Which statement best defines food infection?

• A. Infection occurs when toxins are produced in food and then eaten.
• B. Pathogen invades the body after consumption of contaminated food; growth in food may not be necessary.
• C. All illnesses are caused by toxins in food.
• D. Infection only occurs when there is growth of the pathogen in the body after ingestion.

Answer: (B)

Food infection means illness caused by viable pathogens that are ingested and then invade and multiply in the body, typically in the gut. The key idea is that the harm comes from the pathogens themselves after ingestion, not from toxins produced in the food. Growth in the food is not a requirement for this illness to occur; the pathogens just need to be alive when eaten and capable of establishing infection in the host. This is why the best statement describes the pathogen invading the body after consuming contaminated food, with growth in the food not being necessary. The other options describe toxin-related illness or overstate the role of growth inside the body, which aren’t defining features of an infection.
