Rodent and cockroach findings in a bakery
A 60 m² bakery in Sham Shui Po produces 400 loaves and 1,200 buns daily. During a routine inspection, an EHO finds 12 rodent droppings behind two 25 kg flour bags stacked against the wall, a 15 mm gap under the rear door, and one juvenile cockroach in a glue board near the mop sink. The grease trap is overflowing, and staff use the same cloth to wipe benches and the floor. The pest control contractor visits every four weeks; the last report, dated three weeks earlier, states 'no activity'. The manager says the contractor is 'responsible for pests' and asks whether the bakery can keep operating while the contractor deals with it. Flour scoops are stored loosely on a shelf.

Rank first the rodent droppings in direct contact with flour storage, because they indicate pathogens, foreign matter and contamination of a ready-to-use ingredient. Second is the overflowing grease trap and shared cloth, which create cross-contamination and attract pests. Third is the 15 mm door gap, which allows rodent entry. Fourth is the juvenile cockroach, which suggests a breeding population near the mop sink. The pest contractor is not a defence: the licensee must provide a pest-proof structure, sanitation and food protection. A 'no activity' report three weeks earlier is unreliable when fresh droppings and a nymph are found; the contractor's monitoring may be insensitive, or the report may not have been verified by staff.
2. What immediate actions should be taken, and can the bakery continue operating?

Do not simply continue as before. Isolate the affected storage area; discard flour bags contaminated by droppings or with gnawed packaging; clean and disinfect shelves, floor and walls. Fix the door gap, targeting 6 mm or less, with a metal kick plate and self-closing door. Store flour off the floor and away from walls, and keep scoops in a clean container. Empty and clean the grease trap, remove refuse, and treat cockroach harbourages with gel bait and crack-and-crevice work. Introduce colour-coded cloths and a clean-then-disinfect schedule. The bakery may continue only if food areas are pest-free and product is protected; otherwise suspend affected production. Recheck before resuming full output.
3. What records and monitoring should the EHO require to verify that pest control is effective?
Read the worked answer
Require the contractor's service reports, bait map, device locations, findings, trend data, technician details and corrective recommendations. The bakery should keep daily or weekly checks of glue boards, fresh droppings, smear marks, gnaw marks and sightings, with a named person signing off. Set a threshold for escalation, such as any rodent sighting or fresh droppings triggering an immediate investigation. Verify after two weeks and again after proofing works. The manager must not delegate legal responsibility to the contractor; he should review and sign the reports and ensure structural and cleaning defects are corrected. If activity persists, require a more frequent service and a written action plan.
