True or False: There are published listings of risk groups for human pathogens available worldwide.

The correct understanding is that there are indeed published listings of risk groups for human pathogens available worldwide. Different organizations and institutions, including the World Health Organization (WHO), the Centers for Disease Control and Prevention (CDC), and various national health agencies, maintain and update classifications of pathogens based on their potential to cause harm to humans and their modes of transmission.

These risk group classifications, often referred to as biosafety levels (BSL), are important for informing laboratory practices, containment measures, and public health policies to protect both laboratory workers and the general population. The existence of these listings reflects a recognized need for standardized information regarding pathogens and their associated risks, facilitating appropriate safety measures across different countries and settings. In summary, the statement about the availability of published listings is accurate, making the answer true.
