Bloodborne pathogens may be present in which of the following?

• A. Blood, tissue, or organs
• B. Air
• C. Water
• D. Soil

Answer: (A)

Bloodborne pathogens are organisms that can be carried in human blood and certain body materials. They may be present in blood, tissue, or organs from an infected person, and transmission can occur when these materials contact someone who has a break in the skin or mucous membranes. Air, water, or soil are not the typical avenues for spreading bloodborne pathogens in workplace exposure; they are more associated with other routes of transmission, such as airborne or environmental sources. That makes blood, tissue, or organs the relevant materials where these pathogens may be found, which is why this option is correct.
