What are common diseases transmitted by contaminated food?

The correct response highlights specific pathogens known to cause foodborne illnesses, such as Salmonella, Shigella, and E. coli O157:H7. These pathogens are bacteria that can contaminate food during various stages of production, processing, and preparation. They are known to lead to serious gastrointestinal infections when ingested, often due to improper handling, cooking, or food storage practices.

Understanding these pathogens is crucial for food handlers, as it emphasizes the importance of maintaining hygiene and following food safety protocols to prevent contamination and protect public health. Knowledge about these specific diseases is vital for anyone involved in the food industry to ensure the safety of the food served to customers.

The other options, while related to health concerns, do not pertain specifically to diseases that are transmitted through contaminated food. Allergies may be triggered by specific food items, typically not caused by bacterial or viral contamination. Diabetes and heart disease are chronic conditions influenced by various lifestyle factors, including diet but are not directly linked to foodborne pathogens.
