Food intoxication refers to illness caused by what?

• A. When chemical, toxic metals, or natural toxins that are produced by microorganisms contaminate food Symptoms appear within a few hours
• B. Infections produced by bacteria in the gut; onset in 24-48 hours
• C. Viral infection; onset 1-2 days
• D. Spoilage of food; onset 7-10 days

Answer: (B)

Foodborne illness can come from toxins produced by microbes in food (intoxication) or from live pathogens that actually infect the gut (infection). In this item, the scenario aligns with illness caused by bacteria that infect the gut, with symptoms appearing about 24–48 hours after exposure. That timing fits many bacterial gastrointestinal infections, where the organisms must be ingested, survive the stomach, multiply in the intestines, and then trigger symptoms. Illness due to preformed toxins in food typically shows up much sooner after ingestion, which is why that rapid-onset option doesn’t match this question’s framing. Viral infections and food spoilage have different mechanisms and timelines, so they’re not the best fit here.
