Question 1

What is the significance of German cockroaches (Blattella germanica) in food premises and how can they be identified?

Accepted Answer

They are small (12-15mm), light brown with two dark parallel stripes on the pronotum, nocturnal, carry multiple pathogens including Salmonella and E. coli, reproduce rapidly (producing 30-40 eggs per ootheca), and prefer warm, humid areas near food and water

Answer

German cockroaches are the most common cockroach species in UK food premises. They are distinguished from Oriental cockroaches by their smaller size, lighter colour, and two dark stripes on the pronotum (shield behind the head). They carry over 30 species of bacteria, 6 species of parasitic worms, and 7 other pathogens. Their rapid reproduction (each ootheca contains 30-40 eggs with a 28-day cycle) means infestations can grow exponentially. They prefer warm, humid environments near food sources — typically kitchens, behind equipment, and in wall voids.

Question 2

What proofing measures should be implemented to prevent pest entry into food premises?

Accepted Answer

Sealing gaps greater than 6mm around pipes and cables, fitting self-closing doors with brush strips, installing fly screens on opening windows, maintaining drains with intact covers, ensuring roof integrity, and sealing gaps around service entries

Answer

Proofing is the most important element of IPM. Mice can squeeze through gaps as small as 6mm, and rats through 12mm gaps. Key measures include: sealing gaps around pipes, cables, and service entries with appropriate materials (cement, metal mesh, expanding foam with wire wool); fitting self-closing doors with maximum 6mm gap beneath; installing fine mesh fly screens (1.2mm mesh) on opening windows and ventilation points; maintaining drains with intact covers; ensuring roof integrity; and fitting bird netting where needed.

Question 3

What should a pest control contract with an external provider include?

Accepted Answer

A detailed specification including visit frequency, pest species covered, monitoring methods, treatment protocols, bait station map, reporting requirements, emergency call-out response time, operatives' qualifications, insurance details, and compliance with British Pest Control Association standards

Answer

A comprehensive pest control contract should specify: scope (which pests, which areas), visit frequency (risk-based), monitoring equipment and methods, treatment protocols including pesticides to be used, bait station location maps, detailed written report format, KPIs and trend analysis, emergency response times (typically 24 hours), operatives' qualifications and training records, public liability insurance, compliance with BPCA/NPTA codes of practice, and COSHH documentation for all products used.

Question 4

How should a food safety supervisor respond to evidence of a cockroach infestation?

Accepted Answer

Immediately contact the pest control contractor for emergency treatment, segregate and inspect food stock for contamination, intensify cleaning of affected areas, investigate the source and harbourage points, review proofing measures, document all findings and actions, and consider whether product recall or disposal is necessary

Answer

A cockroach infestation requires immediate escalated response: emergency contact with pest control contractor, inspection and segregation of potentially contaminated stock, deep cleaning of affected areas (cockroach droppings and cast skins are allergens), identification of harbourage sites and entry points, review of all proofing measures, documentation for food safety records, assessment of product safety (disposal if contamination suspected), and review of the HACCP plan if the infestation suggests prerequisite programme failures.

Question 5

What are Electronic Fly Killers (EFKs) and what are the requirements for their placement in food premises?

Accepted Answer

UV light units that attract and kill flying insects, which must be positioned at entry points but away from food preparation areas, not above food or food surfaces, at the correct height (1.5-2m), serviced annually with UV tube replacement, and catch trays cleaned regularly

Answer

EFKs use UV light to attract flying insects to either an electrified grid (which can scatter insect fragments — not suitable near food) or a glue board (preferred in food areas as insects are contained). Placement rules: position near entry points to intercept incoming insects, never directly above food preparation/display areas (risk of contamination from fragments or falling insects), at 1.5-2m height for optimal attraction, away from competing light sources. UV tubes lose effectiveness over 8,000-12,000 hours and must be replaced annually. Catch trays or glue boards must be inspected and cleaned/replaced regularly.
