WSQ Pest Management — Questions and Answers
Question 1: What are the common pests found in Singapore food establishments?
- Only cockroaches
- Cockroaches, rats/mice, flies, ants, lizards, and stored product insects (weevils, beetles) (Correct answer)
- Only rats
- Pests are not a problem in Singapore
Correct answer: Cockroaches, rats/mice, flies, ants, lizards, and stored product insects (weevils, beetles)
Singapore's tropical climate creates ideal conditions for pests. Common food premises pests include German cockroaches, American cockroaches, rats, mice, house flies, fruit flies, ants, and stored product insects.
Question 2: What is 'Integrated Pest Management' (IPM) in food safety?
- Using maximum pesticides
- A comprehensive approach combining prevention (denying food, water, shelter), monitoring, and targeted treatment to control pests with minimal chemical use (Correct answer)
- Killing all insects in the area
- Hiring a pest control company only
Correct answer: A comprehensive approach combining prevention (denying food, water, shelter), monitoring, and targeted treatment to control pests with minimal chemical use
IPM uses multiple strategies: preventing pest entry (sealing gaps), removing attractions (food, water, shelter), monitoring with traps, and using targeted chemical treatments only when necessary.
Question 3: What are the signs of a cockroach infestation in a food establishment?
- Only seeing live cockroaches
- Live or dead cockroaches, droppings (dark specks), egg cases (oothecae), musty odour, and smear marks along walls and corners (Correct answer)
- Only a bad smell
- There are no visible signs of cockroaches
Correct answer: Live or dead cockroaches, droppings (dark specks), egg cases (oothecae), musty odour, and smear marks along walls and corners
Cockroach signs include: live or dead specimens, droppings (like ground pepper), egg cases, shed skins, musty odour, and brown smear marks along their regular paths. Finding these requires corrective action.
Question 4: How can a food establishment prevent pest entry in Singapore?
- Leave doors open for ventilation
- Seal gaps around pipes, install door sweeps, use air curtains at entrances, screen windows, maintain proper drainage, and inspect deliveries for pests (Correct answer)
- Only use insecticide spray
- Pest prevention is impossible in tropical climates
Correct answer: Seal gaps around pipes, install door sweeps, use air curtains at entrances, screen windows, maintain proper drainage, and inspect deliveries for pests
Physical exclusion is the first line of defence: seal all entry points (gaps, cracks, pipe penetrations), install door closers and sweeps, use air curtains, screen openings, and inspect incoming goods.
Question 5: What attracts pests to food establishments?
- Only food left on counters
- Food sources (spills, crumbs, uncovered waste), water sources (leaks, condensation), and shelter (dark corners, gaps, clutter, warm equipment areas) (Correct answer)
- Only bright lights
- Pests are attracted randomly
Correct answer: Food sources (spills, crumbs, uncovered waste), water sources (leaks, condensation), and shelter (dark corners, gaps, clutter, warm equipment areas)
Pests need three things: food, water, and shelter. Eliminating any of these through good housekeeping, fixing leaks, proper food storage, and removing clutter makes your premises less attractive to pests.
Question 6: What should a food handler do if they find evidence of pest activity during food preparation?
- Continue working and report later
- Stop food preparation in the affected area, discard any potentially contaminated food, clean and sanitise the area, and report to the supervisor immediately (Correct answer)
- Spray insecticide on the food area
- Ignore minor pest signs
Correct answer: Stop food preparation in the affected area, discard any potentially contaminated food, clean and sanitise the area, and report to the supervisor immediately
Finding pest activity requires immediate action: stop work, assess contamination, discard affected food, clean and sanitise, report to management, and arrange for professional pest control inspection.
