Which item is NOT high‑risk?

• A. Cytotoxic medicines
• B. Vaccines
• C. Oil-based vaccines
• D. Glutaraldehyde disinfectants

Answer: (B)

Handling and stock safety in a veterinary setting hinges on the level of hazard a substance poses to staff during routine use. High‑risk items are those with significant potential to cause harm if mishandled, such as cytotoxic medicines, which can damage cells and have serious health effects with exposure, and caustic disinfectants like glutaraldehyde, which can burn skin, eyes, and airways and require strict ventilation and containment. Vaccines, while they require proper storage and safe administration, do not present the same occupational hazards to handlers under normal procedures; they’re designed to be given to animals and are managed with standard biosafety practices. Oil‑based vaccines are still vaccines and carry no greater handling risk to staff than other vaccines. So, vaccines are not considered high‑risk in this context.
