Which concept focuses on preventing disease by labeling, controlling, and monitoring the spread of harmful organisms?

• A. Pathogen
• B. Water Quality Monitoring
• C. HACCP
• D. Bio-security

Answer: (D)

Bio-security concentrates on preventing disease by labeling, controlling, and monitoring the spread of harmful organisms. It involves actions to keep pathogens from entering a facility or farm and to limit their movement if they do appear, such as controlling who and what can move in and out, implementing sanitation and disinfection practices, using quarantine for new or sick stock, and clearly labeling biohazard risks to guide safe handling and response. Ongoing surveillance and reporting help catch outbreaks early so they can be contained. The term pathogen refers to the disease-causing organism itself, not the prevention system. Water quality monitoring focuses on assessing water safety, not the broader prevention and management of disease spread. HACCP is a food-safety framework aimed at identifying and controlling hazards in production and processing, rather than a general program for preventing disease spread through labeling and movement controls.
