What is a crucial step in preventing shigella spp infection?

Hand washing is a crucial step in preventing shigella spp infection because this bacteria is primarily transmitted through the fecal-oral route. It can be spread when infected individuals do not wash their hands properly after using the restroom and then handle food or food contact surfaces. Effective hand washing practices help eliminate pathogens from the hands, significantly reducing the risk of contamination and subsequent illness.

While proper cooking of meat and purchasing from recommended suppliers are important food safety practices, they are not directly effective against preventing shigella infections, which are less about cooking and sourcing and more about personal hygiene. Wearing gloves while serving food can add an additional layer of protection, but it should not replace the fundamental practice of hand washing. Gloves can still become contaminated, so clean hands are essential. Thus, diligent hand washing is key to preventing the spread of shigella and protecting public health.
