The sick cook, the blocked sink, and the gloves
At a 40-seat café, the only handwashing sink, at the back, is blocked by stacked cases of canned tomatoes, so staff have been rinsing their hands at the produce-prep sink beside the sandwich station. The dishwasher is waiting for a part, so dishes are being done in the three-compartment sink. On Tuesday morning the manager learns three things before the 11:30 lunch rush of 60 covers: (a) Dana, the sandwich-station cook, went home Monday at 2:00 p.m. with vomiting and diarrhea and says she has felt fine since 6:00 a.m. Tuesday; (b) Marco has a small cut on his thumb and his bandage keeps coming loose; (c) a new hire has worn the same pair of gloves for her entire 4-hour shift and has been washing the gloves instead of her hands.
1. Dana wants to work the sandwich station at 11:30 Tuesday. What is your decision and why?
Read the worked answer
No - exclude her from food handling, and not just from the sandwich station. A food handler who has had vomiting or diarrhea is excluded until 48 hours after symptoms resolve. Symptoms stopped at 6:00 a.m. Tuesday, so the earliest return is 6:00 a.m. Thursday.
Why 48 hours rather than '24 hours after the last episode': norovirus is shed in vomit and stool for days after a person feels well, and the infectious dose is tiny - a few particles on a fingertip. Norovirus is the most common cause of foodborne illness in Canada, and the classic vehicle is a handler who returned too early and contaminated a ready-to-eat food that is never cooked again.
The sandwich station is the worst possible assignment: bread, lettuce, cheese, sliced meat, all handled and served cold. The manager covers the station or calls in a replacement. 'She feels fine' is not evidence, and gloves do not change the decision - gloved hands transfer norovirus just as efficiently as bare ones.
2. The hand sink is blocked and staff are using the produce sink. What do you do before 11:30, and why is the produce sink unacceptable?
Read the worked answer
The hand sink must be cleared and stocked before any food handling starts, and the produce sink cannot substitute.
A handwashing sink has to be accessible at all times, supplied with hot and cold running water, soap, and single-use paper towels, and used for nothing except handwashing. A sink that also rinses lettuce - or takes mop water - is not a handwashing sink under any interpretation. Staff 'rinsing' at it are not washing: no soap lather, no 20 seconds, no proper drying, and the tap handles are recontaminated on the way out.
Order of operations this morning:
- Move the cases of tomatoes to dry-storage shelving (never the floor), not to another sink or the aisle.
- Confirm soap, paper towels, and warm water at the back sink; post a sign.
- If the sink cannot be made usable before 11:30, service does not start. Delaying or closing is cheaper than an outbreak.
Longer term, the café needs a layout where the hand sink is never a storage shelf, ideally a second sink near the front.
3. Evaluate Marco's bandaged thumb and the new hire's glove habit. What corrections are needed?
Read the worked answer
Marco's cut. A small cut can be worked with only if it is covered by a waterproof bandage and, on the hand, a single-use glove over it - and the glove must be changed whenever it tears or the bandage slips. A loose, repeatedly failing bandage is itself a physical hazard and a contamination route. If the cut cannot be kept dry and covered, or if it shows infection (redness, pus, tenderness), he is excluded from food handling until it heals.
The new hire's gloves. The gloves are the problem, not the solution. Gloves are single-use and are changed whenever you would wash your hands: before starting, after raw meat, after touching your face or phone, after the washroom, after garbage, and at minimum every 4 hours. Washing gloved hands is not handwashing - the glove traps moisture and bacteria against the skin and the wrist seam leaks.
The rule to teach: wash hands, then don gloves. Gloves never replace the 20-second wash. That is three separate corrections to make before 11:30.
