Question 1

What is Laboratory Animal Allergy (LAA) and what are its symptoms?

Accepted Answer

IgE-mediated response to animal proteins causing rhinitis, conjunctivitis, skin reactions, and potentially asthma

Answer

LAA is an IgE-mediated hypersensitivity to proteins in animal urine, dander, and saliva, with symptoms from rhinitis to life-threatening asthma.

Question 2

What is the purpose of pre-employment health screening for animal workers?

Accepted Answer

To establish baseline health data, identify pre-existing risks, and develop individualized protection plans

Answer

Pre-employment screening establishes baseline data for future comparison, identifies conditions increasing risk, and enables personalized risk mitigation.

Question 3

What are the primary zoonotic disease risks from laboratory rodents?

Accepted Answer

LCMV, hantavirus, dermatophytosis, rat bite fever, and allergic sensitization

Answer

Risks include LCMV (mice), hantavirus (wild rodents), rat bite fever (from bites), dermatophytosis (ringworm), and allergic sensitization.

Question 4

What is the proper response after an animal bite?

Accepted Answer

Wash thoroughly, apply first aid, report to supervisor, seek medical evaluation per institutional procedures

Answer

Response: wash with soap and water for 5+ minutes, apply antiseptic, report to supervisor, complete incident report, seek medical evaluation.

Question 5

What engineering controls help reduce allergen exposure?

Accepted Answer

IVC systems, ventilated cage changing stations, HEPA-filtered room supply, and proper ventilation rates

Answer

Engineering controls are most effective: IVC systems contain allergens, ventilated stations provide HEPA protection, and proper room ventilation dilutes airborne allergens.
