Minister of health is responsible for: - Correct Answers -Administration and enforcement
of the human pathogens and toxins act and regulations
Public health agency of canada - Correct Answers -Regulatory agency that
communicates and enforces the legislation
Purpose of legislation - Correct Answers -Establish a safety and security regime to

Risk group 4 - Correct Answers -High individual risk, high community risk
Risk group - Correct Answers -The classification of biological material based on its
inherent characteristics, including pathogenicity, virulence, risk of spread and availability
of effective prophylactic or therapeutic treatments, that describe the risk to the health of
individuals and the public as well as the health of animals and the animal population
