Which organizations publish regulations for the transport of dangerous goods and/or animals that may contain hazardous materials?

The correct answer highlights the relevant authorities responsible for setting regulations concerning the transport of dangerous goods and animals that may contain hazardous materials. The US Department of Transportation's Pipeline and Hazardous Materials Safety Administration (PHMSA) is specifically tasked with regulating the safe transport of hazardous materials in the United States. This includes ensuring that all aspects of transport, from packaging to labeling, meet stringent safety standards to protect public health and the environment.

The International Civil Aviation Organization (ICAO) works similarly on an international level, establishing regulations that airline operators must follow when transporting dangerous goods. This includes specific guidelines for the safe transport of animals that may be classified as hazardous materials.

Together, these organizations create comprehensive guidelines that address both domestic and international transportation of potentially dangerous items, thereby ensuring safety during transit and reducing the risk associated with hazardous materials.

The other options may mention important organizations, but they focus on different aspects of public health or veterinary practices rather than specifically addressing the transportation of dangerous goods or hazardous materials.
