Causes of Watery Diarrhea
5. Food
The ingestion of food that has not been prepared properly can cause diarrhea. This is especially true for those who consume raw food. For example, dairy food can be contaminated by Salmonella or Campylobacter species: eggs by Salmonella species; meats by Salmonella, Campylobacter, Aeromonas, and Clostridium perfringens species; pork by Clostridium perfringens and Yersinia enterocolitica; poultry by Campylobacter species; ground beef by enterohemorrhagic Escherichia coli; seafood by Plesiomonas, Vibrio, Aeromonas, and Astrovirus species; vegetables by Closterium perfringens and Aeromonas species; and oysters by Vibrio, Plesiomonas, and Calicivirus species.
Water contamination is also a major reservoir for many pathogens (Entamoeba, Cryptosporidium, Giardia, Shigella, Aeromonas) that can cause diarrhea
