Final answer:
To prevent food from being contaminated by parasites, it is important to wash hands properly, avoid cross-contamination, and cook food to the correct temperature. All of these safety measures are essential for maintaining food safety, hence the correct answer is: all of the above.
Step-by-step explanation:
To prevent parasites from contaminating food, one should implement a variety of safety measures:
- Ensuring food handlers wash their hands properly before and after handling or preparing food, and before eating to minimize the introduction of pathogens.
- Avoid cross-contamination by keeping raw foods, particularly meats, separate from ready-to-eat foods and by using separate utensils and cutting boards for different types of food.
- Cook food to the correct temperature to ensure that any harmful bacteria are killed. Food must reach an internal temperature of at least 74 degrees C (165 degrees F), and using a cooking thermometer can help verify this.
So, the correct answer is d. all of the above, as each of these practices play a critical role in preventing food contamination and ensuring food safety.
