Which organism is commonly associated with food poisoning from contaminated food?

• A. Salmonella
• B. Escherichia coli
• C. Staphylococcus aureus
• D. Listeria monocytogenes

Answer: (A)

Salmonella is the organism most commonly linked to foodborne illness from contaminated foods because it colonizes a wide range of foods and spreads easily through handling and processing. It’s frequently found in raw or undercooked poultry and eggs, dairy products, and produce, and can contaminate foods during processing or via cross-contamination. Ingesting Salmonella typically causes gastroenteritis with diarrhea, abdominal cramps, fever, and sometimes vomiting. Safe cooking to appropriate temperatures and preventing cross-contamination are key prevention strategies.

Other organisms can cause similar illness too—some produce toxins in foods stored improperly, others grow at fridge temperatures, and their specific risk patterns differ—but Salmonella is the most commonly implicated in food poisoning from contaminated foods.
