"Cafeteria germ" outbreaks occur with large quantities of food and involve a spore-forming pathogen. Which organism is described?

• A. Clostridium perfringens
• B. Staphylococcus aureus
• C. Salmonella
• D. Listeria

Answer: (A)

In cafeteria outbreaks involving large quantities of food, a spore-forming bacterium that thrives in anaerobic, holding-heat conditions is a classic culprit. Clostridium perfringens fits this pattern because it forms heat-resistant spores that can survive cooking. If the food is kept warm for long periods, these spores germinate and the bacteria grow in the anaerobic environment, producing an enterotoxin that causes gastroenteritis after ingestion. This leads to symptoms like abdominal cramps and diarrhea, typically appearing several hours after eating, and is commonly linked to bulk-prepared meats, gravies, and other dishes held in the danger zone too long. Staphylococcus aureus can also cause food poisoning, but it does not form spores. Salmonella and Listeria are not spore-formers and have different typical sources and patterns of illness, so they don’t fit the “spore-forming in large-quantity cafeteria foods” scenario.
