Which of the following agents has foodborne gastrointestinal infections as one of its forms?

• A. Anthex
• B. Anthrax
• C. Botulinum
• D. Salmonella

Answer: (A)

Foodborne gastrointestinal infections arise when a microbe is ingested and causes inflammation of the gut. Among the listed microbes, Salmonella is the classic cause of gastroenteritis from contaminated foods such as poultry, eggs, dairy, and produce. Infected individuals typically experience diarrhea, abdominal cramps, and fever after exposure to contaminated food.

Botulinum-related illness comes from a toxin produced in food, causing nerve symptoms rather than a true gut infection, so it’s not categorized as a gastrointestinal infection. Anthrax can involve the GI tract if ingested, but that route is rare and not the typical example of foodborne GI infection used in exams. The option that best fits the concept of foodborne gastrointestinal infection is Salmonella.
