Acute watery diarrhea is most commonly seen with traveler's diarrhea caused by enterotoxigenic E. coli (ETEC), parasite-induced diarrhea from Giardia and Cryptosporidium spp. and, in cases of food poisoning (ingestion of preformed toxins), from B. cereus and S. aureus.
Diarrhea â loose, watery stools occurring more than three times in one day â is a common problem. There are many causes of diarrhea. Temporary diarrhea lasting three weeks or less could be a symptom of a foodborne illness and is usually related to bacterial, viral, or parasitic infection. Temporary diarrhea may also be caused by food intolerances, food allergies, or reactions to medicines.
