Shigella bacterial infection is caused by?

Shigella bacterial infection is primarily transmitted through fecal-oral contamination. This means that the bacteria can be spread when a person ingests food or water that has been contaminated with feces from an infected individual. This mode of transmission highlights the importance of proper hygiene practices, such as handwashing after using the restroom or before handling food, to prevent infection.

The focus on fecal-oral transmission is significant because it underscores the role of sanitation in food safety. Many foodborne illnesses, including those caused by Shigella, originate from poor personal hygiene and inadequate food handling practices. Understanding this pathway helps food handlers recognize the critical nature of cleanliness in food preparation environments.

Other options might relate to different types of foodborne illnesses or improper food handling practices, but they do not accurately describe the transmission route specific to Shigella. This distinction is essential for food handlers to ensure they are aware of how to prevent such infections in their operations.
