Which foodborne illness is caused by a parasite?

The correct answer is trichinella, which is caused by a parasite known as Trichinella spiralis. This parasitic infection is predominantly associated with the consumption of undercooked or raw meat, particularly pork, and can lead to a condition known as trichinosis.

Understanding the distinction between pathogens is crucial in food safety. In contrast, salmonellosis is caused by bacteria, specifically Salmonella, which can be found in a variety of sources including poultry and eggs. Hepatitis A is a viral infection spread through contaminated food and water, often linked to improper sanitation practices. Staphylococcus aureus is another bacterial pathogen, commonly associated with improperly stored or handled foods that harbor the bacteria, leading to food poisoning.

Recognizing the specific causative agents of foodborne illnesses is vital for implementing effective preventive measures in food safety management systems, such as HACCP.
