Sanitation & Disease Prevention Flashcards

Which of the following represents a 'conducive condition' a pest management professional should document during a sanitation inspection?

Answer: A gap under an exterior door greater than 1/4 inch

A gap larger than 1/4 inch under an exterior door is a conducive condition because it allows rodent and cockroach entry into the structure.

Salmonellosis outbreaks in food facilities are most frequently linked to which combination of factors?

Answer: Pest activity depositing pathogens on food contact surfaces combined with inadequate sanitation

Pests such as cockroaches and rodents introduce Salmonella onto food contact surfaces, and inadequate sanitation allows the pathogen to persist and multiply.

Under the FDA Food Safety Modernization Act (FSMA), pest control in registered food facilities is classified as a component of:

Answer: Good Manufacturing Practices (GMPs) and environmental monitoring

FSMA incorporates pest control under Good Manufacturing Practices, requiring facilities to implement measures that prevent pests from contaminating food or food contact surfaces.

Which of the following is the MOST effective long-term strategy to prevent stored grain insects like weevils from infesting a food warehouse?

Answer: Maintaining stock rotation (FIFO), cleaning storage areas thoroughly, and inspecting incoming shipments

First-in-first-out (FIFO) rotation prevents old stock from becoming infested, cleaning removes residual grain where insects breed, and inspecting incoming goods prevents introduction.

The presence of mud tubes on a foundation wall is a sanitation-relevant finding primarily because it indicates:

Answer: A moisture problem that is attracting termites and must be corrected alongside treatment

Mud tubes signal subterranean termite activity, which is often associated with excess soil moisture and wood-to-soil contact — conditions that must be corrected as part of an integrated management approach.

Which disease is transmitted by the black-legged tick (Ixodes scapularis) and is directly preventable through habitat modification and sanitation practices?

Answer: Lyme disease

Lyme disease, caused by Borrelia burgdorferi, is transmitted by Ixodes scapularis, and habitat modification (e.g., removing leaf litter, brush piles, and creating buffer zones) reduces tick populations.

Which of the following describes the MOST important sanitation consideration when managing a drain fly (Psychodidae) infestation in a commercial building?

Answer: Physically cleaning the organic gelatinous film from inside drain pipes where larvae develop

Drain fly larvae develop in the organic biofilm lining drain pipes; physically removing this film with a drain brush eliminates the breeding site and is the essential sanitation step.
