What type of noninvasive infectious diarrhea is frequent after consuming fried rice?

Fried rice can be associated with a specific type of noninvasive infectious diarrhea caused by Bacillus cereus, particularly due to improper storage and reheating of the rice. This bacterium produces enterotoxins that lead to gastrointestinal symptoms, typically manifesting as diarrhea or vomiting. One common scenario involves cooked rice being left at room temperature, allowing Bacillus cereus spores to germinate and produce the heat-stable toxins that cause food poisoning when the rice is consumed later.

In contrast, the other options listed are linked to different pathogens or mechanisms of disease. For example, Shigella is associated with dysentery and is invasive, causing inflammation of the intestinal lining. Enterotoxigenic E. coli is primarily linked with travelers' diarrhea and watery diarrhea but is not specifically tied to fried rice. Staphylococcus aureus typically causes food poisoning through a different mechanism, often related to high-protein foods, and while it can lead to gastrointestinal symptoms, it is not specifically connected to fried rice. Thus, the identification of Bacillus cereus as causing diarrhea after consuming fried rice is due to its capability to survive cooking as spores and produce toxins when the rice is improperly stored.
