Question

Which of the following does (do)not always require the presence of living bacteria?
A)Intoxications
B)Food poisoning
C)Bacterial diarrhea
D)All of the choices are correct.

Accepted Answer

Intoxications and some forms of food poisoning can be caused by toxins produced by bacteria that may not be present in the food at the time of consumption. Bacterial diarrhea can be caused by living bacteria, but the statement includes "not always," which applies to intoxications and some food poisonings where the bacteria might not be present.
