Worked Solution & Example Answer:On a ship at sea there is an outbreak of a disease affecting the human digestive system - HSC - SSCE Biology - Question 18 - 2009 - Paper 1
Step 1
Explain how cleanliness in food practices could assist in controlling this disease.
Answer
Maintaining cleanliness in food practices is crucial in controlling the outbreak. Ensuring that food is prepared in a clean environment helps to prevent the introduction of pathogens. Use of sanitized utensils and keeping food stored properly can minimize contamination. It is important to follow cooking guidelines that ensure food is cooked thoroughly to kill any harmful microorganisms.
Step 2
Explain how cleanliness in water could assist in controlling this disease.
Answer
Using clean, potable water is essential for preventing disease spread. Contaminated water can serve as a vehicle for pathogens, so treating water through filtration or boiling can eliminate harmful agents. Providing access to safe drinking water fosters healthy hydration practices and minimizes the risk of waterborne illnesses.
Step 3
Explain how personal hygiene practices could assist in controlling this disease.
Answer
Good personal hygiene practices are vital in preventing the spread of disease. Regular handwashing with soap and water, especially after using the restroom and before eating, significantly reduces the risk of transmission. Encouraging crew members to understand the importance of cleanliness can create a healthier environment on the ship.
