Final answer:
Raw eggs are one of the foods commonly associated with Salmonella Typhi. Thorough cooking and handwashing are preventive measures, as both animal-based foods and produce can be contaminated.
Step-by-step explanation:
One of the three foods commonly linked with Salmonella Typhi is raw eggs. Salmonella is a bacterium that can be found in various foods, including raw and undercooked meat, poultry, dairy products, and seafood. It's important to note that while Salmonella can be part of normal intestinal microbiota, salmonellosis is typically caused by exogenous agents found in contaminated foods or surfaces. Properly cooking food and washing hands are ways to reduce the risk of transmission. Not only animal-based foods can be affected; produce such as leafy greens and fresh fruits have also been linked to outbreaks.
