Gastrointestinal diseases from animals such as E.coli, Cryptosporidium parvum, Campylobacter, and Salmonella have the potential to be passed from animals to humans, causing serious illness in the latter. In most cases, digestive disorders are caused by food and water. However, any of these may be acquired via interaction with animals or their habitats.

In recent years, there has been an increase in the number of intestinal disorders related to venues where the public interacts with farm animals (e.g., petting zoos, state or county fairs, educational farms). 


Common Gastrointestinal diseases from animals include:

  • Salmonellosis

The medical team may question you about your symptoms and recent activities, among other things, to assist them in reaching a diagnosis since there are a variety of disorders that come under the category of gastrointestinal (GI) ailments.

Your physician may prescribe the following tests:

  • Urine test
  • Blood tests
  • Stool sample examination


Self-care methods are the suggested therapy in the majority of instances. Viruses and parasites are not susceptible to antibiotic treatment. In primary cases of bacterial infection, antibiotics may prolong the condition and raise the likelihood of a recurrence, although medicines may aid under challenging situations.

Additionally, antibiotics may have hazardous side effects in some illnesses. Your physician can assess if you or your kid need antibiotics. Your doctor may urge you to avoid high-fiber foods that may exacerbate diarrhea. Additionally, they may suggest over-the-counter drugs that neutralize stomach acid or treat nausea, abdominal discomfort, and diarrhea. Hydration is the most critical self-care therapy for adults and children with GI illnesses.
