What is the classification of a package containing suspected Brucella abortus culture that is being transferred from a veterinary clinic to the state veterinary laboratory?

• A. Category A substance
• B. Category B substance
• C. Non-infectious substance
• D. Exempt

Answer: (A)

The main concept here is risk-based classification for infectious substances in transport. A culture containing suspected Brucella abortus is a live infectious material that can cause serious disease, so it falls into Category A. This category covers the most dangerous infectious substances and requires the strictest packaging, labeling, and documentation. Category B would apply to less hazardous infectious substances, such as certain diagnostic materials with lower risk. Non-infectious and exempt do not fit because the culture is infectious and not eligible for exemption from dangerous goods regulations. Therefore, the proper classification is Category A.
