In the area of occupational health and safety, what does the acronym LAA stand for?

• A. Laboratory animal allergy
• B. Laboratory animal asthma
• C. Least amount available
• D. Local animal area

Answer: (A)

Laboratory Animal Allergy is an immune reaction to proteins from laboratory animals—things like dander, urine, saliva, and serum—that workers can encounter in animal facilities. This exposure can trigger allergic symptoms such as sneezing, nasal congestion, itchy or watery eyes, skin irritation, and in some people, can contribute to asthma symptoms. The term describes an allergy to animal proteins, not asthma itself, though asthma-like symptoms can occur in sensitized individuals. The other phrases don’t represent a recognized occupational term for this context. Prevention and control focus on reducing exposure through proper ventilation and containment, careful handling and cleaning practices, personal protective equipment, and medical surveillance for workers.
