In Gwladys Caspars' quick guide, "don't touch it" refers to biohazards in which Risk Group?

In the context of biocontainment and laboratory safety, "don't touch it" refers to biohazards classified in Risk Group 2. This group includes organisms that are associated with human disease but are unlikely to be a serious hazard to laboratory workers, the community, or the environment. While these pathogens can cause diseases that are treatable and might not pose a significant risk when handled properly, they still require caution. The guidance of "don't touch it" serves as a reminder that working with these organisms still necessitates the implementation of specific safety measures to avoid exposure and ensure biosecurity.

Risk Group 2 includes pathogens such as certain strains of bacteria and viruses that can be transmitted through direct contact or exposure to contaminated surfaces. Though the risks might be lower than those associated with higher risk groups, the potential for infection and the necessity for best practices in handling materials is crucial.
