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
Cleanliness in food practices involves ensuring that all food served on the ship is stored, prepared, and served in a sanitized environment. This includes washing hands before handling food, cooking food thoroughly, and avoiding cross-contamination. By implementing strict food safety protocols, the risk of foodborne pathogens entering the digestive systems of the crew and passengers is minimized, thereby reducing the spread of the disease.
Step 2
Explain how cleanliness in water could assist in controlling this disease.
Answer
Maintaining cleanliness in water sources on the ship is crucial. This involves regularly testing and treating the water supply to eliminate harmful bacteria and viruses. Ensuring that drinking water is properly filtered and stored can help prevent the consumption of contaminated water, which is a common vector for diseases affecting the digestive system.
Step 3
Explain how personal hygiene practices could assist in controlling this disease.
Answer
Personal hygiene practices, such as frequent hand washing with soap, are essential in preventing disease transmission. Crew members should be educated on the importance of hygiene before meals and after using the restroom. Providing adequate sanitary facilities, like clean restrooms and handwashing stations, can further promote good hygiene and help control the spread of the outbreak.
