How are Category A Infectious substances listed on the List of Dangerous Goods?

• A. Infectious substance, affecting humans
• B. Infectious substance, affecting animals
• C. Category A infectious substances
• D. Infectious substance, Category A

Answer: (D)

On the List of Dangerous Goods, Category A infectious substances are identified with the exact wording “Infectious substance, Category A.” This phrasing is the standardized shipping name used to mark substances that require the strictest packaging, labeling, and handling because they can cause life-threatening or permanent disease. The other options describe host scope (humans or animals) or rearrange the wording, but they aren’t the official listing used to designate Category A. Using “Infectious substance, Category A” clearly signals the highest level of regulatory controls for these substances.
