
Document everything - the regulator will ask what you did and when, and the answer needs to be a record, not a recollection.
