How is Shigella spp. primarily transmitted?

Shigella spp. is primarily transmitted through fecal-oral transmission, which occurs when small amounts of fecal matter from an infected person enter the mouth of another person. This can happen in various ways, such as consuming food or water contaminated with fecal matter, or through direct contact with an infected individual who has not practiced proper hand hygiene.

Fecal-oral transmission is particularly common in settings with inadequate sanitation and hygiene practices, making it crucial for food safety professionals to emphasize the importance of proper handwashing and food handling practices to prevent outbreaks of Shigella. The bacteria can survive in water and on surfaces, which can further facilitate its spread if hygiene standards are not maintained.

Understanding the transmission route of Shigella spp. is essential for developing effective prevention strategies and reinforces the importance of good personal hygiene and sanitation practices in food safety.
